I will say the example sentence sounds like the TOWL, and if you were told specifically that it would be given, there’s not much reason to give another, similar test. Regardless, one is not typically supposed to accept answers that simply quote the word, which is what all his responses did. These are essentially the same as, “‘Word’ is a word.” Which doesn’t meet the task objectives. Well, actually, that one does! But if the stimulus word were anything else, it wouldn’t.
