Explanation

When using a list of three or more things in a sentence, a comma must be placed between each item of the list.

safe food, adequate shelter, or clean water.

Explanation

Every time there is a list of three or more things in a sentence, those things must be separated by commas, conjunctions, or both.

Jane Sally, and Suzy all went to the zoo together

The Mongols or the Huns and the Parthians

Explanation

When using a list of three or more things in a sentence, a comma must be placed between each item of the list. Note that the comma near the conjunction should precede the conjunction, rather than following it. The best way to write the underlined portion of the above sentence is, "The Mongols, the Huns, and the Parthians."

10

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.

I like to go camping fishing and hiking, but I just don't have the time.

I like to go camping, fishing, and hiking, but

I like to go camping fishing and hiking, but

I like to go camping fishing, and hiking, but

I like to go, camping fishing and hiking, but

I like, to go camping, fishing and hiking, but

Explanation

Whenever you have a list of things in a sentence, each item on the list—whether they are nouns, verbs, phrases, etc.—must be separated by commas. Therefore, "I like to go camping, fishing, and hiking, but" is the best way to construct the first part of this sentence. After all, "camping," "fishing," and "hiking," are all separate grammatical items.
