Although they are not considered the most highest evolved of the cepha

Although they are not considered the most highest evolved of the cephalopods, cuttlefish are extremely intelligent.

A. the most highest evolved - WRONG. Redundant due to 'most' and 'highest'.
B. the more higher evolved - WRONG. Original sentence means to state a general act of all cephalopods, so usage of comparative adjective instead of superlative form is wrong. Also redundant.
C. the most highly evolving - WRONG. 'Evolving' is a wrong modifier used to modify cephalopods.
D. the most highly evolved - CORRECT. Adverb 'highly' correctly used to lay stress on degree of evolution of cephalopods and modifies evolved.
E. the most evolutionarily high - WRONG. Meaning change due to adverb evolutionarily. It should remain as a noun to communicate proper meaning.

IMO Answer D.

Although they are not considered the most highest evolved of the cephalopods, cuttlefish are extremely intelligent.

A. the most highest evolved - either the most or the highest is the correctly used for the superlative comparison
B. the more higher evolved - it should the superlative comparison (the most), not more here
C. the most highly evolving
D. the most highly evolved - CORRECT
E. the most evolutionarily high - high is adjective here, while evolutionarily is the adverb which modifies verb - incorrect

Therfore D is the correct answer choice.

comparison and idiom error
usage of most over more and evolved over evolving is correct leaves with A & D ; amongst them option D is correct with usage of highly
IMO D:
the most highly evolved

Imo. D

Although they are not considered the most highest evolved of the cephalopods, cuttlefish are extremely intelligent.

Split 1: More vs most: more is used for comparison of two entities and most is being used for more than 2 entities. Here, cuttlefishh are extremely intelligent, means they are compared with among all species of cephalopods. Hence, most is correct. Two comparatives can not go together. Hence, B is out.

Split 2: Evolved and evolving: ing modifier immediately after refers to the relevant noun or action of the preceding clause (if followed by comma), however option C, ing modifier refers back to adverb, i.e. highly. Hence, C is wrong.


A. the most highest evolved - Two superlatives are never goes together, hence wrong
B. the more higher evolved - Incorrect as per split 1
C. the most highly evolving - Incorrect as per split 2
D. the most highly evolved - no error, seems fine.
E. the most evolutionarily high - idiom error

A. the most highest evolved
most used with highest is incorrect.

B. the more higher evolved
more used with higher is incorrect.

C. the most highly evolving
simple past should be used instead of continuous.

D. the most highly evolved

redundant usage. Dropping "evolved" changes the meaning.

IMO D

Although they are not considered- displays or introduces contrast.
The usage of highest is incorrect superlatives are used to compare when there are more than two to compare. This leaves us with B,C, D and E. The use of comparative higher is incorrect as there is no comparison.

In option C the use of present participle evolving is incorrect.

Option D the correct use of tense as well as meaning conveyed hence no error.
E changes meaning

Official Explanation

Correct Answer: D

Choice a uses a double superlative, combining most and a modifier with -est. Choice b uses a double comparison as well, using more and a modifier with -er.
Choice c incorrectly uses evolving instead of evolved, changing a modifier to a verb and making the sentence illogical. Choice e makes evolutionarily an adverb, which creates an awkward and unclear sentence.
