Question #N381

A recent study found that people are more likely to remember information when they have a personal connection to it. In other words, the more meaningful the information is to someone, the more likely they are to recall it. For instance, people are more likely to remember the name of their first pet than they are to remember the names of all the U.S. presidents. This is because they have a personal connection to the names of their pets, but they do not have a personal connection to the names of all the U.S. presidents. This suggests that meaningfulness plays a role in memory.

Which of the following revisions to the underlined portion of the passage would be most effective in improving the clarity and conciseness of the passage?
A. —meaningfulness plays a role in memory.
B. , a factor that contributes to memory.
C. , which has an impact on memory.
D. , and that is an important factor in memory.
