  • Thus statement 1 is correct.
  • Under the initiative, municipalities of any size can apply to be recognised as 'Tree City of the World', provided the urban community meets five core standard requirements.
  • Hence statement 2 is also correct.
  • Mumbai and Hyderabad were awarded the tag of '2021 Tree City of the World'.
  • The UN-FAO tag was awarded to Hyderabad (not Mumbai) for the second consecutive year and Mumbai (not Hyderabad) received it for the first time.
  • Thus statement 3 is NOT correct.

Q3. Consider the following statements:

1. Wheat is a kharif crop grown between September and December.
2. The best wheat is produced in areas favoured with cool, moist weather.
3. Areas with a warm and damp climate are not suited for wheat growing.

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

a) 1 only
b) 1 and 2 only
c) 2 and 3 only
d) All of the above

Answer: (C)

Explanation:

  • Wheat is a Rabi Crop grown between September and December and harvested between February and May. Hence, statement 1 is incorrect.
  • The best wheat is produced in areas favoured with cool, moist weather during the major portion of the growing period followed by dry, warm weather to enable the grain to ripen properly. Hence, statement 2 is correct.
  • Rains just after sowing hamper germination and encourage seedling blight. Areas with a warm and damp climate are not suited for wheat growing. Hence, statement 3 is correct.
