Preview: Explanations
1."must"(a)
Use 'must have + past participle' for a strong past deduction. Crying for hours is strong evidence that she was very upset. 'Might have' would express uncertainty, but the evidence here is convincing.
2."have to"(b)
Use 'have to' for external obligations, especially legal requirements. The law makes wearing a helmet compulsory. 'Should' and 'ought to' are too weak for legal requirements.
3."might"(c)
Use 'might have + past participle' to express a possible past explanation. 'Probably' suggests reasonable possibility but not certainty. If the speaker were certain, 'must have' would be correct, but 'probably why' shows speculation.
4."should have remembered"(d)
Use 'should have + past participle' to express regret about a past action. They didn't book in advance, and the consequence was no rooms available. The speaker regrets not remembering to book.
5."Could"(a)
Use 'Could you...?' to make a polite request. It is softer and more polite than 'Can you...?' and much more natural than 'Must you...?' (which implies annoyance) or 'Should you...?' (which questions appropriateness).
