2. All instruments are bagpipes.

This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
All guitars are bagpipes.

Logical Deduction from Statements

We are given two statements:

  • Statement 1: All guitars are instruments.
  • Statement 2: All instruments are bagpipes.

We need to determine which conclusion logically follows from these statements.

Analyzing the Statements

Statement 1 establishes a relationship where the set of 'guitars' is entirely contained within the set of 'instruments'.

Statement 2 establishes a relationship where the set of 'instruments' is entirely contained within the set of 'bagpipes'.

Deriving the Conclusion

This situation follows the principle of transitivity in logic. If all members of group A are also members of group B, and all members of group B are also members of group C, then it logically follows that all members of group A are also members of group C.

Applying this:

  • Guitars (A) are Instruments (B).
  • Instruments (B) are Bagpipes (C).

Therefore, based on transitivity:

  • All Guitars (A) are Bagpipes (C).

Evaluating the Options

Let's examine the provided options based on our derived conclusion:

  • Option 1: All bagpipes are instruments. (Incorrect - This is the converse of Statement 2).
  • Option 2: All instruments are guitars. (Incorrect - This is the converse of Statement 1).
  • Option 3: All guitars are bagpipes. (Correct - This matches our derived conclusion).
  • Option 4: No guitar is a bagpipe. (Incorrect - This contradicts our conclusion).

The conclusion that logically follows from the given statements is that all guitars are bagpipes.
