Answer 1

1. melts; will rise (после if мы ставим Present Simple, далее идёт Future Simple).
2. don’t stop; will change (после if мы ставим Present Simple, далее идёт Future Simple).
3. don’t restore; will not leave (после if мы ставим Present Simple, далее идёт Future Simple).
4. plant; will reduce (после if мы ставим Present Simple, далее идёт Future Simple).
5. don’t educate; will destroy (после if мы ставим Present Simple, далее идёт Future Simple).
6. will disappear; don’t protect (здесь главная часть будет до if, поэтому ставим future simple. После if идёт придаточная часть. Её мы оформляем во времени present simple).
7. don’t begin; won’t have (после if мы ставим Present Simple, далее идёт Future Simple).
