A landscaping worker carries wood and loads it (5.5 METs). This activity represents:

• A. Light intensity
• B. Moderate intensity
• C. Low-moderate intensity
• D. Vigorous intensity

Answer: (B)

The key idea is using METs to categorize how hard an activity makes your body work. MET stands for metabolic equivalent, with 1 MET being the oxygen cost of resting. Activities are grouped by energy cost: light (<3 METs), moderate (3–6 METs), and vigorous (>6 METs). A task that involves carrying and loading wood at about 5.5 METs requires more effort than light activities and raises your heart rate and breathing to a noticeable, sustainable level without reaching maximal effort. Therefore, it fits the moderate-intensity category. The other options don’t match because light intensity would be under 3 METs, and vigorous would be above 6 METs; “low-moderate” isn’t a standard category here.
