With reference to polyethylene terephthalate, the use of which is so widespread in our daily lives, consider the following statements:1.Its fibres can be blended with wool and cotton fibres to reinforce their properties.2.Containers made of it can be used to store any alcoholic beverage.3.Bottle made of it can be recycled into other products.4.Articles made of it can be easily disposed of by incineration without causing greenhouse gas emissions.Which of the statements given above are correct?

1. A

   1 and 3

   1 and 3. PET fibre blends with cotton/wool; bottles are widely recycled. Not for every alcoholic beverage; incineration still emits CO2.

2. B

   2 and 4

   2 and 4. Both over-claim.

3. C

   1 and 4

   1 and 4. Incineration is not GHG-free.

4. D

   2 and 3

   2 and 3. Alcohol compatibility is not universal.

Summary. Official key is (a) 1 and 3. PET (polyethylene terephthalate) fibres are blended into fabrics; bottles are recycled into fibre and new packaging. It is not a blanket alcohol-storage plastic, and burning it produces greenhouse gases.
