Bo: _①_ my phone in my chest pocket?
Dr. J: Right.
Dr. J. You’ll get tumors in your chest. Not in your pants pocket either.
Bo: And headphones?
Dr. J:_ ②_them; don’t hold a phone near your head–nor a tablet or laptop on your lap.
Answer And Explanation:
① ‘Put‘ is the answer; though ‘have’ is okay, the emphasis in a “dos and don’ts” situation is usually on the beginning action, or the doing. In other words, we put something in a place before we have it in that place. So the ‘putting’ is a the “beginning” or causal action. Also, if you imagine a patient in a doctor’s office–after a physical exam– s/he probably puts the phone in his or her pocket in front of the doctor. So, the doctor’s saying “don’t do that” refers to something the person is “doing”, not “having.”
② ‘Use’ is the answer; there is no other sensible choice, here.
