Question

multiple choice question
how many power sources does a car like this have?
a. 1
b. 2
c. 3
d. 4

Explanation:

Assuming this is a hybrid car (a common context for such questions), hybrid cars typically have two power sources: an internal combustion engine and an electric motor (with its associated battery as an energy storage, but the power - generating/propelling sources are the engine and the motor, so two main power sources for propulsion).

Answer:

B. 2
