Answer 1

Answer:

which of the following could be the list of daily specials offered two days in a row

Answer 2

If Q, R, and S are on the menu one day, the specials that must be offered on the following day will be:

→ P and T.

• It is said that when S is on the menu then Q has to be on the menu which is already given in the question. If R is on the menu in a day it cannot be included in the menu the following day therefore on the following day we cannot keep R.
• The specials that are left are P, T, and U. Now there is no condition given for the inclusion of P, hence P can be kept. It is given that when T is on the menu U has to be kept on the following day. In the question, there is no mention of T, therefore, we cannot keep U as T is not mentioned hence T is the only one after P that can be included.
