What may a rocket's payload contain aside from equipment?

1. Animals

2. Food supplies

3. People

4. Scientific instruments

The correct answer is: People

A rocket's payload can indeed contain people, which is a critical aspect of human spaceflight missions. When a rocket is launched with the intention of carrying astronauts into space, it must be designed and equipped to safely accommodate human passengers. This includes considerations for life support systems, such as oxygen supply, temperature control, and protection from radiation, as well as the need for safe re-entry and landing mechanisms to bring the crew back to Earth. While the other options also represent potential payloads—animals may be sent for research purposes, food supplies are essential for long-duration missions, and scientific instruments are vital for conducting experiments—human spaceflight specifically highlights the capability of rockets to transport people. This distinguishes human-centered missions from purely robotic missions, emphasizing the complex challenges and technologies involved in ensuring the safety and success of carrying astronauts into space.
