Which of the following topics is too broad for a 10-minute speech?

A.

classes offered in interior design

B.

interior design tips for the college dorm

C.

the history of modern interior design

D.

preparing for a career in interior design

I am not too sure there is a clear answer to this question: in principle, you could hold a speech of 10 minutes on any topic, but the depth of the treatment of the topic would have to be adjusted.

I would choose answer C. the history of modern interior design: describing a history of anything requires a lot of details, and those need time.

Specifically, I find that options A and B are very easily condensed for 10 minutes: they are in any case not good options.

D. depends on whether this is just a general introduction or a very detailed, practically oriented, tutorial.
