Question

while researching a topic, a student has taken the following notes:

• reasons to avoid impact related to surface.
• common running surfaces include grass, synthetic track, and concrete.
• a group of researchers wondered what the magnitude of impact on different surfaces was, so they recruited thirty student runners.
• runners used their own shoes on each of the surfaces, and peak impact was compared.
• concrete had the greatest peak impact, which suggests it might lead to more injuries than the other two surfaces.

the student wants to present the research study and its methodology. which choice most effectively uses relevant information from the notes to accomplish this goal?
select one answer.
a to help runners avoid injury on different surfaces, researchers studied the peak impact as people ran on concrete, grass, and artificial track.
b to identify the running surface that produces the greatest impact, researchers measured the peak impact as runners ran on concrete, grass, and artificial track.
c because they recruited runners wearing their own shoes, peak impact was measured on concrete, grass, and artificial track.
d because peak impact is related to surface, researchers had runners run on concrete, grass, and an artificial track and then took measurements.

Explanation:

To present the research study and its methodology, we need to include the key elements: the research question (what was studied), the method (how data was collected), and the findings (comparison of peak impact). Option B states "To identify the running surface that produces the greatest impact, researchers measured the peak impact as runners ran on concrete, grass, and artificial track." This includes the research goal (identify surface with greatest impact), the method (measuring peak impact while running on different surfaces), and the surfaces tested, which effectively presents the study and its methodology. Option A focuses on helping runners avoid injury (not the study's methodology), Option C is about why they recruited runners (not the methodology), and Option D is about the measurement process but not the overall study and methodology.

Answer:

B. To identify the running surface that produces the greatest impact, researchers measured the peak impact as runners ran on concrete, grass, and artificial track.
