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.

Mark was a mechanical engineer who was designing  to record temperature, precipitation, and wind speed. The weather station would be used in a town where the highest recorded temperature was 40°C. Mark wanted to make sure the weather station would work even in unusually warm weather.
So, he set an indoor test chamber to 50°C with low moisture and no wind. He left the weather station in the chamber overnight. The next day, he checked to see if the weather station displayed accurate measurements after 24 hours at 50°C.
Figure: a weather station.
Which of the following could Mark's test show?
A. how well the weather station would work when it was windy
B. if the weather station would work when the temperature was 50°C
From the given choices, select the correct answer and reply with the letter of the chosen option.

B
