I think the best answer will be c because everyone knows how he spends time
Can I see the sentence choices
Correct me if I'm wrong but I believe it is phrase or clause containing three or more words at the beginning or end of a sentence.
The conclusion is that in the end the park will be built even tough it is not in everybody's agenda. Some people, following Samara's proposal, are convinced of the benefits that the park would bring and work towards its construction, trying to share their point of view with other members of the community. The fact is that no one is actually against the park, parties who do not explicitly support it are just indiferent.
Therefore, there will be no opposition but only preassure made by park supporters so it will be built.
