    3. Consider the following statements regarding the Air Quality Index (AQI):
    I. AQI is calculated based on both particle and gaseous pollutants in the air, including PM10 and PM2.5 (particles with diameter less than 10 and 2.5 micro metres), NO2, SO2, NH3, lead, CO and O3.
    II. PMs are the pollutants responsible for respiratory and cardiovascular diseases, while Nitrogen Dioxide (NO2) and others cause lung diseases, lung tissue damage, reduction of lung function and eye-related issues.

    Which of the following statement(s) is/are correct?
    a. Only I
    b. Only II
    c. Both I and II
    d. Neither I nor II

    Answer: c

    Explanation:

    An air quality index is a number used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become. As the AQI increases, an increasingly large percentage of the population is likely to experience increasingly severe adverse health effects.

    PMs are the pollutants responsible for respiratory and cardiovascular diseases, while Nitrogen Dioxide (NO2) and others cause lung diseases, lung tissue damage, reduction of lung function and eye-related issues.

    4. Recently, India has established a Joint Committee under the Scientific and Technological Cooperation Agreement re-launch of cooperation in the sectors of science, technology and innovation in which of the following countries?
    a. Russia
    b. USA
    c. Italy
    d. Australia

    Answer: c

    Explanation:

    Recently, India has established a Joint Committee established under the Scientific and Technological Cooperation Agreement re-launch of cooperation in the sectors of science, technology and innovation. The original agreement was signed between Italy and India in 2003.
