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. Shivani 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, Shivani 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 Shivani's test show?
A. if the new turbine could turn easily
B. whether the new turbine could produce 10% more electricity
C. how much the new turbine would weigh
From the given choices, pick the correct answer and respond by indicating the letter of the correct option.

B
