A study of kindergarten students has shown that children from households that own many books, an average of 54 books, show average or high reading achievement levels, while the households of children with lower reading achievement levels tend to own fewer books, 5 books on average.

What additional information would strengthen the assertion that parents who don`t buy children`s books to keep in the home cause their children to fall behind their peers in reading skills?


A. Many of the books in the homes of the high achieving readers from the study were advanced science textbooks that were stored out of reach of the children.

B. When children have books of their own, they develop more advanced reading skills because adults are more likely to read to them regularly.

C. The children in the study all had unlimited access to thousands of elementary school library books.

D. Children whose parents buy them books feel happier about their lives.

E. The non-school hours of every child in the study were entirely filled with sports activities, television watching, and playing with friends.

Logical gap :
Children from households that own many books show average or high reading achievement levels, while the households of children with lower reading achievement levels tend to own fewer books. But, what if the children from households that own many books have aversion to reading ?

B. When children have books of their own, they develop more advanced reading skills because adults are more likely to read to them regularly. --> Correct, fills the logical gap, and thus strengthens the claim

Hence, B.

The answer is B.
We can solve this question using the

Logical

approach, because this question is all about the logic of causation.
the argument cites a correlation between having books in the house and reading achievement, and claims this implies causation between the two. However, correlation does not necessitate causation on its own - we need a data point which will give us a reason that links having books in the house and reading achievement. B does exactly this: B. When children have books of their own, they develop more advanced reading skills because adults are more likely to read to them regularly.
