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.

Which statement best defends the author’s claim with additional evidence?

A) The Curiosity rover cost more than two billion dollars to design.
B) Rovers are interesting because of how their wheels are constructed.
C) Rovers are named by the scientists at NASA when they are completed.
D) The Curiosity rover will be able to explore Mars for up to 10 years.

D) The Curiosity rover will be able to explore Mars for up to 10 years

Explanation:

In the passage it didn't mention what the actual price was, it just hinted that it was expensive to make.

It didn't say anything about how the wheel are constructed, nor who they were named by.

It did however say that Rovers are good at measuring the planet that they are on (so they can measure planets other than Earth) and they are much more durable than humans and can survive longer on a foreign planet (so they will be able to explore Mars for longer than a human could, which in this case is 10 years.)

the word that best matches the meaning of the expression "went to the big ocean" is died.

the goldfish died, which is why the father looks at the children mournfully. the "big ocean" is the father's way of saying fish heaven. he could have just said that the goldfish died, but this way, the children imagine the fish in a bigger, better place instead of just picturing a dead fish.
