Answer:c. A country with a low physiological density and low arithmetic density
Explanation:
The physiological density which is also known as real population density refers to how many people are found in an area that can be used to grow crops.
If the physiological density is high that means that there is less land available which can be used to grow crops which reduces the agricultural products in that area.
If more people occupy a space which can be used to plant then that takes away the ability of that land to produce agriculturally.
Arithmetic density refers to the number of people that are found in that land whether rural or urban or any other area.
If the number of people per area is high that means the place is congested and there is no area to plant any crops or do any other agricultural activities.
If all these values are low in a country that means available places that can be used for agricultural activities are plenty which gives the country an advantage to have more agricultural products that they can even export it .
In some research, the researchers are not able to use random assignments to divide participants among groups. Instead, they compare preexisting groups, which results in a quasi-experimental design.
Random assignments are those which are given as a matter of chance to ensure fairness and equal opportunity for all participants. Here participants forming multiple groups are with similar characteristics. So all groups are the same at the start of the experiment.
A quasi-experimental design applies a non-random method, and subjects are assigned to preexisting groups. There are some situations where true experiments can't be used for practical reasons. In such cases, a quasi-experimental design is a suitable tool.

One Effect is that it takes up a lot of fertile soil and that causes pollution. Hoped I helped. :)
