Question

a prominent neurologist argues that an infant’s temperament (e.g., highly sensitive, easygoing) is almost entirely determined by the specific combinations of inherited neurotransmitters and hormonal balances present at birth, regardless of parenting style. this argument primarily supports which concept in the core developmental debates?
nurture
nature
stage
continuous
imagine a graph tracking a child’s height over time, showing a smooth, steady upward slope with no sudden jumps or sharp corners. this graph visually represents the core concept of which developmental theory regarding the rate of change?
discontinuous theory
continuous theory

Explanation:

First Question

The argument states that an infant's temperament is determined by inherited neurotransmitters and hormonal balances (nature - genetic/inherited factors) rather than parenting style (nurture - environmental factors). "Stage" relates to developmental stages, and "Continuous" to development type, which are not relevant here. So the concept supported is Nature.

A smooth, steady upward slope with no sudden jumps represents continuous change (gradual, unbroken development). Discontinuous theory involves distinct stages/jumps, so this graph represents Continuous theory.

Answer:

B. Nature
