A Your experience was different than the research, so you should consult an expert and base your conclusions on what the expert says.
B Your experience could be an exception, while the research findings about the correlation between studying grades explain a high proportion of the many possible cases.
C Your experience was different than the research, so you should conclude that there is no relationship between study time and exam scores.
D You should ignore the research and base your conclusions on your own experience.
