Correct Answer: D

Rationale: Preterm newborns, like Cheryl, experience a higher percentage of REM sleep compared to full-term newborns. This is because REM sleep plays a critical role in brain development, and preterm infants have an increased need for brain development due to their early arrival. Therefore, Cheryl, as a preterm newborn, is most likely to experience the greatest percentage of REM sleep among the individuals listed.

Rationale: The correct answer is D because the statement aligns with the concept of reciprocal influences in human development. The new evidence suggests that individuals are not only influenced by the contexts in which they develop but also contribute to shaping those contexts. This idea highlights the dynamic and interactive nature of human development, emphasizing the bidirectional relationship between individuals and their environments.

This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

Correct Answer: D

Rationale: Alfred Binet and Theodore Simon constructed the first successful intelligence test, known as the Binet-Simon scale, in an effort to measure a child's intelligence level. This test was groundbreaking at the time and laid the foundation for the development of future intelligence tests.
