Mark conducts a study for his research methods class to determine if consuming caffeine causes people to perform better on cognitive tasks.In his study,he gives half of his participants a glass of water and half of his participants a glass of cola,and then has them attempt to solve 15 math problems.He finds that people who drink caffeine beforehand solve more math problems than those who drink water beforehand.

-Mark decides to conduct a conceptual replication.Which of the following could be in the study to make it this type of replication?
A)Measuring a different group of participants
B)Having participants drink a caffeinated energy drink rather than a caffeinated cola
C)Measuring the same participants one week later
D)Having participants complete 10 math problems instead of 15

Conducting a conceptual replication involves changing the method or context of the original study while keeping the concept or hypothesis the same. Switching to a caffeinated energy drink instead of a caffeinated cola is a change in method while keeping the concept the same. Therefore, option B is the best choice. Measuring a different group of participants (A) or having participants complete fewer math problems (D) do not necessarily change the method or context of the original study, while measuring the same participants one week later (C) is a replication of the same study rather than a conceptual replication.
