1. **Sleep Question Analysis**

- The statement "Men's sleep is interrupted, on average, as much as women as they take care of babies and small children" is not generally accurate because research shows that women often experience more sleep disruption due to childcare responsibilities.
   - The statement "African Americans have more sleep problems than European Americans" is supported by research indicating higher prevalence of issues such as short sleep duration and sleep disorders among African Americans.
   - The statement "European Americans tend to sleep better than Asian Americans" is less supported by research findings compared to the disparities noted between African Americans and European Americans.
   - The statement "Women report getting more sleep than men" contradicts many studies where women often report more sleep disruptions and sometimes even shorter sleep duration than men.

Thus, the true statement is:  
   $$
   \text{African Americans have more sleep problems than European Americans.}
   $$

2. **Drug Classes Question Analysis**

- Hallucinogens alter perception and are not generally classified as depressants.
   - Amphetamines are central nervous system stimulants.
   - Stimulants, by definition, increase activity in the nervous system.
   - Barbiturates are a class of drugs known as "downers" because they depress the central nervous system.

Therefore, the correct answer is:  
   $$
   \text{Barbiturates.}
   $$
The true statement about sleep is that African Americans have more sleep problems than European Americans. The correct drug class considered "downers" is Barbiturates.
