H D3 TS Q11 – Selective High School

A study of kindergarten students found that children from households with many books (around 40–50) tend to have high reading achievement, while children from households with fewer books (around 10–20) tend to have lower reading achievement. Therefore, having greater access to books at home improves a child’s reading ability.

Which of the following, if true, would most strengthen this claim?

Many of the books in the homes of high-achieving readers were advanced textbooks kept out of the children’s reach.

Parents who buy more books for their children report feeling more satisfied as parents.
