Some iron are steel.

Conclusions:

• A. Only conclusion (Il) follows.
• B. Only conclusion (I) follows.
• C. Neither conclusion (1) nor (Il) follows.
• D. Both conclusions (I) and (II) follow.

Answer 1

Answer:

C. Neither conclusion (1) nor (Il) follows.

Statements:

1. Some metals are iron.

2. Some iron are steel.

Conclusion I: Some metals are steel.

This does not definitely follow.
The “some iron” in statement 2 may be different from the “some metals” in statement 1.

Does not follow.

Conclusion II: All steel are iron.

From “Some iron are steel”, we cannot conclude that all steel are iron.

Does not follow.

Answer: Neither conclusion I nor II follows.
