What phenomenon in adolescence suggests social relationships can affect biological functioning?

• A. The time her female roommate menstruates
• B. Her most stressful days of the month
• C. The days she feels most sexually aroused
• D. Her biological sister living in a different city

Answer: (A)

Social relationships can influence biological functioning, as shown by the idea that menstrual cycles can synchronize among women who share close living spaces. When a female roommate’s cycle is present in the same environment, social cues, shared routines, or pheromonal signals are thought to contribute to alignment of cycle timing over time. This illustrates how interpersonal context can modulate physiological processes, such as reproductive hormones. The other options don’t illustrate a social relationship influencing biology in the same direct way: stress levels tied to the month aren’t specifically about a social relationship; arousal is a physiological state not tied to the roommate dynamic; and a sister living in another city represents social relation but not the same short-term, shared-environment influence on biological timing.
