I had a very difficult time figuring out how to best approach this problem. Normally, I am initially able to read the sentence and flag/classify the grammar error. With this question, however, I had a very difficult time eliminating incorrect answer choice because I felt that "Unlike" phrase was the correct way to begin the sentence. I would appreciate the forums incite into how they best eliminated incorrect answer choices to arrive at the best choice. Thanks!
Unlike most warbler species, the male and female blue-winged warbler are very difficult to tell apart.
a. Unlike most warbler species, the male and female blue-winged warbler are very difficult to tell apart.
b. Unlike most warbler species, the gender of the blue-winged warbler is very difficult to distinguish
c. Unlike those in most warbler species, the male and female blue-winged warblers are very difficult to distinguish
d. It is very difficult, unlike in most warbler species, to tell the male and female blue-winged warbler apart.
e. Blue-winged warblers are unlike most species of warbler in that it is very difficult to tell the male and female apart.
Though I think I will go for E, due to the following reasons:
Idiom is : Unlike X,Y ... where X and Y are Nouns / Noun Phrase. ( not Preposition Phrase )
Option A - Incorrect comparison ( Comparing Most Species to Male and Female Warbler )
Option B - Incorrect comparison ( Comparing most species to Gender )
Option C - Incorrect Comparison ( Comparing Those to Male and Female Warblers)
Option D - Incorrect usage of Unlike Idiom ( Preposition Phrase )
Option E - Correct comparison and Idiom
Rewritting Option E :
unlike most species, Blue-winged warblers are of warbler in that it is very difficult to tell the male and female apart.
This correctly indicates the Idiom usage ( which is perfect )
