Whereas in mammals the tiny tubes that convey
nutrients to bone cells are arrayed in parallel lines, in
birds the tubes form a random pattern.

(A) Whereas in mammals the tiny tubes that convey
nutrients to bone cells are arrayed in parallel
lines, in birds the tubes

(8) Whereas the tiny tubes for the conveying of
nutrients to bone cells are arrayed in mammals
in parallel lines, birds have tubes that

(C) Unlike mammals, where the tiny tubes for
conveying nutrients to bone cells are arrayed in
parallel lines, birds' tubes

(D) Unlike mammals, in whom the tiny tubes that
convey nutrients to bone cells are arrayed in
parallel lines, the tubes in birds

(E) Unlike the tiny tubes that convey nutrients to
bone cells, which in mammals are arrayed in
parallel lines, in birds the tubes

OA A

I chose A because a bird is a mammal... then i remembered that a bird is in fact NOT mammal, but it's a good thing I thought that for this question otherwise I would have gotten it wrong hahaah

IMO A.
Rest all makes illogical comparisons.

looks llel and no grammitical error

the tiny tubes are compared with birds....faulty comaprison

IMO A is correct

Couple of questions..

Though the best answer is A, Doesnt "whereas" in the beginning make the sentene look awkward?

If option D was,
Unlike mammals, in whom the tiny tubes that
convey nutrients to bone cells are arrayed in
parallel lines, the birds' tubes

then would it be right?

Hi Expert,
I need to compare apple to apple or orange to orange, not apple to orange or orange to apple, as far i know. So, in E, 'tiny tubes' is compared with 'bird's tiny tubes'. Most of us think that the first 'tiny tubes' may be ALL 'tiny tubes' in this world, and the 2nd 'tiny tubes' is only IN birds. So, 'tiny tubes' in ALL and 'tiny tubes' in BIRDS are not the SAME thing; the comparison is NOT so sweet. So, if this the case, then in A, I think that 'tiny tubes' in MAMMALS and 'tiny tubes' in BIRDS are not the SAME thing at all! So, we can cross out choice A, too.

. Do you think these two 'tiny tubes' are the SAME things, expert?

Actually, what SHOULD we compare here? Should we compare just 'MAMMALS' with 'BIRDS' or 'tiny tubes' with 'tiny tubes'?
In apparently, it seems that we're comparing JUST 'apple' with 'apple', we're NOT comparing ONLY 'apple' with 'apple'; we're comparing the first 'apple', which comes from 'apple tree', with the 2nd 'apple', which MUST come from 'apple tree' too. If the 2nd 'apple' comes from 'orange tree', then it is NOT pure comparison

,too. If THIS is true, then 'tiny tubes' IN MAMMALS and 'tiny tubes' IN BIRDS does not make pure comparison at all.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
