Answer: 1. A) the contents of a new textbook
2. A) What are the calorie and sodium counts for these items?
Explanation: 1. Formal discussion implies a serious attitude and a correct opinion during the discussion, when it comes to a serious matter or event, a book, etc. In this case, the topic for a formal discussion would be about a new textbook, because an informal discussion involves relaxed and even frivolous behavior and conversation, such as options B, C and D.
2. The follow-up question that best demonstrates the attention to the student's claim is the first option offered, because it directly posits the problem of the number of calories and amount of sodium, according to the student's claim. The second option offered attempts to prolong the solution of the problem in response to a student's claim, while the third option attempts to draw attention from the problem by offering an option that is similar to the option that is the cause of the student's claim. The fourth option directly questions the student's claim.
