Answer:
Step-by-step explanation:
The sentence that demonstrates correct colon usage is:
"There are several things that can help relieve sinus pain: decongestants, facial massage, and sleep."
This sentence is correct because it uses a colon to introduce a list of items that provide examples of things that can help relieve sinus pain. The colon is used to indicate that the list is about to follow.
In contrast, the other sentence, "There are several things that can help relieve sinus pain such as: decongestants, facial massage, and sleep," is incorrect. It uses a colon after the word "such as," which is unnecessary. The phrase "such as" already indicates that a list of examples will follow, so the colon is redundant in this context.
In summary, when using a colon, it is important to use it to introduce a list or to provide further explanation or clarification. It should not be used after words or phrases like "such as" or "including" that already indicate that a list is coming.
