Question

Arrange the different parts in the correct sequence to form a meaningful sentence/paragraph.
P : In emission testing, the government fixes the total amount of pollution that is acceptable to maintain a desired level of air quality.

Q : Economists argue this approach makes air pollution control more cost effective than the current practice of fixing air pollution standards and expecting all companies to pollute below these standards.

R : U.S.A. uses emission trading to control air pollution.

S : It then distributes emission permits to all companies in the region, which add up to the overall acceptable level of emission.

• A. R S Q P
• B. P R Q S
• C. Q P S R
• D. R Q P S

Answer 1

The correct option is D R Q P S

Here, RQPS is the correct solution. Sentence R introduces the main theme of emission trading, followed by sentence Q which argues for it and then sentences P and S follow with the explanation of what emission trading is actually made up. The other options do not form a logically coherent paragraph as the sequence RQPS does and therefore cannot be correct answers.
