I am still confuse about - THAT.
Is that singular or plural..?
for eg: Expectations that are fulfilled ....<insert something>.. ..
Here that ----> expectations----->plural.

Someone plz clarify.

Hi smokering.
The two "that" are different. The one in the question is "demonstrative pronoun". The one that you mention is "relative pronoun".

* Demonstrative pronoun can function by themselves as substitutes for specific nouns / antecedents. ==> The parallel nature must be maintained.
For example:
WRONG: The books I borrowed at the library yesterday are similar to THAT of your. "books" - plural is not parallel to "that" which refers to singular antecedent.
CORRECT: The books I borrowed at the library yesterday are similar to THOSE of your.

*Relative pronoun is used to introduce one type of subordinate clause called a relative clause
"that" modifies the preceding noun/noun phrase. It does not matter the preceding noun/noun phrase is singular or plural.
For example: The cars THAT have introduced in the auto show are very expensive.

Hope it helps.

IMO B. What does the answer guide say?

The non-underlined part start with were unable to perform..., whose subject should computers, as dictated by the meaning, not H/w or S/W
A has a comparison problem - you have limitationS in the 1st half but you that in the 2nd half of the comparison. that is singular but we need those to compare it with "limitationS"
So go with B.

Cheers

A good question, it involves importance of focus on non underlined portion to identify the right answer.

The first personal computers had severe hardware and software limitations similar to that of a modern wristwatch and so were unable to perform the complex operations necessary for today's processor-intensive applications.

A) The first personal computers had severe hardware and software limitations similar to that of a modern wristwatch -- no proper reference of that available.

B) The first personal computers had severe hardware and software limitations similar to a modern wristwatch's -- comparison is ok also subject matches with sentence in non underlined part.

C) The severe hardware and software limitations of the first personal computers were similar to those of a modern wristwatch -- comparison is ok -- but limitations does not qualifies as logical subject of non underlined portion.

D) The first personal computers' severe hardware and software limitations were similar to those of a modern wristwatch -- similar to C

E) The severe hardware and software limitations of the first personal computers were similar to that of a modern wristwatch -- same as A

I do not think the difference is anything more than notional or customary. We can always have a phrase as ‘the computer’s circuit’ or ‘the interest of the teenagers’.
Therefore, when you see such a thing, perhaps it is better to ignore it totally, as I do not think GMAT will be keen on testing this aspect
However, there are other solid reasons to dump both C and D because the sentence structure is faulty with the subject of the first IC unable to stand for the subject of the second IC logically and hence both these choices should be considered fragments. One must look for such reasons.

A) The first personal computers had severe hardware and software limitations similar to that of a modern wristwatch :that cannot refer to plural noun when used as pronoun,we need those
B) The first personal computers had severe hardware and software limitations similar to a modern wristwatch's
C) The severe hardware and software limitations of the first personal computers were similar to those of a modern wristwatch not parallel to so were we need computers
D) The first personal computers' severe hardware and software limitations were similar to those of a modern wristwatch not parallel to so were we need computers
E) The severe hardware and software limitations of the first personal computers were similar to that of a modern wristwatch not parallel to so were we need computers

B) The first personal computers had severe hardware and software limitations similar to a modern wristwatch's: Correct.

The X had many problems similar to Y. The comparison is between personal computers and wristwatch. Not between problems of computers and problems of wristwatch.
That of/ those of is not required

Correct me if I am wrong..!!

Hi chetan2u / daagh,

What is the difference between Option C and D
C) The severe hardware and software limitations of the first personal computers were similar to those of a modern wristwatch
D) The first personal computers' severe hardware and software limitations were similar to those of a modern wristwatch.

I have learnt that we we try to avoid possessive's of non living thing.

Eg-
Scenario 1:
A) The shoes of Jim.
B) Jim's shoes.

Here we give preference to B.

Scenario 2:
A) The ABC law of government.
B) Government's ABC law.

Here we give preference to A.

In the above-mentioned examples its just the question of preferences but actually the meaning is same. (Correct me if I am wrong)

What to do if we come across any options like in this question.

Thanks and Regards,
Prakhar

hi,
It may be correct that few follow the rule avoiding the 'possessive ' of inanimate nouns. But that is not followed in GMAT and most of the cases in real world..
'S or of are ok till the time they are not interfering in the meaning part of it.
Generally this will not be a reason to eliminate a choice..

eg 1- A of B is similar to (that/those) of C.
Here that/those refer to A.

Eg 2- B's A is similar to (that/those) of C.
Here that/those refer to B.

this is again subjected to condition as what structure is available to you ---->by this i mean that you have to select an option that is MOST PARALLEL -----> so "A of B is similar to (that/those) of C" is MORE PARALLEL THAN "B's A is similar to (that/those) of C." ---->by this i mean that your example 2 is NOT WRONG but is inferior to your example 1 --->but TRUST ME GMAC will never make you choose between these TWO options (example 2 is ALSO correct but given a option of example 1 ,it will be prudent to pick option 1)

pronouns such as THAT / THOSE create new copies so by that standard they can refer to things mentioned in previous clause WITHOUT CARRYING the MODIFIERS in the previous clause

please note that here both C and D are WRONG for PARALLELISM issue and not for the COMPARISON issue ---ALSO the GUIDELINE that you have pointed is TRUE (that non living things CANNOT POSSESS); however do not use it as an ELIMINATOR

Although i went for the C option,,but now after reading the explanation it seems as if the parallelism is not maintained in the option C,,,am I right?
first personal computer's must be followed by second clause modern wristwatch's limitations,,,,???

C is passive thats one reason. GMAT prefers active voice. In this comparison question the limitations is compared to a modern watch which is singular we need plural.

A The first personal computers had severe hardware and software limitations similar to that of a modern wristwatch

only B fits the bill. Hope that helps.

Amazing question.. This question is not a rapid fire question as it will take 1 min easily.

But it demand us to spend at least one min.. quick response to this question would prove dangerous..

"Parallelism" is the concept behind it.. But sometimes hard to tackle.

we dont need that of / those of because WRISTWATCH'S (posessive form is already their.

When we use the possessive case, we are comparing limitations to a modern wristwatch limitation? In other words, we are comparing a plural noun (limitations) with a singular noun (wristwatch limitation)? If this is correct why A cannot be the answer? If Im wrong, how can a modern wristwatch's refer to limitations (plural) and not limitation (singular)

Thks!
