B.

What is a better predictor than the ethnicity of a child's intelligence and performance?

Correct Answer
SES

Explanation
SES, or socioeconomic status, is a better predictor than the ethnicity of a child's intelligence and performance. SES takes into account various factors such as income, education level, and occupation of the child's family, which have a significant impact on the child's opportunities and resources. It recognizes that children from different socioeconomic backgrounds may have different access to quality education, healthcare, and other resources that can influence their intelligence and performance. In contrast, ethnicity alone does not provide a comprehensive understanding of the child's socioeconomic circumstances and the potential disparities they may face.

A.

Affects crystallized intelligence
B.

Measures nonverbal reasoning
C.

Unlikely to be culturally biased
