Please answer me a question? (translating classical Chinese sentences)

Many people answered the first sentence, and they were all right.

The second sentence

Take its branches and leaves as its roots, thinking that it is necessary to be open and honest.

Although we only see the branches and leaves, we can infer the roots. "Zhan" means "divination" in ancient times, and the vernacular means speculation. "I thought it was a necessary person." There is no need to explain. Compare people with trees!

The third sentence is the solo upstairs. Good idea.
