Решение
- Действие произошло раньше другого прошедшего действия (before the mayor arrived), значит нужен Past Perfect: had planted.
- После so that в прошедшем контексте используется would/could: could have (a safer habitat).
- В придаточном времени после when будущее не используется, нужен Present Simple: gets.
- Условное предложение
-го типа: в условии Present Simple: pollute. - Согласование времён в косвенной речи: would become.
- Причина предшествует состоянию облегчения в прошлом, нужен Past Perfect: had cleaned up.
- Косвенная речь, в условии Past Simple (continued): would become extinct.
- В косвенной речи Present Continuous переходит в Past Continuous: were melting.
- В косвенной речи Present Perfect переходит в Past Perfect: had cleaned up.
💡 Почему так
В придаточных времени и условия после when и if будущее время не ставится. В косвенной речи после глагола в прошедшем времени происходит сдвиг времён: Present Continuous → Past Continuous, Present Perfect → Past Perfect, will → would.
