At the age of four months, Zach was excitable and fearful. His dad taped a colorful picture beside the changing table to entertain Zach during diaper changes. Zach overreacted to the picture and became agitated and nervous. During his school years, Zach is most likely to:

A. become an extroverted member of his peer group
B. become fearful at the prospect of sleeping in an unfamiliar house
C. become curious about new school events
D. become angry and aggressive towards unfamiliar peers

If the picture did not involve persons, I would tend to pick B. The agitation is more likely to generalize to locations rather than persons.

Based on the information provided, Zach's initial response to the colorful picture suggests that he may have a tendency to become easily overstimulated and anxious. Therefore, option B is the most likely outcome for Zach during his school years. He is likely to feel fearful or anxious when faced with new or unfamiliar situations such as sleeping in an unfamiliar house.

To answer this question, we need to analyze the information given about Zach's behavior as a four-month-old and consider how it might influence his behavior during his school years.

At four months old, Zach was described as excitable and fearful. He overreacted to a colorful picture and became agitated and nervous. These early traits may indicate a tendency toward being more anxious or easily overwhelmed by certain stimuli.

Based on this information, option B, which suggests that Zach would become fearful at the prospect of sleeping in an unfamiliar house, seems to be the most likely choice. This option aligns with Zach's initial fearful reaction to a colorful picture, and suggests that he may have difficulty adapting to new or unfamiliar situations, such as sleeping in an unfamiliar house.

Option A, which suggests that Zach would become an extroverted member of his peer group, may be less likely because his initial behavior was described as excitable and fearful, which does not necessarily indicate a natural inclination toward extroversion.

Option C, which suggests that Zach would become curious about new school events, is also a possibility, but it does not directly address his initial fearfulness.

Option D, which suggests that Zach would become angry and aggressive towards unfamiliar peers, seems less likely because his initial behavior was described as fearful, not aggressive.

Therefore, option B, becoming fearful at the prospect of sleeping in an unfamiliar house, appears to be the most reasonable and supported choice based on the information provided.
