RI.3.8 Author's Reasons and Evidence

Which statement gives a reason that supports the author's point about Mars rovers?

• A science station has a lot of capabilities.

• Vehicles like Curiosity are well-suited for exploring Mars.

• Mars rovers must be able to collect data and send it to Earth.

• Curiosity has human-like traits that will help people travel to Mars.

Choose all the evidence that best supports your answer in Part A.

Supporters of Mars exploration also point out that, as a vehicle, Curiosity can do much more than a science station that's fixed in one place. Curiosity moves- or roves- across the surface of Mars, collecting information as it goes. Its "eyes" are 17 cameras that can see and analyze the landscape. The rover's "feet" are its wheels. Those wheels roll over obstacles as high as 2.5 feet. The robot's "ears" hear commands relayed from NASA.
