Preview: Explanations
1."get"(a)
After 'by the time' for future reference, use present simple. 'By the time' means 'before or when a certain moment arrives'.
2."understand"(b)
After 'once' in a time clause, use present simple. 'Once' means 'as soon as' or 'after'. This sentence expresses a general truth.
3."have finished"(c)
Present perfect 'have finished' is used in the time clause to emphasise that the reading will be fully completed before the lending. No future forms (will) are allowed in time clauses.
4."will come"(d)
This is a noun clause (indirect question: 'When will she come back?'), not a time clause. In noun clauses, use the future tense 'will'. Compare: 'Call me when she comes back' (time clause = present simple).
5."rises"(a)
After 'once' for future reference, use present simple. Third person singular requires 'rises'.
