When Jonah is suddenly and unexpectedly called out by his physical geography professor to explain how the warming of ocean currents due to global warming could trigger another ice age, he is required to use delivery.

This question is missing the options. I've found the complete question online. It is as follows:

When Jonah is suddenly and unexpectedly called out by his physical geography professor to explain how the warming of ocean currents due to global warming could trigger another ice age, he is required to use delivery.

a) manuscripted

b) memorized

c) impromptu

d) extemporaneous

He is required to use c) impromptu delivery.

Explanation:

Impromptu delivery is the speech given by someone without any preparation. It is common to happen in social events, when a person is asked to "say a few words". It also happens often in classrooms, when a teacher or professor has a student explain something without time to prepare in advance. That is precisely the case with Jonah. He must think and talk spontaneously, without notes.
