3. must

Answer 2

1. People must learn health habits.
2. I mustn't write them letters.
3. Soldiers must defend their Motherland.

Note: Both "must" and "have to" can be used to express obligation or necessity, but "must" is more direct and strong in its expression. "Have to" is often used when there are external circumstances or rules that impose the obligation. In some cases, both "must" and "have to" can be used interchangeably.
