Question

you have to be more ___ or you will ___ drive your husband up the wall .​

Answer 1

Clearly, Ketan has to be more discreet )rather than discrete) or he'll drive his wife up the wall i.e., make her angry. Therefore, 'Ketan has to be more discreet or he'll drive his wife up the wall. ' is the correct option.

Answer 2

You have to be more careful or you will literally drive your husband up the wall

Detailed answer

You have to be more careful this word denotes that the person has to be more careful and has to take care.

• You will Literally is the most appropriate word to be used here
• As it is the most grammatically appropriate word to be used at this moment.
• Any other word for example if we use the word  "have" for the second option it doesn't mean anything and is an incorrect sentence.
• The sentence now conveys that the person has to be careful or they will really make the husband angry.
