Question 1 of 5
1. Question
1 pointsConsider the following statements regarding Black holes.
- A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape from it.
- The area outside the boundary of Black holes, called the event horizon does emit all kinds of radiations, even visible light.
Which of the above statements is/are incorrect?
Correct
Solution: d)
Black holes do not emit or radiate anything, even light. So, there is no way their image can be captured. But the area just outside its boundary, called the event horizon, which has vast amounts of gas, clouds and plasma swirling violently, does emit all kinds of radiations, even visible light.

Question 2 of 5
2. Question
1 pointsConsider the following statements regarding CRISPR–Cas9.
- CRISPR technology allows to easily alter DNA sequences and modify gene function.
- It can be used to correct sickle cell anemia, a genetic blood disorder.
- Gene editing system does not occur naturally in organisms.
Which of the above statements is/are correct?
Correct
Solution: a)
Indian scientists have developed a new variant of currently popular gene editing tool, CRISPR-Cas9, and have shown that this variant can increase precision in editing genome while avoiding unintended changes in DNA.
The researchers have also shown that this type of gene editing can be used to correct sickle cell anemia, a genetic blood disorder.
By reprogramming and using a naturally occurring gene editing system – CRISPR-Cas9 – found in bacteria, scientists globally have been engaged in ‘editing’ genome of various organisms.
CRISPR-Cas9 stands for ‘Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9.’ This protein can be programmed to go to a desired location in the genome and correct or edit defective strands (such as those involved in certain diseases) of DNA. The technology, when perfected, may be used to treat several genetic disorders.

Question 3 of 5
3. Question
1 pointsConsider the following statements regarding Natural Gas.
- Natural gas consists primarily of Nitrogen but also includes small percentage of carbon dioxide and methane.
- Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds.
- It is used as a chemical feedstock in the manufacture of plastics and organic chemicals.
Which of the above statements is/are correct?
Correct
Solution: c)
Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years.
Natural gas is a non-renewable hydrocarbon used as a source of energy for heating, cooking, and electricity generation. It is also used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals.
Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds and as methane clathrates.

Question 5 of 5
5. Question
1 pointsConsider the following statements regarding production of maize in India.
- India is one of the major Maize producing countries in the world and has been self-sufficient in its produce.
- In India, Maize is grown throughout the year, but is predominantly a kharif crop.
- Major Maize growing states in India are Karnataka, Telangana, Maharashtra and Andhra Pradesh.
Which of the above statements is/are correct?
Correct
Solution: d)
In India, Maize is grown throughout the year. It is predominantly a kharif crop with 85 per cent of the area under cultivation in the season. Maize is the third most important cereal crop in India after rice and wheat. It accounts for around 10 per cent of total food grain production in the country. In addition to staple food for human being and quality feed for animals, maize serves as a basic raw material as an ingredient to thousands of industrial products that includes starch, oil, protein, alcoholic beverages, food sweeteners, pharmaceutical, cosmetic, film, textile, gum, package and paper industries etc.
Major maize growing states in India are Karnataka, Madhya Pradesh, Bihar, Tamil Nadu, Telangana, Maharashtra and Andhra Pradesh.
India has allowed imports of 1 lakh tonne of maize during 2019-20 under tariff rate quota (TRQ) system.
