Question

instructions read the question carefully and select the best answer. the counterpoint author most likely includes the following passage to — however, studies of adopted children show some similarity in iq both to their adoptive parents and to other children raised in the same household who are unrelated to them. in fact, a french study showed that transferring babies from impoverished households to wealthy ones improved childhood iq scores by 12 to 16 points. a suggest that children who are adopted do not have genetic similarities to the iq of their adoptive parents b say that poor people are often less intelligent than rich people c demonstrate that intelligence can be increased or decreased by a child’s home and family d prove that iq doesn’t mean anything because it can be affected by changes in environment

Explanation:

The passage notes adoptees share IQ similarities with unrelated adoptive parents, and that moving impoverished babies to wealthy households raised their IQ by 12-16 points. This shows environment/home context impacts IQ (intelligence) by changing scores. Option A is incorrect because the passage shows IQ similarity to adoptive parents, contradicting no genetic similarity claim. Option B is not addressed; the passage does not compare inherent intelligence of rich vs poor people. Option D is wrong because the passage does not argue IQ is meaningless, it shows it can be affected.

Answer:

C. demonstrate that intelligence can be increased or decreased by a child's home and family
