Update:Just added the free concept on Like (first of 4 concepts) on e-GMAT. Just register at e-GMAT and get cracking. The concept contains 10 questions + 5-6 additional examples.

Two seemingly simple words – like and as – often create havoc in the minds of test takers when they both appear in the answer choices in a sentence correction question. People wonder about the following two points:

1. For stating comparison should I use “as” or “like”?
2. When is “as + noun” correct and when is “as + clause” correct?

Lets consider for example the following GMATPrep question.

As with those of humans, the DNA of grape plants contains sites where certain unique sequences of nucleotides are repeated over and over.
A. As with those of humans, the DNA of grape plants contains sites where
B. As human DNA, the DNA of grape plants contain sites in which
C. As it is with human DNA, the DNA of grape plants, containing sites in which
D. Like human, the DNA of grape plants contain sites where
E. Like human DNA, the DNA of grape plants contains sites in which

The two main things to keep in mind to solve such questions are as follows:
Understand what meaning like and as communicate
• Understand the intended meaning of the sentence so that you can wisely choose the appropriate word.

In this article we will first discuss why there is a confusion with regards to usage of like and as. Then we will apply our knowledge in a structured step by step manner to solve the above GMATprep question.

LIKE AND AS - THE POINT OF CONFUSION

‘As’ plays multiple roles and thereby is used in different grammatical constructions, one of which coincides with how like is used.

Both ‘like’ and ‘as’ are used for stating a comparison. So often people are confused whether they should use ‘like’ or ‘as’ to state the comparison. Furthermore, ‘as’ is also used to present function. And this brings us to another point of confusion. How to use 'as' correctly when presenting a comparison and when presenting a function. The table below provides the answers. Note the similarity in usage between the shaded portions.

Because ‘as’ and ‘like’ are followed by nouns but they do so while presenting two different meanings, there is often a confusion regarding the intended meaning communicated by the sentence and the grammatical correctness of the sentence.

Now lets see this in detail.

LIKE AND AS -STATE COMPARISON

Both ‘like’ and ‘as’ are used to state comparisons. For example:
• Amy takes care of the children in the day care like a mother. 
• Amy takes care of the children in the day care as a mother does.
Both sentences are correct. Both the sentences above convey the meaning that Amy takes care of the children “in the same way” as a mother takes care of her children.
But notice the usage here – ‘like’ is followed by a noun and ‘as’ is followed by a clause. This grammatical construction should be kept in mind.

AS - CAN ALSO PRESENT FUNCTION

Apart from stating comparison, “as” can also be used to state “role” or “function”. For example:

John has joined the organization as a researcher.

In this sentence, ‘as’ does not show a comparison. This sentence implies that John is indeed a researcher in the new organization. Notice that per this sentence John has not been compared to a researcher. John is indeed a researcher. So his role has been presented. And hence ‘as’ is used to present role or function of a person.

Notice the grammatical construction – ‘as’ has been followed by a noun. This should always be kept in mind.

LIKE AND AS – CONFUSION RESOLUTION

Now that we understand the source of confusion between like and as, lets see how we can resolve this confusion. The most sure shot way of resolving this confusion is to understand from the context of the sentence whether a comparison needs to be presented or function needs to be presented. Once you determine this, then you may use like and as appropriately to state the intended meaning.

Lets take John’s example again:

John has joined the organization as a researcher.

Here is my thought process:

Step 1. I see the word “as”.

Step 2. I ask the question – “does the sentence intend to draw a comparison or state a role”?

Step 3. I answer the question from the context –
i. John has joined the organization.
ii. Lets first find out if comparison makes sense here.
• Saying that John has joined organization as a researcher does – is non-sensical. It is not a common characteristic of a researcher to join organization. So stating comparison is not logical here.
iii. Lets now find if role has been presented here.
• Saying that John will play a role of a researcher in this new organization makes perfect sense. So here as has been used to present role.

Step 4. I check if grammatically “as” has been used appropriately.
i. Yes, since “as” is used to present function, it should be followed by a noun. In this sentence “a researcher” is a noun. So correct.

Lets take another example:

John has joined Biotech industry as his brother.

Here is my thought process:
Step 1. I see the word “as”.

Step 2. I ask the question – “does the sentence intend to draw a comparison or state a role”?

Step 3. I answer the question from the context –
i. John has joined the organization.
ii. Lets first find out if comparison makes sense here.
• Saying that John has joined biotech industry as his brother did makes sense. His brother joined biotech industry and so did John. So stating comparison is logical here.
iii. Lets now make sure that stating a “role” is clearly non-sensical
• Saying that John will play a role of his own brother in biotech industry is non-sensical. What does being a brother in an industry mean? Nothing. Yes being a researcher in an industry means something but not being a brother. So notice how context drives the logical and illogical meaning.

Step 4. I check if grammatically “as” has been used appropriately.
i. No, since “as” is used to present comparison, it should be followed by a clause. In this sentence “his brother” is a noun and hence this sentence is not correct. It should be corrected in one of the following ways:
• John has joined Biotech industry as his brother did.
• John has joined Biotech industry like his brother.

STRUCTURED APPROACH TO SOLVING GMAT SC QUESTIONS

With this understanding, now we can solve the GMATPrep question. Here we will integrate our knowledge of as and like with e-GMAT 3-step process.

1. Understand the meaning of the original sentence.
2. Determine the errors in the original sentence.
3. Apply process of elimination to find the correct answer.

Our knowledge of “like” vs “as” will be applicable in step 1 – we will determine the intended role of the word in the context of the sentence. Then our knowledge of grammatical construction of like and as will be applicable in step 2 – we will make sure that the word has been used appropriately.

Free Course

Can you apply the process above to solve the GMATPrep question above. Few of you who articulate the solution well will get OG Verbal SC solutions - our Video course for SC solutions in OG Verbal Second solution - a \$39 value free of charge. Get cranking as we will declare the results by June 7.

A. As with those of humans, the DNA of grape plants contains sites where
B. As human DNA, the DNA of grape plants contain sites in which
C. As it is with human DNA, the DNA of grape plants, containing sites in which
D. Like human, the DNA of grape plants contain sites where
E. Like human DNA, the DNA of grape plants contains sites in which

My thought process behind answer E:
The sentence is trying to convey how the DNA of grape plants behave similarly to human DNA (a comparison).
"As" needs to be followed by a clause and there is no verb in "As with those of humans"
"As" must be followed by a clause so B can be thrown out.
C can be thrown out because "it" is ambiguous.
"Like" must be followed by a noun. D can be thrown out because human is being compared to DNA which is incorrect.

E is correct. "Like" is followed by the noun "human DNA" demonstrating proper usage.

As with those of humans, the DNA of grape plants contains sites where certain unique sequences of nucleotides are repeated over and over.
A. As with those of humans, the DNA of grape plants contains sites where
B. As human DNA, the DNA of grape plants contain sites in which
C. As it is with human DNA, the DNA of grape plants, containing sites in which
D. Like human, the DNA of grape plants contain sites where
E. Like human DNA, the DNA of grape plants contains sites in which

IMO: E

1. The intended meaning:
(1) a comparison between human DNA and grape DNA: these two are somewhat similar
(2) here's the similarity: they both contain sites where some nucleotide sequences are repeated

2. what's wrong with A?
As mentioned above, here the meaning is "comparison", not "function". Therefore, we need either "as + clause" or "like + noun".
Although sometimes "as" can be followed by a prepositional phrase (in which case the expression is indeed eclipse from the prototype "as + clause", for example, "As at school, I study hard at home."), here "as with those of humans" does not make sense.
In the case of "As with A, __________." the sentence should be comparing "with A" with another prepositional phrase, such as "with B". However, "with B" does not present.
Also, "those" do not have clear referent.
In a word, "As with those of humans" is problematic.

3. POE
Look vertically. The beginning of underlined part is definitely a split.

B. "As human DNA, ..." wrong.

C. "As it is with human DNA, the DNA of grape plants"
here "it" has no referent.
btw. this wrong expression reminds me of a correct idiom "as is the case with". it's interesting to note that GMAT sometimes distort this expression to creat wrong choices

D. " Like human, the DNA of grape plants"
This choice illogically compares human with DNA.

E. Correct.

Its E,

Here is my reasoning

Here two things compared are DNA of humans and DNA of grape plants, so this sentence is incorporating comparison, so we need Like to comaare the two nouns,

As far as the options only E fits best in the sentence:)

GMATPREP QUESTION SOLVED

As with those of humans, the DNA of grape plants contains sites where certain unique sequences of nucleotides are repeated over and over.
A. As with those of humans, the DNA of grape plants contains sites where
B. As human DNA, the DNA of grape plants contain sites in which
C. As it is with human DNA, the DNA of grape plants, containing sites in which
D. Like human, the DNA of grape plants contain sites where
E. Like human DNA, the DNA of grape plants contains sites in which

STEP 1 – UNDERSTAND THE MEANING

As with those of humans, the DNA of grape plants contains sites where certain unique sequences of nucleotides are repeated over and over.

This sentence presents a comparison. Similarity between the DNA of humans and grape plants has been presented. The DNAs of both the humans and the grape plants contain sites where some unique sequences of nucleotides are repeated over and over. It is illogical here for “as” to present “role” because DNA of grape plant cannot play role of human DNA. It is completely non-sensical.

STEP 2 – IDENTIFY THE ERRORS
• Clause 1 - As with those of humans, the DNA of grape plants contains sites
• Clause 2 - where certain unique sequences of nucleotides are repeated over and over

1. SV – Both SV pairs agree in number
2. Pronoun Number – Plural “those” does not agree in number with its singular antecedent DNA
3. Modifier – where correctly modifies sites
4. Other – purpose of “with” in ‘as with those of humans’ is not clear. It does not serve any purpose and makes the sentence wordy.

STEP 3 – PROCESS OF ELIMINATION TO FIND THE CORRECT ANSWER

A. As with those of humans, the DNA of grape plants contains sites where
Eliminated as discussed
B. As human DNA, the DNA of grape plants contain sites in which
• As needs to be followed by a clause here to present comparison.
• Singular DNA does not agree with plural verb contain.
C. As it is with human DNA, the DNA of grape plants, containing sites in which
• Subject DNA does not have a verb.
D. Like human, the DNA of grape plants contain sites where
• Comparison is not logical. Human cannot be compared to DNA.
• Singular DNA does not agree with plural verb contain.
E. Like human DNA, the DNA of grape plants contains sites in which
Correct. In this sentence, the intended comparison has been presented using ‘like’, which has been used correctly by following it up with a noun.

This post was
BOOKMARKED
Hi Damham17 and Thulsy,

First of all I would like to thank you both for taking the time to write detailed analysis of this question.

What you did well

I appreciate you taking the time to submit your analysis for this question. You got the right answer for the right reasons. Choice E is indeed the right answer and Like has been used correctly to convey the intended comparison. So you definitely got the meaning right and also correctly found out the appropriate grammatical construction for the sentence.

Where could you have done better

Now, I do notice small gaps in the elimination of answer choices. As I have explained in the solution, the Choices A and C have been eliminated because of SV errors.

In choice A, SV do not agree in number. Choice A also contains pronoun number error. In choice C, verb does not exist for subject DNA.

Now comes the question is "as with" incorrect? The answer is "no". See "as can be followed by a prepositional phrase", if we see application of ellipsis.

@Thulsy - you have touched upon this point in your response and I am glad that you did recognize that as can be followed by prepositional phrase. But I see that there is a slight gap in your understanding. When as is followed by a prepositional phrase, it is not required that the entity that it is compared with should also be a prepositional phrase. (On a tangential but definitely related note - I like your thought process - you are thinking about the intended meaning, then you are figuring out what is wrong with choice, and then you are applying splits in the answer choices - perfect approach!! Just read my comments below and see if you can add a bit more to your second step.)

Coming back to as + prepositional phrase - Lets take an example here:

"As with any well-executed marketing plan, sales jumped whenever fans were goosed with new media." - courtesy nytimes.com
Here the usage of "as with" is absolutely correct. Why? Because ellipsis is at play, How? the words "is the case" have been omitted to create a much more concise sentence.

So in choice A as well, we can assume the omitted words to be - as is the case with those of humans, ....- So here usage of 'as' is appropriate. But usage of "those" is not correct as stated earlier.

Hope this helps. Actually we cover this aspect of "as" in significant detail in the concept titled "Usage of As", which is part of "e-GMAT in-depth Series".

Who Gets the Award

- I know we said that we will be selecting one person for the award. However, for your efforts, I will select both of you for the award. Now please note that this selection is not for the correctness of the response. In fact as you have seen, there are some key gaps in your analysis. You both have been selected for your keen efforts.

Almost everyday, I see this - if one error type is blatantly obvious as is in this case - like vs as - test takers tend to focus on that aspect only. Although, this approach may work well for easy questions, it is clearly not the correct approach for medium to difficult questions. In fact, you should focus on all the major types of errors. Per the e-GMAT 3-step process, we say that when you review the original sentence, you should understand the meaning and the sentence structure of this original sentence in detail. This helps in identification of all errors that are present in the original sentence. And this helps in overall understanding of the question.

So both of you win the access to OG VR2 SC solutions. We have solved ALL OG VR2 questions using the e-GMAT process. As you review these solutions, you will be able to see the process in action on official questions.

How to Avail the Award

Keep up your good efforts!! Let learning be an enjoyable and continuous experience...

Regards,

Payal

Wow I'm thrilled!! Thank you so much Payal!

Just as you said, since this question appears in this post (which deals with AS vs. LIKE), I tend to be "hypersensitive" to this as/like issue while overlooking other important issues, such as the sentence fragment in Choice (C). Also, the "as" itself in original sentence has no problem, rather the "with" and "their" have problems.

So I want to confirm if I get this. Suppose Choice (A) were written as:
As with that of humans, the DNA of grape plants contains sites where certain unique sequences of nucleotides are repeated over and over.
Would it be correct then?
I think it would be correct, but inferior than Choice (E), which is more concise. Am I correct?
--update: just read your post one more time and I changed my mind... I think "as with" is still incorrect. in your example:
"As with any well-executed marketing plan, sales jumped whenever fans were goosed with new media."
this sentence is comparing the case (whole idea) that "fans were goosed with new media" with the case with "any well-executed marketing plan".
But this question is not comparing two whole-ideas, rather it is comparing two nouns: human DNA vs grape DNA. So "like" is appropriate.
Am I correct?

Thank you so much for pointing out my gap, and for your in-depth analysis. I've learned a lot.

Hi Akrish1982,

As with human DNA, the DNA of grape plants contains sites where unique sequences of nucleotides are repeated over and over.
This sentence is still incorrect.
1. Function of “with” is unclear in this sentence. We may ask what with human DNA? We don’t get any answer to that.

Hope this helps.
Thanks.

thank you Shraddha. I thought "as with" was correct based on Payal's note:
Quote:
Now comes the question is "as with" incorrect? The answer is "no". See "as can be followed by a prepositional phrase", if we see application of ellipsis.

(On a tangential but definitely related note - I like your thought process - you are thinking about the intended meaning, then you are figuring out what is wrong with choice, and then you are applying splits in the answer choices - perfect approach!! Just read my comments below and see if you can add a bit more to your second step.)

Coming back to as + prepositional phrase - Lets take an example here:

"As with any well-executed marketing plan, sales jumped whenever fans were goosed with new media." - courtesy nytimes.com
Here the usage of "as with" is absolutely correct. Why? Because ellipsis is at play, How? the words "is the case" have been omitted to create a much more concise sentence.

How do we solve this question based on the methodolgy above?

More than thirty years ago Dr. Barbara Mc-Clintock, the Nobel Prize winner,
reported that genes can “jump,” as pearls moving mysteriously from one necklace to another.
(A) as pearls moving mysteriously from one necklace to another
(B) like pearls moving mysteriously from one necklace to another
(C) as pearls do that move mysteriously from one necklace to others
(D) like pearls do that move mysteriously from one necklace to others
(E) as do pearls that move mysteriously from one necklace to some other one

When I tried, this comes up a comparison and not a function. If genes can jump is being compared - I tried all three choices with as, but none of them were parallel as none had ability (using or not using can). but then I forcefully chose one of them. Please help.

Hi there,

More than thirty years ago Dr. Barbara Mc-Clintock, the Nobel Prize winner, reported that genes can “jump,” as pearls moving mysteriously from one necklace to another.

You are absolutely correct in your meaning analysis and in determining that this sentence intends comparison and not presenting the role of anything. I would just like to add that “pearls moving mysteriously…” is a metaphor. Pearls have been compared to genes only in way to present an image of pearls moving mysteriously from one necklace to another. In reality, this action does not take place. This comparison has been cited just to say that genes “jump” as you would imagine a pearl moving from one necklace to another.

“As” when used for comparison, should be followed by either “a clause” or “a prepositional phrase”. In this sentence, “as” is followed by noun entity. Also note that the intention is not to compare the movement of pearl with “jumping” of the genes. The real comparison is only between “genes” and “pearls”. The movement of pearl has just been used for imagery. Hence, use of “like” is correct for this sentence.

POE

(A) as pearls moving mysteriously from one necklace to another: Incorrect for the reasons discussed above.

(B) like pearls moving mysteriously from one necklace to another: Correct. This choice correctly uses “like” for comparison. “Like” is followed by “pearls”, a noun entity. The verb-ing modifier “moving…” presents the intended imagery.

(C) as pearls do that move mysteriously from one necklace to others: Incorrect. This choice means that pearls actually move from one necklace to another. This is not logical. Also the modification of "that" is not correct as it is not preceded by a noun entity but a verb.

(D) like pearls do that move mysteriously from one necklace to others: Incorrect. “Like” is followed by a clause “pearls do”.

(E) as do pearls that move mysteriously from one necklace to some other one: Incorrect. Repeats the same meaning error of Choice C.

Hope this helps.
Thanks.

thank you Shraddha. I thought "as with" was correct based on Payal's note:

Now comes the question is "as with" incorrect? The answer is "no". See "as can be followed by a prepositional phrase", if we see application of ellipsis.

@Thulsy - you have touched upon this point in your response and I am glad that you did recognize that as can be followed by prepositional phrase. But I see that there is a slight gap in your understanding. When as is followed by a prepositional phrase, it is not required that the entity that it is compared with should also be a prepositional phrase.

From my experience of Gmat study the SC is one of the most important part of prep in which we should spend some time on every question to analyse why the answer is wrong for reasons other than selected by us.

(A) as pearls moving mysteriously from one necklace to another - I can see only one error - usage of as pearls is wrong : AS+ Clause should be the pattern
(B) like pearls moving mysteriously from one necklace to another - correct usage of like - Like+ noun
(C) as pearls do that move mysteriously from one necklace to others - other than wrong usage of as, one necklace to others is wrong too.
(D) like pearls do that move mysteriously from one necklace to others - same as above
(E) as do pearls that move mysteriously from one necklace to some other one - wrong usage
