Pre-thinking:The stimulus argues that it is not necessarily violent video games that cause children to be violent - it is possible that children who are already more likely to resort to violence are attracted to these violent video games.
Additionally, we can observe that the first bold face (BF1) is against the argument of the stimulus, and the second bold face (BF2) is supportive of the argument being made by the stimulus. Therefore, BF1 and BF2 are opposed to each other.
With the above in mind, let us examine what each option says about BF1:
A. The first provides an explanation that supports the position taken by the argument;
This is incorrect, the first opposes the argument. Eliminate.B. The first is a conclusion that is accepted by the argument as valid;
This is incorrect, the first opposes the argument. Eliminate.C. The first provides an explanation for an observed fact;
This is correct. Retain this option for now.D. The first states the position that the argument opposes;
This is correct. Retain this option for now.E. The first is a fact whose validity is questioned by the author;
This is incorrect. BF1 is not a fact but only an opinion/theory as evidenced by the prefix "Some researchers argue that...". EliminateLet us examine what each
remaining option says about BF2:
C. the second creates doubts about the applicability of the explanation to the observed fact.
This is correct and hence the correct answer option.D. the second states the conclusion of the argument.
This is not correct. BF2 only supports the argument and is not the conclusion. Eliminate.Hope this helps.
