Compared to alligators, crocodiles are better able to tolerate high sa

Aha!!! I read C again -- "compared to alligators crocodiles are MORE tolerant of high salinity". Correct form should be -- "compared to alligators crocodiles are tolerant of salinity.". That should rule out C. And based on elimination I would pick D. But, still if someone can throw light on the semi-colon issue, that will be fantastic.....

learning it, one step at a time.

Compared to alligators, crocodiles are better able to tolerate high salinity, because, unlike alligators, the glands on crocodiles' tongues can expel salt.

A. Compared to alligators, crocodiles are better able to tolerate high salinity, because, the glands on crocodiles' tongues can expel salt- Alligators Vs Tongues not acceptable
B. Unlike alligators' tongues, salt can be expelled through the glands on crocodiles' tongues, making crocodiles better than alligators at tolerating high salinity-Tongues Vs Salt comparison
C. Salt can be expelled through the glands on crocodiles' tongues and not through those on alligators' tongues; therefore, compared to alligators, crocodiles are more tolerant of high salinity-Redundant long sentence and passive voice-rejected
D. Unlike alligators, crocodiles can expel salt through the glands on [quot Logical[/quote]tongues; crocodiles are thus more tolerant of high salinity than are [b]alligators-Logical Comparison- Accepted
[/b]E. Compared with alligators, crocodiles are better at tolerating high salinity, because they can expel salt through the glands on their tongues while alligators' tongues cannot

Compared to alligators, crocodiles are better able to tolerate high salinity, because, unlike alligators, the glands on crocodiles' tongues can expel salt.

A. Compared to alligators, crocodiles are better able to tolerate high salinity, because, unlike alligators, the glands on crocodiles' tongues can expel salt - Incorrect comparison.
B. Unlike alligators' tongues, salt can be expelled through the glands on crocodiles' tongues, making crocodiles better than alligators at tolerating high salinity - Incorrect comparison.
C. Salt can be expelled through the glands on crocodiles' tongues and not through those on alligators' tongues; therefore, compared to alligators, crocodiles are more tolerant of high salinity - Change the meaning.
D. Unlike alligators, crocodiles can expel salt through the glands on their tongues; crocodiles are thus more tolerant of high salinity than are alligators - Awesome.
E. Compared with alligators, crocodiles are better at tolerating high salinity, because they can expel salt through the glands on their tongues while alligators' tongues cannot - compare to/compare with are generally used with quantities/statistics.

Can someone help me understand the problem with option "E" here ?

In option E, " they can expel salt through the glands on their tongues while alligators' tongues cannot", the comparison is incorrect and neither does it make sense logically when you read the italicized portion.
The option is saying - crocodiles can expel salt.... while alligators' tongues cannot. Not the right comparison.
Hope I was clear.

COMPARISONS, PRONOUNS



A. Compared to alligators, crocodiles are better able to tolerate high salinity, because, unlike alligators, the glands on crocodiles' tongues can expel salt ----------- second comparison is not parallel: "unlike alligators" is incorrectly being compared to "the glands".


B. Unlike alligators' tongues, salt can be expelled through the glands on crocodiles' tongues, making crocodiles better than alligators at tolerating high salinity ---------- wrong comparisons: "alligator's tongues" is being compared to "salt".


C. Salt can be expelled through the glands on crocodiles' tongues and not through those on alligators' tongues; therefore, compared to alligators, crocodiles are more tolerant of high salinity ---------- Pronoun "those" is ambiguous, as it could refer either to "glands" or to "tongues".


D. Unlike alligators, crocodiles can expel salt through the glands on their tongues; crocodiles are thus more tolerant of high salinity than are alligators ------ CORRECT


E. Compared with alligators, crocodiles are better at tolerating high salinity, because they can expel salt through the glands on their tongues while alligators' tongues cannot -------- Pronoun "they" is ambiguous, as it could refer either to "alligators" or to "crocodiles".

Option D

Tolerant of or Tolerant to ?

Idiomatically ?

I am not too sure about tolerant to but tolerant of is correct.

It may not be the best strategy to rely heavily on idioms for GMAT SC.

Always TOLERANT + OF, never TOLERANT + TO

However, when using the word tolerance, both TOLERANCE + OF and TOLERANCE + FOR is accepted.


I second what the previous poster mentioned. Idioms are complementary in SC, so if you can work your sentence with other splits, do so. There are few questions in which idioms play a decisive role.

svd11 "Tolerant of" is a fairly standard expression. "Tolerant to" is not, but more to the point, it's not offered in any of the choices. One can build up a tolerance to a medication, but that's a somewhat different meaning.
