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 refers to the ability of a muscle or group of muscles to exert force against resistance. Lifting a heavy box into a car requires a significant amount of force to overcome the weight of the box, which is a direct demonstration of muscular strength. Walking to school with a backpack (A) and swimming across a lake (C) are more related to muscular endurance (the ability to sustain repeated contractions or activities over time). Cooking dinner (B) involves various tasks but not a primary demonstration of muscular strength.

Answer:

D. lifting a heavy box into a car
