Help the spaceship captain update her digital logbook about an annoying crew member. Choose the correct phrase to complete the sentence.

"I love our alien co-pilot Zorg, but he _____ my coffee mug! He _____ perfectly well that humans need caffeine to survive."

The correct answer is is always stealing / knows.

We use the Present Progressive with "always" (is always stealing) to complain about an annoying, repeated habit.

We use the Present Simple (knows) for the verb "know" because it is a stative verb (a state of mind) and cannot be used in the progressive form. Also, "Zorg" is singular, so the verb needs an 's'.
