1. Question
With reference to rare earths minerals, consider the following statements:
1. The rare earths minerals (REM) are a set of seventeen metallic elements.
2. The REMs have unique catalytic, metallurgical, nuclear, electrical, magnetic and luminescent properties.Which of the statements given above are correct?
CorrectAnswer: C
What are REMs?
• The rare earths minerals (REM) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table in addition to scandium and yttrium that show similar physical and chemical properties to the lanthanides.
• The REMs have unique catalytic, metallurgical, nuclear, electrical, magnetic and luminescent properties. While named ‘rare earth’, they are in fact not that rare and are relatively abundant in the Earth’s crust.Strategic importance of REMs:
• They have distinctive electrical, metallurgical, catalytic, nuclear, magnetic and luminescent properties.
• Its usage range from daily use (e.g., lighter flints, glass polishing mediums, car alternators) to high-end technology (lasers, magnets, batteries, fibre-optic telecommunication cables).
• Even futuristic technologies need these REMs (For example high-temperature superconductivity, safe storage and transport of hydrogen for a post-hydrocarbon economy, environmental global warming and energy efficiency issues).
• Due to their unique magnetic, luminescent, and electrochemical properties, they help in technologies perform with reduced weight, reduced emissions, and energy consumption; therefore give them greater efficiency, performance, miniaturization, speed, durability, and thermal stability.IncorrectAnswer: C

2. Question
Which of the following statements is true about traditional CAR-T therapy?
CorrectAnswer: D. All of the above.
In traditional CAR-T therapy, an individual’s own T-cells are removed, modified to attack cancer cells, and then reintroduced into the body. However, when an individual is sick, it may not be possible to obtain enough healthy T-cells to create CAR-T cells. Donors can provide healthy T-cells, but these T-cells from a foreign body may attack the individual’s healthy cells, making the treatment counterproductive.IncorrectAnswer: D. All of the above.

3. Question
Which of the following statements regarding GI Tag are correct?
1. The GI Tags in India are governed by Geographical Indications (Registration and Protection Act), 1999.
2. The registration of a geographical indication is valid for a period of 15 years, previously it was 10 years now increased by 5 years.
3. GI is also governed by the World Trade Organization’s (WTO’s) Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), which India is Signatory
Select the correct answer using the code given below.CorrectAns;- c) Only 1 and 3
Explanation;-
The 2nd statement is incorrect because still the GI Tag validation is for 10 Years only not 15 Yrs.IncorrectAns;- c) Only 1 and 3
Explanation;-
The 2nd statement is incorrect because still the GI Tag validation is for 10 Years only not 15 Yrs. - Question 4 of 5
4. Question
Consider the following statements regarding Earth Observation Satellite (EOS-06)
1. It was launched by PSLV C54 launch vehicle.
2. It is designed to monitor ocean colour information, sea surface temperature information, and wind vector information for use in oceanographic, climatic, and meteorological applications.Which of the statements given above are correct?
CorrectAnswer: C
EOS-6:
• The Oceansat series’ third-generation satellite, the Earth Observation Satellite-06 (EOS-06), is designed to monitor ocean colour information, sea surface temperature information, and wind vector information for use in oceanographic, climatic, and meteorological applications.
• Chlorophyll, Sea Surface Temperature (SST), wind speed, and land-based geophysical characteristics are used by the satellite to identify possible fishing zones.IncorrectAnswer: C
