Hi!
Your answer is C.
A is an example because it's not good to only make identify one solution; you need backups or a variety of ways.
B is an example because, hey, not everything is true! Especially on the internet. Questioning source information is great because then you are sure what you are seeing is unbiased and accurate.
C is NOT an example. As stated above, you need a variety of solutions, but you can't just pick the first solution; you want to pick the <em>best</em> solution for the problem at hand.
D is an example. As stated above, questioning source information is great, but then you need to also verify it, because, like said before, not everything is true.
If you're on Edgeunity I pretty sure the answer is "The opportunity for advancement or promotion could result in higher pay"
I would say this comes from the sociological perspective of the ordinary patients who require medicine and general health care and who may not be able to afford it since for example medicines are so expensive that without medicare or a good private health plan they may be out of reach of people's income.
