A friend says she saw a planet shining on her meridian at midnight. Which planet can you be sure that she did not see?
 
  A) Venus
  B) Mars
  C) Jupiter
  D) Saturn

Question 2

Which statement below is true?
 
  A) If we could build a spaceship capable of traveling at a speed very near the speed of light, passengers on the ship could make a journey to a star that is 500 light-years away within their lifetimes.
  B) If we could build a spaceship capable of traveling at a speed very near the speed of light, we could send a ship to a star that is 500 light-years away and it would return just a few years after we launched it.
  C) Thanks to effects of special relativity, we could build a spaceship that could go close to the speed of light with much less fuel than we would have guessed from Newton's laws of motion.
  D) Because special relativity tells us that we cannot reach or exceed the speed of light, it means that distant stars will never be within our reach because the time required to reach them will always be quite long, even with very fast spaceships.
