Answer:
the cost of a post secondary degree is worth it.
Explanation:
The correct answer is "the cost of a post secondary degree is worth it". This is because the statement implies that having this kind of degree is better than having a secondary degree.
Here are the reasons why the other answers are not correct:
- "the cost of a post secondary degree should be avoided": this is false, as the statement on the question says that in the long term it is better to have a post secondary degree.
- "you should not be concerned about the amount of debt you go into to pay for it": the statement provided discusses that it is better to have post secondary degree than not habing it. It does not address being concerned about its cost. It is always recommended to understand how you are going to pay for a degree, so you can plan for which kind of job you will need to have after finishing the degree as well as how much money you need to earn to have good quality of life.
- "the more money you pay for the degree guarantees a higher salary": the statement does not talk about the ratio between salary and cost of a degree.
