Решение:

Это упражнение на выбор правильной формы глагола 'to be' (are, is) и вспомогательного глагола 'do' (do, does) для образования Present Simple и Present Continuous.

1. Where are you? What are you doing?
   Объяснение: Используем 'are' для 'you' во временах Present Continuous и Present Simple.
2. Do you doing exercises?
