Задание 4. Укажите сложное предложение, в котором неверно расставлены знаки препинания.
1) Сьплет дождик большие горошины, рвется ветер, и даль нечиста.
2) Поиграл ветер с липой, подобрался к туче, дунул и брызнула гуча, и сразу разошлась дождем.
3) Я шел, приближался к лесам, и горы вырастали все мрачней и величавее, Ив пролеты между их вершинами
валился густой туман.​
