Answer:
The correct answer is option b. "lower than".
Step-by-step explanation:
The Home Observation for Measurement of the Environment (HOME) score measure the factors that affect children's development at home. The few studies that associate HOME scores with children's IQ scores have found that the associations for children who are adopted are lower than the associations found with children living with their biological parents. This suggest that children that had being with their parents since they birth, depend more on HOME scores to develop scores of intelligence.
