Please answer the following question: Rob is experimenting with how air pressure works. To that end, he has designed two tests. In the first test the air flow works as it would in an airplane wing. He labels it as case A. In the second test the air flow works as it would in a race car spoiler. He labels it as case B. He is surprised to see that air flow behaves differently in different situations. Given the paragraph above, please answer correctly the following question: Would case B have faster or slower air flow above it than case A?
A:
slower
