Hi folks,

Here comes a new SC problem of this week, just for you. Do post your detailed analysis and we will give Kudos to you if you get correct. :)

A new study suggests that different species of mice have different burrow design: a lab-raised mouse too can build species-specific burrow due to its genes, carrying various DNA combinations of burrow creation in genome.

A. a lab-raised mouse too can build species-specific burrow due to its genes, carrying various DNA
B. a lab-raised mouse too can build species-specific burrow because of its genes that carry various DNA
C. a mouse raised in the lab builds species-specific burrow so that its genes carry various DNA
D. a mouse in the lab can build species-specific burrow as its genes can carry various DNA
E. a lab-raised mouse too can build species-specific burrows because of their genes carrying various DNA

Official answer and detailed solution will be posted after a few responses.
Happy Practicing. :)


of course it is E. Seems like a Classic GMAT problem. What's new? the colon?


Hi docdrizzeally.

E) a lab-raised mouse too can build species-specific burrows because of their genes carrying various DNA

I think E is incorrect because "a lab-raised mouse" is singular ==> "their genes" is wrong. It should be "its genes". IMO, B is correct.

Regards.

Hi everyone,

First of all, thank you all very much for your responses. It's really good to see such nice and analytical responses. This definitely helps to learn in a much more effective manner. SO here comes the official explanation for this one.

A new study suggests that different species of mice have different burrow design: a lab-raised mouse too can build species-specific burrow due to its genes, carrying various DNA combinations of burrow creation in genome.

Image

• This sentence presents facts.
• Different species of mice build burrows of different designs.
• Even a mouse raised in lab can make a burrow specific to its species.
• Burrow making is genetic as genes carry DNA combinations of burrow making in every species.

Image

Error Analysis

• Clause 1: A new study suggests
• Clause 2: that different species of mice have different burrow design:
• Clause 3: a lab-raised mouse too can build species-specific burrow due to its genes, carrying various DNA combinations of burrow creation in genome.

1. Use of “due to” is incorrect in this sentence because it has been used to modify the verb in this sentence, more specifically to present the reason for the verb – how can a lab-raised mouse build species-specific burrow. “Due to” can only be used to explain the noun and not a verb.

2. The comma + verb-ing modifier “carrying” modifies the preceding clause. This modification does not make much sense as it seems to suggest that mice carry various DNA combinations. Logically, it is the genes in the mice that carry DNA combinations. Hence, we need a modifier that refers to “genes”.

PoE

A. a lab-raised mouse too can build species-specific burrow due to its genes, carrying various DNA: Incorrect for the reasons stated above.

B. a lab-raised mouse too can build species-specific burrow because of its genes that carry various DNA: Correct Answer. It corrects both errors of choice A and does not introduce any other errors.

C. a mouse raised in the lab builds species-specific burrow so that its genes carry various DNA: Incorrect.

Error 1 – Use of simple presents “builds” is incorrect because the original sentence presents the ability of the lab raised mouse to build species-specific burrow by saying “can build”. This choice suggests that it is a general fact that lab- raised mice make species-specific burrow.
Error 2 – Use of “so that” is incorrect. This phrase is used to present the result of the preceding clause. This usage distorts the intended meaning.

D. a mouse in the lab can build species-specific burrow as its genes can carry various DNA: Incorrect.

Error 1 – “A mouse in the lab” does not mean the same as “a lab-raised mouse”. A mouse in the lab can be just any mouse there and not necessarily the mouse that has been raised there.
Error 2 – Per the original sentence, it is a general fact that “genes” carry various DNA combinations. Per this choice, “can carry” suggests the ability of genes to carry various DNA combinations. This is not the intended meaning.

E. a lab-raised mouse too can build species-specific burrows because of their genes carrying various DNA: Incorrect. Pronoun “their” should logically refer to “mouse”. But grammatically, plural pronoun “their” does not agree in number with the singular noun “mouse”.

Image

1. “Due to” cannot be used to present reason for the verb. It can only describe noun entities. “Because of” is the correct expression to do so.
2. We must use the correct Modifier must be used correctly to modify the entity it is supposed to modify.
3. “Can verb” presents the ability, while simple presents tense presents general truth.
4. We must use correct expressions to communicate the intended meaning. For example, lab-raised mouse is not the same as mouse in the lab.

Thanks. :)

Hi Egmat Team,
I know this is an old post, but would appreciate if you could help clarify below doubts:
a. How does have different burrow designs in sentence infer to build burrows of different designs in meaning analysis.
b. in underlined potion, it say lab raised mouse too, because of word too I was searching for various other activities that lab raised mouse performs in remaining sentence. Needless to say, I was incorrect. Can you advice why I faltered?
WR,

Hi Arpit,

Thank you for the query. And I apologize for the delay in posting this response.

a. The sentence talks about burrow designs of various species of mice. It is a common fact that mice build their own burrows. From the sentence, we get to know that different species have different burrow designs. Hence, it can be easily deduced that different species of mice build different kinds of burrow.

b. The word too has been used to mean also. The sentence talks about two different kinds of mice – lab-raised mice and mice staying in natural habitat.
Since the first part of the sentence talks about the second type of mice, the author uses too for lab-raised mice as he states that lab-raised mice also who have never been in their natural habitat can still make their species-specific burrows because of their genes.

Please read the sentence very carefully. When you read the sentence for the first time, do not look for grammatical errors yet. First, get the gist and the context of the sentence. In short, focus more on meaning-based approach.

Hope this helps. :)

Thanks,
Shraddha

egmat can you please explain to me when "so that" is correct in a sentence. I am not referring to so + adjective that.
I did a sentence correction problem and so that was correct.
Thanks,
Matthew
