Question

for the last few days ive been quite sick. ive barely gotten out of bed. ive just been lying around coughing and sneezing. however, when my grandma and grandpa heard that i was sick, they came over at the drop of a hat. what is the meaning of the underlined idiom?
☐ instantly
☐ slowly
☐ hesitantly
☐ successfully

Explanation:

The idiom "at the drop of a hat" means to do something immediately or without hesitation. In the context, when the grandparents heard the speaker was sick, they came over right away. Among the options, "instantly" matches this meaning. "Slowly" and "hesitantly" are the opposite of immediate action, and "successfully" is irrelevant to the speed of their action.

Answer:

A. instantly
