The Future of Space Travel May Not Lie with Humans

question 358

Multiple Choice

The future of space travel may not lie with humans, but with robots. At the dawn of the space age, space travel required human astronauts-they were simply more capable than robots. But humans developed technology that steadily made robots more attractive. Astronauts have to breathe, eat, and drink to keep going. But robots can travel to the ends of the solar system free of such constraints. They can do more, go further, and because they don't require costly life-support systems, they can do it all more often. Of course, they still require human direction. Nevertheless, we should all look for more robotic space travelers in the future.
Which of the following best rephrases the topic of the passage?

• A)The events that led to the first human space travel
• B)The reasons why robots make better space travelers than humans
• C)A comparison of early space travel modes
• D)A history of technological advances in the 20th century
