A diatribe is a rant or verbal attack, the same as a tirade. Therefore, look for the answer choice with synonyms. In choice (A), a torrent is a surge or violent flow, not a trickle. In choice (B), sophistry means a lack of imagination or lack of creativity. In choice (C), stalwart means strong and muscular, not feeble. Choice (D) is the only pair that contains synonyms.
