Which of the following is incorrect about proper use of parentheses? A. Parentheses are used to set off structurally independent elements. B. Parentheses are used to enclose text within other parentheses C. Parentheses are used introduce an abbreviation in the text D. Parentheses are used to set off in-text citations

B. Parentheses are used to enclose text within other parentheses.

Explanation:

Parentheses possess certain rules that govern it's use.

Rule 1: Use parentheses to enclose information that clarifies or is used as an aside.

For Example:

1. He finally answered (after taking five minutes to think) that he did not understand the question.

2. He gave me a nice bonus ($500).

It is important to note that the use of parentheses indicates that the writer considered the information less important—almost an afterthought.

Rule 2: Periods go inside parentheses only if an entire sentence is inside the parentheses.

This is a rule with a lot of wiggle room. An entire sentence in parentheses is often acceptable without an enclosed period:

For Example:

1. Please read the analysis. (You'll be amazed.)

2. Please read the analysis (you'll be amazed).

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
