Question #N921

The 1985 film *Back to the Future* is one of the most popular and influential movies ever made, but it is not without its flaws. For example, the movie relies on the trope of time travel, which is often used to make a story more exciting. However, the movie’s use of time travel makes it difficult to create a believable story. In the end, the movie is a fun and entertaining adventure, but it is not a perfect film.

Which choice best combines the sentences at the underlined portion to create a grammatically correct and stylistically effective sentence?
A. The movie’s use of time travel makes it difficult to create a believable story; however, the movie is a fun and entertaining adventure.
B. The movie’s use of time travel, however, makes it difficult to create a believable story, but it is a fun and entertaining adventure.
C. The movie’s use of time travel makes it difficult to create a believable story, it is a fun and entertaining adventure.
D. The movie’s use of time travel, because it makes it difficult to create a believable story; it is a fun and entertaining adventure.

Correct Answer is: A

Choice A creates a grammatically correct sentence by using a semicolon to connect two independent clauses, creating a sense of contrast between the two ideas. The semicolon also separates the introductory phrase 'The movie’s use of time travel' from the rest of the sentence, making the sentence more clear and concise. Choices B, C, and D are all incorrect because they either use incorrect punctuation, like a comma splice, or they create a grammatically incorrect sentence, such as by using a comma in place of a semicolon.
