Lindsay's IQ score is likely to be: a. higher then her sister's score b. the same as her sister's score c. lower then her sister's score d. one standard deviation lower than her sister's score

A. Higher than her sister's score

Explanation:

Social and economic stress leads a child to less IQ level than a privileged child. It's because they have low opportunities to learn and grow, they struggle from the childhood and may have little or no access to education. Meanwhile a child in privileged family doesn't face difficulties and they get education from much advanced institutes.
