No part of this book may be reproduced or transmitted in any form or ... COALWOOD. UNTIL I BEGAN to build and launch rockets, I didn't know my hometown.

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.
