<u>Marginal Costs & Marginal benefits in a choice you made.</u>
Assume that I want to buy an ornament for hands. I spend $500 for purchasing an ornament. When I was supposed to see another I wish to buy that. But spending again for the ornaments also not a good idea. I am also not willing in spending $500 for the ornament. So, I decided to go for an ornament that costed only $250. No, my marginal benefit get decreased from $500 to $250. When I decided to go fro the second one or more than one of same good my marginal benefits decrease.
Marginal cost is something that changes in a smaller range in the production of one additional unit. For example I decide to manufacture 500 pens. i need raw materials for the production and a building and machine for production. The change in the cost or expenses that happens when I decide to produce 600 pens is the marginal cost.

Explanation:
Robert graduate research project didn't state that all psychology students and classes are the sample he wants to use for his research. He only targets the Psychology students as his participants not sample. So the intuition from the question eliminates options B and C and the conclusion that can be drawn from the question above is that all the students in the psychology classes represent a portion of the sample Roberts wants to use to carry out his research just that he randomly chose some to be his participant.
