Can anyone explain Option E is it incorrect cos it changes the intended meaning of the sentence?
Like the color-discriminating apparatus of the human eye,
insects’ eyes depend on recording and comparing light intensities in three regions of the electromagnetic spectrum.
(E) that of an insect’s is dependent on the
E is incorrect because you cannot say
" that of an insect’s": it's a "double" possessive. You can say (generally speaking) " that of an insect" or "insect's" to express possession, but you cannot use both. Moreover "That" should point to "apparatus " and E looks like this:
(E) that(apparatus) of an insect’s is dependent on the you want to compare the apparatus of the eye (not of the insect in general).
Example: you want to compare the size of the moon to something, you can say "like that of the moon" or "like the moon's": "like that of the moon's" is incorrect.
D)that of an insect’s eye == that of an eye of an insect. Here the double possessive is fine because the last one (insect’s) refers to the eye, where in E(and in my example) both forms pointed to the same thing.
Hope it's clear
