Question 1 of 5
1. Question
1 pointsConsider the following statements:
1. Arsenic is highly toxic in its inorganic form.
2. Arsenic in groundwater is caused by natural geologic processes.
3. Contaminated water used for drinking, food preparation and irrigation of food crops poses the greatest threat to public health from arsenic.Which of the given statements is/are correct?
Correct
https://newatlas.com/arsenic-breathing-microbes-ocean/59549/
Arsenic in groundwater is a geogenic contaminant i.e. caused by natural geologic processes.
Incidence of high arsenic in groundwater reported from various parts of the country, particularly in the Ganga- plains is a serious threat to the health of human being.
Arsenic occurrences in ground water in these areas is highly sporadic in nature and all the Arsenic is naturally present at high levels in the groundwater of a number of countries.
Arsenic is highly toxic in its inorganic form.
Contaminated water used for drinking, food preparation and irrigation of food crops poses the greatest threat to public health from arsenic.
Long-term exposure to arsenic from drinking-water and food can cause cancer and skin lesions. It has also been associated with cardiovascular disease and diabetes.
In utero and early childhood exposure has been linked to negative impacts on cognitive development and increased deaths in young adults.Incorrect

1. The Chief Election Commissioner and Election Commissioners are appointed by the Prime Minister to a tenure of six years, or up to the age of 65 years, whichever is earlier.
2. All business of the Election Commission shall only be transacted unanimously.Which of the given statement(s) is/are “incorrect“?
Correct
https://indianexpress.com/article/explained/dissent-election-commission-rules-pm-modi-lok-sabha-elections-5711378/
Section 10 (Disposal of business by Election Commission) of The Election Commission (Conditions of Service of Election Commissioners and Transaction of Business) Act, 1991, lays down that “all business of the Election Commission shall, as far as possible, be transacted unanimously”.
Dissent is, however, provided for in the Act itself, which says: “If the Chief Election Commissioner (CEC) and other Election Commissioners (ECs) differ in opinion on any matter, such matter shall be decided according to the opinion of the majority”.The CEC and ECs are appointed by the President to a tenure of six years, or up to the age of 65 years, whichever is earlier.
They enjoy the same status and receive salary and perks as judges of the Supreme Court of India.
The Election Commission of India draws its authority from the Constitution itself. Under Article 324, the powers of “superintendence, direction and control of elections” is to be vested in an Election Commission.Incorrect

Question 3 of 5
3. Question
1 pointsConsider the following statements regarding Pacific Decadal Oscillation (PDO):
1. PDO is a long-lived El Niño-like pattern of Pacific climate variability.
2. The PDO is detected as warm or cool surface waters in the Pacific Ocean, south of 20°S.
3. Both PDO and ENSO have similar spatial climate fingerprints yet the major difference is that PDO persists for 20-30 years while the typical ENSO persists for 6 to 18 months.Which of the given statement(s) is/are correct?
Correct
https://www.thehindu.com/sci-tech/science/why-is-northeast-india-drying-up-rapidly/article27033907.ece
The “Pacific Decadal Oscillation” (PDO) is a long-lived El Niño-like pattern of Pacific climate variability.
The PDO is detected as warm or cool surface waters in the Pacific Ocean, north of 20°N.
Major changes in northeast Pacific marine ecosystems have been correlated with phase changes in the PDO; warm eras have seen enhanced coastal ocean biological productivity in Alaska and inhibited productivity off the west coast of the contiguous United States, while cold PDO eras have seen the opposite north-south pattern of marine ecosystem productivity.Both PDO and ENSO have similar spatial climate fingerprints yet the major difference is that PDO persists for 20-30 years while the typical ENSO persists for 6 to 18 months.
The primary climatic fingerprints of the PDO are most visible in the North Pacific/North American sector, while secondary signatures exist in the tropics.
On the contrary, the primary climatic fingerprints of the ENSO are visible in tropics while secondary are visible in North Pacific/North American sector.The PDO has two cycles, viz. Cold Cycle and Warm Cycle, very much similar to La Nina and El Nino of the ENSO cycle.

Question 4 of 5
4. Question
1 pointsConsider the following statements regarding Global Assessment Report on Biodiversity and Ecosystem Services, which was in news recently:
1. This year’s publication marked the 10th anniversary of the report.
2. The report was released by Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).Which of the given statement(s) is/are correct?
Correct
https://indianexpress.com/article/explained/simply-put-why-biodiversity-report-matters-5715922/
The first-ever Global Assessment Report on Biodiversity and Ecosystem Services by Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) has been released.
The Global Assessment Report on Biodiversity and Ecosystem Services is termed as the first-ever such comprehensive report.
It took three years for a group of 145 expert authors from 50 countries to prepare this report based on more than 15,000 scientific and government documents.
It primarily looked or analysed the impact of economic development on nature and ecosystems.
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is an independent intergovernmental body, established by member States in 2012.
The objective of IPBES is to strengthen the science-policy interface for biodiversity and ecosystem services for the conservation and sustainable use of biodiversity, long-term human well-being and sustainable development.Incorrect

Question 5 of 5
5. Question
1 pointsFruits stored in cold chamber exhibit long storage life because ___:
Correct
UPSC 2013 Prelims Question
Respiration is the chemical process by which fruits and vegetables convert sugars and oxygen into carbon dioxide, water, and heat.
Metabolic activity in fresh fruits and vegetables continues for a short period after harvest. The energy required to sustain this activity comes from the respiration process. Respiration involves the oxidation of sugars to produce carbon dioxide , water and heat.
The storage life of a commodity is influenced by its respiratory activity. By storing a commodity at low temperature, respiration is reduced and senescence is delayed, thus extending storage life.Incorrect
