Good one!

A few thoughts:

--Idiom -- ability... "to" adapt, rules out B

--D and E are ruled out, b/c you want to get the comparison of wolves to coyote to be as close as possible, D and E put them too far away

--A, the noun 'coyote' is never there... it shows up as 'coyote's', therefore, the 'it' doesn't have an antecedent it is referring to.

And you are left with.. drum roll... C.

Thoughts?

A - what does IT refer to(COYOTE cant be the antecedent as its in possessive form)
B - ITS and THEIR both are used to refer COYOTE. We cannot define NOUN as SINGULAR and PLURAL at the sametime
D - ABILITY is the subject...then plural verb HAVE ENABLED not correct
E - expand THE RANGE is incorrect as we are not talking about a specific range. ITS RANGE is required

In addition, A uses EXPEND (expand is needed); The use of SUBJECT TO...ANIMALS...requires use of ANIMAL immediately after comma (so from that perspective we could also drop A/D/E)

imo C

If the original sentence contains an error, always look for REPEATERS: answer choices that repeat the error.

In A, subject seems to modify the coyote's amazing ability, implying that the coyote's ABILITY is subject to WILD-ANIMAL control efforts.
The intended meaning is that the COYOTE itself is subject to these efforts.
D and E repeat this error.
Eliminate A, D and E.

In B, have (plural) does not agree with the coyote (singular). Eliminate B.

The correct answer is C.
