Context: People can use the engineering-design process to develop solutions to problems. One step in the process is testing if a potential solution meets the requirements of the design.
The passage below describes how the engineering-design process was used to test a solution to a problem. Read the passage. Then answer the question below.

Wind turbines use wind power to produce electricity. Miranda was a materials engineer who designed wind turbines. She wanted to design a new turbine that would produce 10% more electricity than older wind turbines. She thought that a turbine made from lightweight material would turn more easily and produce more electricity. So, Miranda created a computer model of a turbine made from lightweight material. Then she used the model to calculate how much more electricity the new turbine could produce compared to the older turbines.
Figure: studying a wind turbine computer model.
Which of the following could Miranda's test show?
A. how much the new turbine would weigh
B. if the new turbine could turn easily
C. whether the new turbine could produce 10% more electricity
Answer with the option's letter from the given choices directly.

C
