Answer:
D) It is not really possible to tell if video game playing improves school grades.
Step-by-step explanation:
In this example, a logical fallacy that is contained in the researcher's statement is the assumption that playing video games improves school grades. However, he provides no evidence that leads to us to accept this justification. He tells us that it is difficult to find kids who earn poor grades but do well in video games. However, one is not necessarily the cause of the other one. For example, it is possible that children who play video games are wealthier than those who do not. This might mean that they also benefit from tutors or from cultural experiences that allow them to get better grades in school.
