How many researchers are described in the material?

• A. 3
• B. 4
• C. 5
• D. 6

Answer: (B)

Counting the number of researchers described in the material means identifying every person who performs research activities or is explicitly labeled as a researcher. Look for roles like principal investigator, co-investigator, research scientist, postdoctoral fellow, graduate student conducting experiments, or research assistant. Create a quick list of unique individuals who are described in those terms, and avoid double-counting anyone mentioned more than once. Exclude participants, administrators, or staff not involved in conducting or analyzing the research. If four distinct individuals are described in researcher roles, then the material describes four researchers.
