AI Explanation

To answer this question, let's analyze each option:

Option A) Only people who have the opportunity for formal schooling develop nearsightedness. This option is incorrect because the statement does not provide enough evidence to conclude that only people who have the opportunity for formal schooling develop nearsightedness. It only states that two-thirds of the children developed nearsightedness after starting school.

Option B) People who are illiterate do not suffer from nearsightedness. This option is incorrect because the statement does not provide evidence to support this conclusion. It only states that illiterate parents and grandparents showed no signs of nearsightedness, but it does not generalize this to all illiterate people.

Option C) The nearsightedness in the children is caused by the visual stress required by reading and other class work. This option is the correct answer because the statement supports this conclusion. It states that two-thirds of the children developed considerable levels of nearsightedness after starting school, which implies that the visual stress required by reading and other class work may have caused the nearsightedness.

Option D) Only literate people are nearsighted. This option is incorrect because the statement does not provide evidence to support this conclusion. It only compares the nearsightedness in children to their illiterate parents and grandparents, but it does not generalize this to all literate people.

Option E) One-third of the children are illiterate. This option is incorrect because the statement does not provide evidence to support this conclusion. It only states that two-thirds of the children developed nearsightedness, but it does not provide information about their literacy status.

Therefore, the correct answer is C) The nearsightedness in the children is caused by the visual stress required by reading and other class work.
