In a group discussion which option is most clearly a clarifying question?

a. what are the reasons you question the author's professionalism.
b. what is your overall point, and how do you support it?
c. what are the author's credentials, and are they sufficient?
d. if you were the author, could you have done a better job?

Letter B. What is your overall point, and how do you support it?

In a group discussion, the rules of a healthy debate should prevail. That is, each person should feel free to expose its point-of-view, its individual understanding of the main topic, in order to develop these understandings and come up with a better one, as a group.

And so to achieve such, the most crucial point of the discussion is when each presents its overall point and the arguments that led to them.

the answer is c or the third one.

the answer is d. books are banned from the library. this is an example of censorship because the library did not want people reading the content of those books. the library censored the books by banning them.
