Question

1. use a colon to connect the following two independent clauses:

then, the professor asked the question all the students were dreading.
\who would like to read aloud for the class?\
then, the professor asked the question all the students were dreading. \who would like to read aloud for the class?\
then, the professor asked the question all the students were dreading: \who would like to read aloud for the class?\
then; the professor asked the question all the students were dreading: who would like to read aloud for the class?
then: the professor asked the question all the students were dreading. \who would like to read aloud for the class?\

Explanation:

To connect two independent clauses with a colon, the colon should follow the first clause (which is a complete sentence) and introduce the second clause (here, a direct question that is the "question" from the first clause). Also, the direct question should be in quotes and start with a capital letter. Let's analyze each option:

• First option: Uses a period instead of a colon, incorrect.
• Second option: The first clause ends with a colon, the second clause (the question) is in quotes with a capital "Who", correct structure.
• Third option: The question is not in quotes, incorrect.
• Fourth option: Incorrect use of colon (after "Then" which is part of the first clause, not at the end of the first independent clause), and uses a period instead of colon before the quote, incorrect.

Answer:

B. Then, the professor asked the question all the students were dreading: "Who would like to read aloud for the class?" (Note: Assuming the second option is labeled as B, as per typical multiple-choice labeling; if labels were different, adjust accordingly, but based on the options, the correct one is the second option with the colon after the first clause and the quoted question with capital "Who".)
