Oftentimes, our physical environment is
a. an extension of our personality
b. unrelated to what and how we communicate
c. determined by factors outside our control
d. difficult to describe

I find that the best answer is the following one:

c. determined by factors outside our control

For example, even though life is very hard in the very hot and the very cold regions, we can't control it: so this is an example of a physical environment that is hard to control.

In comparison, it is often easier to describe than our social environment.

Ithink it’s true as the answer.
