Statement 2 – The more extreme the outside temperature, the lower the
number of DD and the lower the requirement of energy for space heating or
cooling.
Which one of the following is correct in respect of the above statements?
(a) Both Statement-I and Statement-II are correct and
Statement II is the correct explanation for Statement-I.
(b) Both Statement-I and Statement-II are correct and Statement II is not the

(c) Statement-I is correct but statement II is incorrect.
(d) Statement -I is incorrect but Statement -II is correct.
Answer: (C)
Explanation:
- Degree days are measures of how cold or warm a location is and is used to assess the energy needed to keep people comfortable. A DD compares the mean outdoor temperatures recorded for a location to a standard temperature. Hence, statement 1 is correct.
- The more extreme the outside temperature, the higher the number of DD and the higher the requirement of energy for space heating or cooling. A Cooling DD quantifies the energy requirement for cooling while a Heating DD quantifies the energy requirement for heating. Hence, statement 2 is incorrect.
2. Bedaquiline, recently seen in news is used to treat which of the following disease?
(a) Cancer
(b) Tuberculosis
(c) Malaria
(d) Hepatitis
Answer: (B)

E-cigarettes’ aerosols have harmful substances such as nicotine, cancer-causing chemicals, heavy metals such as nickel, tin and lead, chemicals causing lung diseases such as diacetyl. An electronic cigarette is a battery-operated device that emits a vaporized solution to inhale. These devices have various names, including e-cigarettes, e-hookahs, vaporizer cigarettes, vapes, and vape pens. Hence, statement 1 is correct.
- Ministry of Health and Family welfare launched an online portal for reporting of violations under Prohibition of Electronic Cigarettes (Production, Manufacture, Import, Export, Transport, Sale, Distribution, Storage and Advertisement) Act (PECA). All forms of Electronic Nicotine Delivery Systems including e-cigarettes are prohibited under PECA. Hence, statement 2 is correct.
4. Consider the following statements regarding Waterspout:

- Most often, tropical and subtropical regions are where waterspouts develop. But on rare occasions, regions like Antarctica, Australia, New Zealand, and the Middle East also record these. Hence, statement 2 is incorrect.
- Tornadoes that originate over water or migrate from land to water are referred to as tornadoes with waterspouts. They have many traits with a land tornado. They are linked to violent thunderstorms and frequently come with strong winds, rough seas, significant hail, and perilous lightning. Hence, statement 3 is correct.
