Someone plz help me! :(

which speech are you talking about?

i'm pretty sure i had this question the other day and b was the right answer.

from the political point of view it could be said that the candidate   is an effective speaker because she takes a strong position on the issue. it is an open discussion but probably she is making a presentation and can choose which subjects she wants to address. she is very likely to attain her aim which is to convince voters to accept her proposal.
