对不起，抄错了，sorry：第四句：：：we（不是my） delayed the meeting，in order that we could settle the tense situation】

答案

People complained that the local government hadn't solved the pollution problem properly. 

As long as you have made great efforts, nobody will blame you even if you fail in the future.

He told me to take it easy, and I didn't have to complete the work in advance/ahead of time.

I put off the meeting in order to deal with the tense situation.
