Read the following statements given by Suresh about a metal box containing some coloured beads.
1. The box rattles when shaken.
2. The box is soft.
3. The box cannot be broken easily.

A1 and 3 only
B2 and 3 only
C3 and 4 only
D1, 3 and 4 only
C

The correct answer should be C as 1 is true even when the box is not made of metal, for example glass. Thus, 1 is not concluding that it is a metal box.
