which kinds of punctation are used to set off nonrestrictive clauses? select the two correct answer/

dashes
quotes
parenthese
periods
colons

To set off nonrestrictive clauses, also known as nonessential clauses, the correct punctuation marks are:

- Commas
- Parentheses

Nonrestrictive clauses are additional pieces of information that can be removed from a sentence without altering its basic meaning. Commas are commonly used to enclose these clauses. Parentheses can be used as well for additional or explanatory information that is seen as less directly related to the main sentence.

Dashes can also be used to set off nonrestrictive information; they have a similar function to commas and parentheses but are often used for emphasis or to make a break in the sentence more pronounced. However, dashes were not included in the options provided, so the most accurate answers based on the given options are commas and parentheses.
