Conclusion for Question 1:
Given the statement "If it is Monday, then the library is closed," and the fact that "Today is Tuesday," we can conclude that the condition for the library being closed (which is Monday) is not met.
Thus, the correct response is: The library is not closed.
Conclusion for Question 2:
The statements provided are:
- If a coin is a quarter, then it is worth 25 cents.
- If a coin is worth 25 cents, then 4 would make a dollar.
However, neither of these statements allows us to conclude that having a coin necessarily implies it is a quarter or to derive any relevant conclusion regarding the nature of a coin in general.
Thus, the appropriate response for this question is: It is not possible to draw a conclusion.
