Directions to Solve ...
**Explanation:**
To solve this question, we need to analyze the given statements and determine which conclusions can be logically derived from them. Let's evaluate each conclusion one by one:
**Conclusion 1: Some journals are books.**
This conclusion cannot be logically derived from the given statements because there is no direct relationship established between journals and books. While it is true that some journals are calendars, there is no information provided to suggest that journals are also books. Therefore, this conclusion is not valid.
**Conclusion 2: Some calendars are papers.**
This conclusion can be logically derived from the given statements. The first statement states that all books are papers, and the third statement states that some journals are calendars. Since some journals are calendars and some journals are papers (as stated in the second statement), it can be inferred that there is an overlap between calendars and papers. Therefore, this conclusion is valid.
**Conclusion 3: Some books are journals.**
This conclusion cannot be logically derived from the given statements. While it is true that some journals are calendars and some calendars are papers, there is no information provided to suggest that journals are also books. Therefore, this conclusion is not valid.
**Conclusion 4: Some books are calendars.**
This conclusion cannot be logically derived from the given statements. Although it is true that some journals are calendars and some calendars are papers, there is no direct relationship established between books and calendars in the given statements. Therefore, this conclusion is not valid.
Since only Conclusion 2 is valid, the correct answer is option 'b) Only (2)'.
