GMATNinja KarishmaBQ1. Could "B" be wrong because
(1) "for the conveying...bone cells" isn't better than "that convey...bone cells"
(2) "in mammals in parallel lines" has a modification error
Q2. I see most posts mentioning the clause and its subject "Whereas tiny tubes..." need to be strictly parallel and comparable with the noun of the following clause. Is this rule valid? I learned that clauses need not be parallel to each other.
(B) is unsuitable because of multiple reasons.
- Verb form is clear and preferable since we know who is performing the action so 'that convey... is better.'
- 'in mammals in parallel lines' is confusing whether mammals are the ones in parallel lines.
- It is not necessary that clauses should have parallel structure but a comparison should be clear - what is being compared to what.
(A) Whereas in mammals the tiny tubes ... in birds the tubes ...
This is clear. We are comparing how the tubes are positioned in mammals vs in birds.
(B) Whereas the tiny tubes are ... , birds have tubes that ...
Not clear. Better would be 'Whereas mammals have tubes that ..., birds have tubes that ...' or 'Whereas the tiny tubes in mammals are ..., the tubes in birds are ...'
