Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending read this sentence. it contains a comma splice. this coffee shop is popular, the line is always long. which of the following makes this sentence correct? this coffee shop is popular the line is always long. this coffee shop is popular; and the line is always long. this coffee shop is popular: because the line is always long. this coffee shop is popular. the line is always long.

Explanation:

• First option: Removing the comma but not adding proper punctuation (like a period or semicolon) creates a run - on sentence, so it's incorrect.
• Second option: Using a semicolon with "and" is incorrect. A semicolon is used to separate two independent clauses without a coordinating conjunction (or the conjunction should be used without the semicolon in this case).
• Third option: A colon should not be used before "because" as "because" introduces a subordinate clause, and the relationship here is not one that a colon is appropriate for (colons are used for explanations, lists, etc., not for introducing subordinate clauses).
• Fourth option: Splitting the two independent clauses into two separate sentences with a period is a correct way to fix a comma splice.

Answer:

D. This coffee shop is popular. The line is always long.
