Question

if necessary, add or remove commas from the sentence.
context: i have more than one cousin.
my cousin, wendy corduroy, likes to design and fly kites.

Explanation:

The context states there are multiple cousins, so "Wendy Corduroy" is essential information to identify which cousin is being discussed. Essential restrictive clauses/identifiers do not use commas around them.

Answer:

My cousin Wendy Corduroy likes to design and fly kites.
