In India, the first Public Accounts Committee was constituted in April 1950. According to P.D.T. Achary, former Secretary General of the Lok Sabha, “The practice of regularly referring bills to committees began in 1989 after government departments started forming their own standing committees. Prior to that, select committees or joint committees of the houses were only set up to scrutinise in detail some very important bills, but this was few and far between.”
Stat1: Parliamentary committees draw their authority from Article 105 (on privileges of Parliament members) and Article 118 (on Parliament’s authority to make rules for regulating its procedure and conduct of business).
Stat3: Committee reports are usually exhaustive and provide authentic information on matters related to governance. Bills that are referred to committees are returned to the House with significant value addition. However, Parliament is not bound by the recommendations of committees.

8. Consider the following statements regarding Dengue:
- Hot weather and intermittent rainfall favour the sustenance of Aedes aegypti —the vector transmitting the dengue virus.
- Dengue is mostly an asymptomatic infection, and only a very few develop severe disease.
- WHO highly recommends usage of complementary medicines like Nilavembu kudineer (a Siddha medicine) and papaya leaf extract for treating Dengue.
Which of the above statements is/are correct?
(a) 1 and 3
(b) 1 only
(c) 2 and 3
(d) 1 and 2
Dengue is essentially a tropical disease that occurs in the countries around the Equator; hot weather and intermittent rainfall favour the sustenance of Aedes aegypti —the vector transmitting the dengue virus —and Aedes albopictus, a minor contributor. Aedes eggs can remain dormant for more than a year and will hatch once they come in contact with water. Urbanisation, poor town planning, and improper sanitation are the major risk factors for the multiplication of such mosquitoes. Aedes mosquitoes cannot fly beyond a hundred metres. Hence, keeping the ambience clean can help prevent their breeding. Further, these mosquitoes bite during the daytime, so keeping the windows shut in the day hours is also useful.
Dengue is mostly an asymptomatic infection, and only a very few develop severe disease. Those very young or very old and those who have a chronic ailment are at a greater risk of developing severe disease. But the worldwide case fatality rate is as low as 0.3%.
Despite the adequate and well-formed guidelines for the management of dengue cases by the WHO and the Indian government, the usage of complementary medicines like Nilavembu kudineer (a Siddha medicine) and papaya leaf extract are rampant among the people. Nilavembu sooranam, which reportedly contains about nine different substances, has been widely promoted for use to treat dengue fever despite the safety of and complex interactions among its different constituents not having been tested.
There are case reports where Andrographis paniculata, an active constituent of Nilavembu sooranam, showed anti-fertility effects in animal models, causing abortion. Even meta-analysis of various studies has shown that there is no credible evidence for the use of papaya extract in dengue fever.
9. Consider the following statements regarding the “One Planet One City Challenge”
- It’s a friendly competition, organized by World Wide Fund for Nature (WWF) to mobilize cities to deliver on the Paris Agreement.
- The logo of WWF is a Red Panda.
- Pune was selected as a National Winner in 2017-2018 edition of WWF’s “One Planet City Challenge (OPCC)”.
Which of the above statements is /are correct?
(a) 1 only
(b) 1 and 2
(c) 3 only
(d) 2 and 3
The black-and white panda (a Giant Panda) is the logo of World Wide Fund for Nature. Panaji, Pune, and Rajkot were the three Indian cities which were selected as national finalists in 2017-2018 edition of WWF’s One Planet City Challenge (OPCC).
However, Rajkot emerged as the National Winner in 2017-2018 edition of WWF’s One Planet City Challenge (OPCC)
10. Consider the following statements:
- India has successfully achieved the complete phase out of Hydro chlorofluorocarbon (HCFC)-141 b, which is a chemical used by foam manufacturing enterprises.
- Before the phase out of Hydro chlorofluorocarbon (HCFC)-141 b, India was one of the major producers of HCFC-141b.
- The complete phase out of HCFC 141 b from the country is as agreed under Basel Convention.
Which of the above statements is/are correct?
(a) 1 and 2
(b) 1 and 3
(c) 2 and 3
(d) 1, 2 and 3
India has successfully achieved the complete phase out of Hydro chlorofluorocarbon (HCFC)-141 b, which is a chemical used by foam manufacturing enterprises and one of the most potent ozone depleting chemical after Chlorofluorocarbons (CFCs).
(HCFC)-141 b is used mainly as a blowing agent in the production of rigid polyurethane (PU) foams.
HCFC-141b is not produced in the country and all the domestic requirements are met through imports. With this notification, prohibiting the import of HCFC-141 b, the country has completely phased out the important ozone depleting chemical.
Simultaneously, the use of HCFC-141 b by foam manufacturing industry has also been closed as on 1st January, 2020 under the Ozone Depleting Substances (Regulation and Control) Amendment Rules, 2014. Nearly, 50 % of the consumption of ozone depleting chemicals in the country was attributable to HCFC-141 b in the foam sector.
The complete phase out of HCFC 141 b from the country in foam sector is among the first at this scale in Article 5 parties (developing countries) under the Montreal Protocol.
