Choice A is the best answer. The convention being tested is the use of verbs to express tense in a sentence. In this choice, the present tense verb “includes,” used in conjunction with the word “currently,” correctly indicates that the frog’s current range includes parts of northern New South Wales and southeastern Queensland. Choice B is incorrect because the past tense verb “included” doesn’t indicate that the frog’s range currently includes parts of northern New South Wales and southeastern Queensland. Choice C is incorrect because the future perfect tense “will have included” doesn’t indicate that the frog’s range currently includes parts of northern New South Wales and southeastern Queensland. Choice D is incorrect because the past perfect tense “had included” doesn’t indicate that the frog’s range currently includes parts of northern New South Wales and southeastern Queensland.
