Put the verb in brackets into the correct tense to form conditionals in the full form. The constructors _______ (build) the road if they had had enough tools.

The correct answer is **would have built**. This is a type 3 conditional. Conditional sentences type 3 describe hypothetical situations in the past, i.e. situations that did not happen. We use "if + past perfect, would have + past participle". * If they had had enough tools, they would have built the road. Перевод на русский: Правильный ответ: **would have built**. Это условное предложение третьего типа. Условные предложения третьего типа описывают гипотетические ситуации в прошлом, то есть ситуации, которые не произошли. Мы используем структуру "if + past perfect, would have + past participle". * Если бы у них было достаточно инструментов, они бы построили дорогу.
