Passage-1
An air quality index (AQI) is a way to combine measurements of multiple air pollutants into a single number or rating. This index is ideally kept constantly updated and available in different places. The AQI is most useful when lots of pollution data are being gathered and when pollution levels are normally, but not always, low. In such cases, if pollution levels spike for a few days, the public can quickly take preventive action (like staying indoors) in response to an air quality warning. Unfortunately, that is not urban India. Pollution levels in many large Indian cities are so high that they remain well above any health or regulatory standard for large part of the year. If our index stays in the Red/Dangerous' region day after day, there is not much any one can do, other than getting used to ignoring it.
Which among the following is the most logical and rational inference that can be made from the above passage?
- Our governments are not responsible enough to keep our cities pollution free.
- There is absolutely no need for air quality indices in our country.
- Air quality index is not helpful to the residents of many of our large cities.
- In every city, public awareness about pollution problems should increase.
