What type of information do nonrestrictive phrases and clauses provide?

Essential details for understanding.
Information that is essential to the main idea.
Incidental information that adds context.
None of the above.

The correct answer is: Incidental information that adds context.

Nonrestrictive phrases and clauses provide incidental information that adds context to the main idea without altering its fundamental meaning. These elements are often set off by commas and are used to enhance the reader's understanding by offering extra details. Importantly, the core message remains clear even if the nonrestrictive clause is removed. This characteristic distinguishes them from restrictive clauses, which are necessary for the complete understanding of the sentence because they provide essential details that define or limit the subject they refer to.
