Question

select the best evidence to support the statement that older people with eye problems tend to have more medical problems.
among people aged 65 and older, over 40 percent of those who have vision problems say their overall health is only fair or poor, compared to just over 20 percent of those without vision problems. other health problems may include poor hearing, heart problems, and lower back pain.
older people often have more problems with their eyes, but children in preschool may not see as well as they should. just one out of seven preschoolers receives an eye screening, and fewer than one out of four receives some type of vision screening. the u.s. preventive services task force recommends vision screening for all children ages 3 to 5 years to find conditions such as amblyopia, which can be treated effectively if caught early.

Explanation:

The statement is about older people with eye problems having more medical issues. The first paragraph provides data (40% with vision problems have fair/poor health vs 20% without, plus other health issues) directly supporting this. The other paragraphs discuss children's vision screening, not older adults' medical problems related to eye issues. So the first paragraph is the best evidence.

Answer:

Among people aged 65 and older, over 40 percent of those who have vision problems say their overall health is only fair or poor, compared to just over 20 percent of those without vision problems. Other health problems may include poor hearing, heart problems, and lower back pain.
