Read the passage and answer the question.
Many parents worry that video games harm their children's school work. A two-year study of 2,000 pupils, however, suggests a more complicated picture. The finding that pupils who played for less than an hour a day did slightly better in maths than those who never played, which surprised the researchers, does not mean that more gaming is better. Pupils who played more than three hours a day had the lowest scores of all the groups.
Which of the following best expresses the meaning of the sentence beginning with "The finding that"?
