Primates with fully formed craniums

by pareekbharat86 » Sun Oct 13, 2013 11:57 pm
This is a Sentence Correction question featuring on page 380 in the Kaplan GMAT Premier 2014 .

Ques:

Unlike other primates, which are born with fully formed craniums, a newborn human baby's cranium consists of eight bones that take years to fuse together fully, allowing the brain to grow much larger during those early years.

a. fully form craniums, a new born human baby's cranium
b. fully formed craniums, newborn human babies have craniums that
c. a fully formed craniums, a human baby's cranium
d. fully formed craniums, a human is born with a cranium that
e. a fully formed cranium, the cranium of a newborn human baby

The OA is D.

Is it correct to write that primates are born with craniums (plural) and not cranium (singular)?
Thanks,
Bharat.

Hi pareekbharat86,

This SC begins with the word "unlike", so it's going to involve Comparisons. The rule for these types of SCs is that "we MUST compare LIKE things, the number doesn't matter." Since the first part of the comparison is "primates", the second part MUST be something that is comparable to "primates" (although it can be a singular or plural noun because the number doesn't matter).

The ONLY answer that offers a valid comparison is [spoiler]D (a human is comparable to primates)[/spoiler]

As to your question, primates (plural) have craniums (plural). IF the sentence were rewritten a bit, then it could switch to singulars (eg "primates are born each with a cranium...").

Unlike X, Y is correct idiom. So a b c and e are wrong. Also, observe here the discussion is about the primates and humans. Primates needs craniums and a human needs a cranium, plural needs plural, singular needs singular.
You can, for example never foretell what any one man will do, but you can say with precision what an average number will be up to!

i love this question

Unlike other primates, which are born with fully formed craniums, (their isnt any mistake till this part). primates are compared with what? with "a newborn human baby's cranium" no its wrong primates can be compared with human being but one cant compare it with human baby's cranium. so definitely one need a remove a new born human baby's cranium with human being. so choices A, C and E are rejected.

between B and D. D is the right option why?
primates, which are born with fully formed craniums, a human is born with a cranium.
the first part says about primates which are born with.....the second part is just parallel to the first one, human is born with. D is perfect

Also, {B} has SVA error.. check out the non-underlined part after the underlined.. "consists" .. we need cranium.
So, {D}
