Which choice completes the text so that it conforms to the conventions of Standard English?

A

specimen

B

type

C

examples

D

instance

Correct Answer: C

Choice C is the best answer. The sentence refers to two specific animals, so the noun referring to them must be plural ("examples").

Choice A is incorrect because "specimen" is singular. Choice B is incorrect because "type" is singular. Choice D is incorrect because "instance" is singular.
