Please could you check for me this: I understand you and Sara have had discussions on this, and agreed that Steve will be the full time member on this project form now one.

idk= i don't know the 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.

i would say b. good luck!
