Questão 3168148

The phrase is a rhetorical question, so the grammatical rules of a direct question don't apply.

The sentence is in the past tense, so both pronouns should be changed to reflect that, “Whom rescued whom?”

The slogan is an interrogative sentence and must have a noun or proper noun as its subject, not a pronoun.

The first pronoun, “Who”, is the subject and is correctly in the nominative case, but the second pronoun, “Who”, is the object and should be in the accusative case, making the correct form, “Who rescued whom?”

The slogan is grammatically incorrect because it uses a subject pronoun where an object pronoun is needed, but the phrase is a rhetorical question that intentionally uses the informal “who” to emphasize the shared identity of the rescuer and the rescued.
