Which statement best defends the author's claim with
additional evidence?
Read the passage.
Rovers are the best way to explore other planets. By
sending rovers into space, we can learn about the universe
without having to send people. Rovers are good at gathering
information and measuring the planet they are on. They are
also much more durable than humans and can survive
much longer on a foreign planet. They are expensive to
make, but the information they send back to Earth is worth
the money it takes to build them.
The Curiosity rover cost more than two billion dollars to
design.
Rovers are interesting because of how their wheels are
constructed.
Rovers are named by the scientists at NASA when they
are completed
The Curiosity rover will be able to explore Mars for up to
10 years.
