Malia is 10 years of age, and her grandmother, Anna Rosa, is 60 years old. Which statement is likely to be true concerning their sleep patterns? A Anna Rosa is more likely than Malia to have night terrors. B Anna Rosa sleeps fewer hours per day than Malia does. C Anna Rosa spends more of her sleep time in deep sleep than Malia does. D Anna Rosa and Malia have the same sleep patterns.

The correct answer is:<br /><br />**(B) Anna Rosa sleeps fewer hours per day than Malia does.**<br /><br />### Explanation:<br />1. **Sleep duration by age:**<br /> - Children, like Malia (10 years old), typically require more sleep—around 9-11 hours per night.<br /> - Older adults, like Anna Rosa (60 years old), generally need less sleep—around 7-8 hours per night on average.<br /><br />2. **Night terrors:**<br /> - Night terrors are more common in children than in older adults, so **A** is incorrect.<br /><br />3. **Deep sleep:**<br /> - As people age, the amount of time spent in deep sleep (slow-wave sleep) decreases. Older adults like Anna Rosa spend less time in deep sleep compared to children like Malia. Therefore, **C** is incorrect.<br /><br />4. **Same sleep patterns:**<br /> - Sleep patterns change significantly with age, so it is unlikely that Anna Rosa and Malia have the same sleep patterns. Thus, **D** is incorrect.<br /><br />Hence, the most likely statement is **(B)**.
