Question

Read the sentence.

Answer 1

You should list the other choices if it's multiple choice but, it should be a semicolon instead of a colon.

Answer 2

Answer:

the introductory text in the sentence cannot stand alone.

Explanation:

The colon after 'including' should be removed because it is completely unnecessary. The word 'including' acts as a colon of sorts, so using both is redundant. You can either delete the colon and leave the sentence as is, or delete the word 'including' and add a colon, but not both.
