Question

lekeshia, whom you met last week, is my second cousin. restrictive nonrestrictive no added clause

Explanation:

A nonrestrictive clause provides extra, non - essential information and is set off by commas. In the sentence “LeKeshia, whom you met last week, is my second cousin”, the clause “whom you met last week” gives additional info about LeKeshia and is non - essential (removing it doesn't change the core meaning of identifying LeKeshia as the second cousin). A restrictive clause is essential for identifying the noun and isn't set off by commas. So this is a nonrestrictive clause.

Answer:

nonrestrictive
