Statements : Some books are tables. Some tables are mirrors. Conclusions : I. Some mirrors are books. II. No book is mirror.

The correct answer is: Only conclusion I follows.

The first statement is “Some books are tables.” This means that there exists at least one book that is also a table. The second statement is “Some tables are mirrors.” This means that there exists at least one table that is also a mirror.

From these two statements, we can conclude that there exists at least one book that is also a mirror. However, we cannot conclude that all books are mirrors, or that all mirrors are books. Therefore, only conclusion I follows.

Here is a more detailed explanation of each option:

• Option A: Only conclusion I follows. This is the correct answer. As explained above, we can conclude that there exists at least one book that is also a mirror. However, we cannot conclude that all books are mirrors, or that all mirrors are books.
• Option B: Only conclusion II follows. This is incorrect. We cannot conclude that no book is a mirror, because the statements do not tell us anything about all books.
• Option C: Either I or II follows. This is incorrect. We cannot conclude either conclusion, because the statements do not tell us enough information.
• Option D: Neither I nor II follows. This is the correct answer. As explained above, we cannot conclude either conclusion.
• Option E: Both I and II follow. This is incorrect. We cannot conclude both conclusions, because the statements do not tell us enough information.
