In this question, three statements are given followed by two conclusions. Choose the conclusion(s) which best fit(s) logically.
Statements:
1) Some newspapers are magazines.
2) All newspapers are books.
3) Some books are journals.
Conclusions:
I. Some journals are newspapers.
II. All magazines are books.
-
A.
Neither conclusion I nor II follows
-
B.
Only conclusion I follows
-
C.
Both conclusions I and II follow
-
D.
Only conclusion II follows
Correct Answer:
A. Neither conclusion I nor II follows
Explanation:
To determine which conclusion logically follows, we can analyze the relationships between the sets:1. Relationship between Newspapers, Magazines, and Books: The first statement notes that some newspapers are magazines, while the second statement specifies that all newspapers are books. This means the group of newspapers is entirely contained within the category of books. Consequently, the portion of newspapers that are magazines must also be books. However, this does not mean all magazines are books, as there could be magazines that are not newspapers. Therefore, Conclusion II (All magazines are books) is not necessarily true.
2. Relationship between Books and Journals: The third statement says that some books are journals. While we know all newspapers are books, there is no information linking journals specifically to the newspaper subset of books. The journals could overlap with a part of the book category that contains no newspapers. Therefore, Conclusion I (Some journals are newspapers) cannot be confirmed as true.Since neither conclusion can be proven based strictly on the provided statements, the correct answer is that neither conclusion I nor II follows.
