Explanation
Correct answer: C.
Choice C is the best answer. "What’s more" logically signals that this sentence introduces an additional aspect of Wadud’s poem beyond what was previously discussed. While the previous sentence establishes that Adnan’s painting has inspired "the poem’s exploration of temporality and identity," this sentence provides a separate, additional claim about the poem: that it reflects on poetry’s relationship to other art forms.
Why the other choices are wrong
Choice A
Choice A is incorrect because "in other words" illogically signals that the information in this sentence is a paraphrase or restatement of the previous point about how Adnan’s painting has inspired "the poem’s exploration of temporality and identity." Instead, the sentence provides a separate, additional claim about the poem.
Choice B
Choice B is incorrect because "for instance" illogically signals that the information in this sentence supports the previous point about "the poem’s exploration of temporality and identity" by providing an example. Instead, the sentence provides a separate, additional claim about the poem.
Choice D
Choice D is incorrect because "conversely" illogically signals that the information in this sentence is contrary to the previous point about how Adnan’s painting has inspired "the poem’s exploration of temporality and identity." Instead, the sentence provides a separate, additional claim about the poem.
