Answer 2

1. Take a piece of natural silk fabric and another piece of artificial silk fabric.
2. Burn both the fabrics separately and observe the smell produced.

Conclusion:
1. The fabric which burns giving a smell of burning hair will be natural silk or pure silk.
2.  The fabric which burns giving a smell of burning paper will be artificial silk.
 
Just like silk, wool is also made up of proteins. So, a piece of woollen fabric also burns giving the smell of burning hair.
