Question

why does girl on the bike stops peddling after about 30 seconds? (select all that apply)

she needs to replace the chemical energy she used up.

she got bored.

she needs food to provide her with chemical energy.

she needed to rest.

she ran out of energy.

Explanation:

Peddling uses chemical energy from the body. Running out of usable energy (a biological need) leads to stopping. Needing to replace used chemical energy and needing food (to replenish that energy) are linked biological reasons. Boredom is not a biological necessity, and "needed to rest" is vague compared to energy-related causes.

Answer:

She needs to replace the chemical energy she used up., She needs food to provide her with chemical energy., She ran out of energy.
