With regard to farming, what do you think is the best use of chemicals and why?

The correct answer to this open question is the following.

Regarding farming, the best use of chemicals is a moderate one in order to not affect the crops. In big farming corporations, they use all kinds of pesticides to produce more crops because it's a business. But it is too much poison in fruits and vegetables that affects the nutrients of the food and could affect people when they consume these products. The farming industry is using pesticides, fungicides, insecticides, and more, to produce more food and trade it.

Natural pesticides are the best solution to cause less damage to plants and humans. More and more farmers are using organic pesticides although they are more expensive.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.

the answer is c i just put d and i got it wrong so yeah its d
