Question

find the appositive. if it is nonrestrictive, set it off with commas. if it is restrictive, submit the text without making any changes.
muslims, christians, and jews coexisted in relative peace after the moors conquered spain. the golden age of tolerance the name sometimes given to this era lasted for several hundred years.

Explanation:

An appositive is a noun or noun phrase that renames another noun right beside it. In the sentence "The Golden Age of Tolerance the name sometimes given to this era lasted for several hundred years", "the name sometimes given to this era" renames "The Golden Age of Tolerance". Since it is nonrestrictive (providing additional, non - essential information), we set it off with commas.

Answer:

The Golden Age of Tolerance, the name sometimes given to this era, lasted for several hundred years.
