Preview: Explanations
1."might"(b)
'Might' expresses possibility — cancellation is not certain, just possible. The sentence 'It depends on how heavy the rain is' makes it clear that cancellation is uncertain. In the first conditional, the result clause can use 'might' instead of 'will' for uncertain outcomes.
2."can"(a)
'Can' in the result clause expresses permission. 'If you finish early, you can leave' = you are allowed to leave.
3."call"(b)
This uses an imperative (command) in the result clause. 'Call 999' is a direct instruction — no subject is needed.
4."am"(c)
'Going to' can replace 'will' in the result clause to express a planned intention: 'I am going to buy'. It suggests the decision is already made.
5."should"(a)
'Should' in the result clause gives advice: 'you should see a doctor'. It's softer than 'must' and appropriate for friendly suggestions.
