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 is true according to information found in the passage?

The author states "At the dawn of the space age, space travel required human astronauts-they were simply more capable than robots."
Robots are more expensive to send into space than humans is incorrect. The author states "because (robots) don't require costly life-support systems," they can travel more often into space. We can guess from this that they cost less than humans to send into space. 
Robots that are used to explore space don't need guidance from humans is incorrect. The author states that "they still require human direction." 
Humans developed the technology that is needed to breathe, eat, and drink in space is incorrect. Of course, this is a true statement. But the author does not state this to directly. He only says that "Astronauts have to breathe, eat, and drink to keep going."
