Explanation
Correct answer: C.
Choice C is the best answer. “For example” logically signals that the following information about Ky—that she once shaped her hair to look like Africa—is an example supporting the previous statement that she makes different shapes with her hair.
Why the other choices are wrong
Choice A
Choice A is incorrect because “soon” illogically signals that the event described in this sentence occurred soon after the statement about Ky making different shapes with her hair. Instead, the sentence provides an example of one of these shapes.
Choice B
Choice B is incorrect because “elsewhere” illogically signals that the event described in this sentence occurred in a different place than the statement about Ky making different shapes with her hair. Instead, the sentence provides an example of one of these shapes.
Choice D
Choice D is incorrect because “however” illogically signals that the information in this sentence contrasts with the statement that Ky makes different shapes with her hair. Instead, the sentence provides an example of one of these shapes.
