。
She asked me if I knew her address.
Literal
She [topic-は] me [to-に] her address [object-を] know [question-か] [quotative-と] asked.
Demonstrates indirect question embedding — the clause 住所を知っているか is quoted with と and followed by 尋ねた ('asked'). Note the ambiguity of 彼女 appearing as both subject and possessive, which context resolves.
