Question 5

The suffix “-graph” (from Greek “graphos”) refers to an instrument used to record (e.g., electrocardiograph, seismograph). “Formation” is not its meaning, “to separate” is incorrect, and “abnormal reduction in number” is unrelated.

The Framingham Heart Study, conducted in Framingham, Massachusetts, is the most important longitudinal heart study, focusing on cardiovascular disease risk factors over decades. The other cities do not host this key study.

Answer:

instrument used to record
