Which is not a major factor resulting in pollution from increased economic activity in China?

a. More people are driving motor vehicles.
b. More factories are burning coal.
c. More farmlands are being cleared.
d. More bicycles are being used for traveling purposes.***

Well, it looks like "d" is the odd one out here. While all the other options contribute to pollution in China, using more bicycles for traveling purposes doesn't really have a negative impact on the environment. In fact, it's quite the opposite! Riding bicycles is a great way to reduce pollution and get some exercise at the same time. So, go ahead and pedal away!

The correct answer is d. More bicycles are being used for traveling purposes.

To determine which option is not a major factor resulting in pollution from increased economic activity in China, let's analyze each option:

a. More people are driving motor vehicles: This could contribute to pollution due to increased emissions from vehicles.

b. More factories are burning coal: This could contribute to air pollution as coal burning emits harmful gases.

c. More farmlands are being cleared: This could contribute to pollution through deforestation and the loss of natural habitats.

d. More bicycles are being used for traveling purposes: This option, in contrast to the others, does not contribute to pollution. Bicycles do not emit harmful gases or pollutants, and they provide an environmentally friendly means of transportation.

Therefore, the answer is d. More bicycles are being used for traveling purposes, as this is not a major factor resulting in pollution from increased economic activity in China.

Correct.
