b) 2 and 3 only
c) 1 and 3 only
d) All of these

Answer: (B)

Explanation:

  • It is a first-of-its-kind, whole-of-government exercise to provide world-class infrastructure across India.
  • The NIP aims to capture key greenfield and brownfield projects for investments across all economic and social infrastructure sub-sectors on a best-effort basis.
  • It is a group of social and economic infrastructure projects

Q2. Consider the following statements:

1. New Delhi Municipal Corporation (NDMC) prepared the first Heat Action Plan in India.
2. Heatwave is India’s second most lethal disaster after the flood.

Which of the statement/s given above is/are correct?

c) Both 1 and 2
d) Neither of these

Answer: (B)

Explanation:

  • Ahmedabad Municipal Corporation (AMC) prepared the first Heat Action Plan in 2013.
  • Heatwave is India’s second most lethal disaster after the flood, so the government should declare it a natural disaster to prevent further losses

Q3. Consider the following statements about Industrial Revolution

Q4. Consider the following statements about lithium-ion batteries:

1. A lithium-ion battery or Li-ion battery is a type of rechargeable battery composed of cells in which lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge and back when charging.
2. Li-ion batteries have a low energy density, high memory effect and low self-discharge.
3. They can be a safety hazard since they contain flammable electrolytes and if damaged or incorrectly charged, they can lead to explosions and fires.

Choose the correct statements:

a) 1 and 2 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2 and 3

Answer: (C)

Explanation: Lithium-ion Battery

  • A lithium-ion battery or Li-ion battery is a type of rechargeable battery composed of cells in which lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge and back when charging.
  • Li-ion cells use an intercalated lithium compound as the material at the positive electrode and typically graphite at the negative electrode.
  • Li-ion batteries have a high energy density, no memory effect and low self-discharge. Thus, the second statement is incorrect.
  • Cells can be manufactured to prioritize either energy or power density.
  • They can however be a safety hazard since they contain flammable electrolytes and if damaged or incorrectly charged can lead to explosions and fires.

Q5. Consider the following statements:

1. India is the world’s largest producer of wheat in the world.
2. Indian wheat has a good capacity of heat tolerance.

Which of the above given statements is/ are correct?

a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither of these

Answer: (D)

Explanation:

  • India is the world’s second largest producer of wheat.
  • Indian wheat is at the limit of heat tolerance. In the critical growing months of January and February and till mid-March the mean day temperature has to be crop friendly at around 20-21 degrees Celsius. Any marked rise in day temperature would hurt the crop yield.
