Identify the nonrestrictive clause

The clause "who won a prestigious art award last year" provides extra, nonessential information about the proper noun "Adriana." Because the sentence remains grammatically complete and retains its core meaning without this clause, it is a nonrestrictive relative clause. Using the Nonrestrictive Clauses knowledge point, we know that nonrestrictive information must be set off from the rest of the sentence using matching punctuation marks on both sides.

Evaluate parentheses punctuation

The first option uses parentheses: "Adriana (who won a prestigious art award last year) is studying painting in school." Parentheses are a correct way to set off nonessential, parenthetical information. The opening and closing parentheses correctly enclose the entire nonrestrictive clause.

Evaluate incorrect dash placement

The second option states: "Adriana—who won a prestigious art award last year is studying painting—in school." This sentence incorrectly places the second em dash after "painting" instead of after "year," which breaks the logical flow and separates the prepositional phrase "in school" instead of the nonessential clause.

Evaluate comma punctuation

The third option uses commas: "Adriana, who won a prestigious art award last year, is studying painting in school." Using the Relative Clause Punctuation knowledge point, commas are the standard punctuation marks used to set off nonrestrictive relative clauses. The commas correctly frame the clause at both the beginning and the end.

Evaluate correct dash placement

The fourth option uses em dashes: "Adriana—who won a prestigious art award last year—is studying painting in school." Em dashes can be used in pairs to set off parenthetical information or emphasize a nonrestrictive clause. The dashes are placed correctly at both boundaries of the clause.

Evaluate missing punctuation

The fifth option states: "Adriana who won a prestigious art award last year is studying painting in school." This option lacks any punctuation to set off the nonrestrictive clause, which is incorrect because nonessential clauses must be separated from the main clause.
