The instructions specify ___ the machine should be cleaned after each use.
答えを見る
正解: A) that
What follows the blank is 'the machine should be cleaned after each use' — a complete clause with nothing missing. The conjunction 'that' introduces a complete clause as the object of a verb. 'What' is a relative pronoun and needs an incomplete clause after it (missing a subject or object). 'Which' and 'whose' also need something missing after them. The test is whether what follows is complete or incomplete.
