Question

select the correct answer. which action is the best example of muscular strength?
a. walking to school with a backpack
b. cooking dinner for your family
c. swimming across a lake
d. lifting a heavy box into a car

Explanation:

Muscular strength is the ability of a muscle to exert force against resistance. Lifting a heavy box into a car requires a muscle to exert a large amount of force to overcome the weight of the box, which is a classic example of using muscular strength. Walking with a backpack (A) and swimming across a lake (C) are more related to muscular endurance (sustained activity over time), and cooking dinner (B) involves more fine motor skills and less forceful muscle exertion against heavy resistance.

Answer:

D. lifting a heavy box into a car
