Question

recycling is as easy as sorting your throw - away items into separate bins and taking them out with the trash. it is also one of the easiest ways that you can reduce the negative impact humans have on the planet. every ton of paper that is recycled instead of thrown in the trash reduces the amount of pollution that goes into the air. in fact, it saves our atmosphere from pollutants that equal eight months worth of exhaust fumes from a car. aluminum cans are 100% recyclable. an empty soda can is able to be recycled and put back on the shelf as a brand new soda can two months after you recycle it. but people recycle less than 50% of aluminum cans. recycling is easy and it makes a big difference. aluminum cans choose one option a are completely recyclable. b create pollutants like car exhaust fumes. c are only 50% recyclable. d take two months to break down.

Explanation:

The text states "Aluminum cans are 100% recyclable." 100% recyclable means completely recyclable. Option B is incorrect as it's the pollution from not recycling paper that's compared to car exhaust, not aluminum cans creating such pollutants. Option C is wrong because it's the recycling rate of aluminum cans by people (less than 50%) that's mentioned, not the recyclability of the cans themselves. Option D is incorrect as it's about an empty soda can being recycled and back on the shelf as new in two months, not breaking down.

Answer:

A. are completely recyclable.
