16. Many _________ books are popular among adults these days. Which of the following options correctly completes the sentence above?

Answer: C

Explanation:

Children's books are popular among adults these days.

The term "children's" accurately describes the type of books being referred to in the context of popularity among adults. This suggests that books originally intended for children are being embraced by an adult audience.

A) children's

This option is identical to the correct answer and appropriately fills in the blank. It indicates that the books designed for children are receiving attention from adults, supporting the idea of crossover appeal in literature.

B) children

This option is incorrect because "children" does not function as an adjective to describe the books. Instead, it is a noun that fails to convey the intended meaning of books meant for children, resulting in an incomplete and grammatically incorrect sentence.

C) children's

This option is the correct answer as it properly serves as an adjective describing the books. It indicates that the books are designed for children, yet they are popular among adults, highlighting an interesting trend in reading habits.

D) children's

This option is identical to the correct answer and appropriately fills in the blank. It indicates that the books designed for children are receiving attention from adults, supporting the idea of crossover appeal in literature.

Conclusion

The choice "children's" effectively conveys the intended meaning of the sentence, indicating that books designed for children are also enjoyed by adults. Options B does not fit grammatically, while A and D, despite being identical to the correct answer, do not provide additional context. Thus, C is definitively the most appropriate choice.
