Question

Поставьте в present simple
Yana (cook) very well
They (play) football every weekend

Answer 1

Yana cooks very well

They plays football every weekend

Answer 2

Yana cooks very well.

They play football every weekend

Present Simple сам по себе очень прост. Если используется в сочетании с I, you, we, they - после глагола ничего не ставим. Если в сочетании с he, she, it - после глагола добавляем -s.

Например:

They play basketball very well;

She reads books.
