Final answer:
Evelyn and Phillip, due to their significant age gap, are likely to have different sleep patterns; with Evelyn possibly experiencing lighter sleep or less overall sleep, while Phillip requires more sleep to support his development.
Step-by-step explanation:
The question concerning Evelyn who is sixty years old and her one-year-old nephew Phillip relates to the differences in sleep patterns and needs across different ages. Generally, as people age, they may experience changes in sleep quality and require less sleep, while infants like Phillip typically need more sleep to support their rapid development. An older adult may experience lighter sleep or insomnia and might not need as much sleep as a younger person. In contrast, infants often sleep between 12-16 hours a day, spread throughout the day and night, as their bodies and brains are developing rapidly. Although individual sleep needs can vary widely regardless of age, these are typical patterns observed among older adults and infants.
