How many health benefits of exercise are listed?

• A. 6
• B. 7
• C. 9
• D. 8

Answer: (D)

The main idea being tested is accurately counting the distinct benefits listed for exercise. The correct choice is eight because the material presents eight separate benefits, each listed as its own item. To verify, go through the Benefits of Exercise section and count each clearly stated benefit once, making sure not to double-count or lump together items that the author treats as separate entries. If something looks like a single long sentence, check whether it’s describing one benefit or multiple ones; in this item, the eight distinct benefits are clearly separated, so the total count is eight. The other numbers would only fit if you miscounted or treated a combined item as multiple benefits, which isn’t how the list is structured.
