Question

Statements: Some inputs are outputs.
All outputs are necessary.
No necessary is a result.
Conclusions: I. All inputs being necessary is a possibility.
II. All results being inputs is a possibility.

• A. if only conclusion I follows.
• B. if only conclusion II follows.
• C. if either conclusion I or conclusion II follows.
• D. if neither conclusion I nor conclusion II follows.
• E. if both conclusion I and conclusion II follow.

Answer 1

The correct option is C if either conclusion I or conclusion II follows.

There are three cases possible.

All inputs can be necessary.

This is a possibility but not always true.

All results can be necessary.

This is a possibility but not always true.

Only one diagram at a time is possible.

Thus either conclusion I or II is correct.

Hence, Option C is correct.
