The following sentences form a paragraph. The last sentence of the paragraph is given. The rest of the sentences are numbered as P, Q, R, S and T. These five parts are not given in their proper order. Read the sentences and choose the alternative that arranges them in correct order.
P. Union Environment Minister Harsh Vardhan said due to concerted efforts by the government, the Air Quality Index of Delhi has improved during the last three years
Q. The national capital recorded its best air quality this year on Tuesday as incessant rains removed pollutants from the air
R. An official of the Central Pollution Control Board (CPCB) said rains in the last few days removed pollutants from the air leading to improvement in air quality
S. This was the third time this year that the quality of air was registered as good
T. The Air Quality Index (AQI) on Tuesday was recorded at 38, which is the lowest this year, according to SAFAR
An AQI in the range of 0-50 is considered ‘good’, 51-100 ‘satisfactory’, 101-200 ‘moderate’, 201-300 ‘poor’, 301-400 ‘very poor’ and 401-500 ‘severe’
The passage is about improvement in Delhi's air quality. So sentence Q should be the opening sentence. It is because had there been no record of the air quality, we wouldn't be discussing this matter in the first place. The next sentence is S, as it shows the importance of the matter at hand. This shows that it is only the third time in a year that Delhi's air quality has been found to be good. The third sentence is T as it is giving us the exact figures related to the air quality. The fourth sentence is P giving us the remarks given by the Union Environment Minister and lastly, the fifth sentence is R.
Thus, the correct chronological order is QSTPR.
