2 Natural rubber has low ten-stile strength
Vulcanized rubber has high ten-stile strength.
3 Natural rubber is low elasticity
Vulcanized rubber is high elasticity. 

Answer 2

natural rubber
*it is soft and sticky
*it has low tensile strength
*it has low elasticity
*it can be used over a narrow range of temperature.
*it has low wear and tear resistance
*it is soluble in solvents like ether,carbon tetrachloride , petrol etc...

Vulcanised rubber
*it is hard and non-sticky
*it has high tensile strength
*it has high elasticity
*it can be used over a wide range of temperature
*it has high wear and tear resistance
*it is soluble in all common solvents
