Select the correct answer from the choices given
NEGATIVES OF NEED, MUST AND TO HAVE TO
NEEDN'T (do something) means the same as "don't have to do something."
NEEDN'T HAVE (done something): something that was unnecessary was done.
"You needn't have left a tip; service is included."
DIDN'T NEED used with a noun or a verb means it wasn't necessary. It
usually (but not always) implies I didn't have the object or do the
action.
"I didn't need to buy a car so I didn't." (or "but I did.")
MUST & HAVE TO mean nearly the same in the affirmative, different
things in the negative:
MUSTN'T means "It's forbidden."
"You mustn't smoke in here; there's a "no smoking" sign."
DON'T HAVE TO is permissive. "You can if you want to."
"Saturdays, I don't have to work."(Sometimes I do, sometimes I don't.)
Note: MUST used in the past can only be used for an inference.
"I see your umbrella's wet. You must have been out in the rain."
