Question 1
Paper Ref: 0610/22_Spring_2026_Q38

Deforestation can have a negative impact on the environment.
Which statement about the negative impact of deforestation is correct?
0 O WW
It decreases the levels of carbon dioxide, which can lead to reduced rates of photosynthesis.
It decreases the amount of water flowing in local rivers, so there is less flooding.
It leads to soil loss, so there is less fertile soil for the growth of crops in the area.
It provides less land for the extraction of natural resources.

Options:
A
B
C
D
Correct Key: C

Question 2
