Question

find the relative clause. if it is nonrestrictive, set it off with commas. if it is restrictive, submit the text without making any changes.
with his boundless enthusiasm and natural charisma, the actor who played walter in a raisin in the sun stole the show.

Explanation:

1. First, identify the relative clause. A relative clause starts with a relative pronoun (here, "who") and modifies a noun ("the actor").
2. Determine if it's restrictive or nonrestrictive. A restrictive relative clause provides essential information to identify the noun. Here, "who played Walter in A Raisin in the Sun" is necessary to identify which actor is being referred to, so it's restrictive. Thus, no commas are added around it.

Answer:

With his boundless enthusiasm and natural charisma, the actor who played Walter in A Raisin in the Sun stole the show.
