Which of the following would probably be the most effective choice for a speech topic? a. molecular biology b. the history of democracy c. zoology in the australian outback d. the migration habits of tasmanian wombats

Explanation:

The history of democracy is the best topic, because is everybody's interest, aimed to a general community. Other options are too specific, like molecular biology or habits of Tasmanian wombats, theses topics are not general culture, so, as a speaker, probably you are not going to catch public's attention.

a. both connotative and denotative.

the answer is a.

explanation:

the clause "looking toward the south" modifies "a funnel cloud." it's not really the cloud that's "looking," but grammatically, that clause is modifying the cloud.
