1. What explains the apparent size of the moon?

• a. The moon is a very large object, so it is easy to see.

• b. The moon is not too far away from Earth, so it looks big.

• c. The moon revolves around the earth, so sometimes it looks very

2. Part A: Which statement best expresses the views of scientists

about the moon:

• a. Scientists doubt that the moon was formed when an asteroid

  struck Earth.

• b. Scientists believe that the moon was formed when an asteroid

  struck Earth.

• c. Scientists wonder if the moon was formed when an asteroid

  struck Earth.

• d. Scientists know that the moon was formed when an asteroid

  struck Earth.

Part B. What evidence supports the correct answer for Part A?

• a. Scientists know the moon is “240,000 miles away,” so an

  asteroid on Earth could not affect the moon.

• b. The statement comes right after the sentence, “Many scientists

  believe the moon formed about 4.6 billion years ago” and

  explains one theory.

• c. The text says that the “moon has been a perpetual source of

  wonder from ancient times to today.”

• d. The text says, “The evidence appears all over its dusty surface,”

  so the scientists know exactly what happened.

3. Reread the following sentence:

"But, since it’s only 240,000 miles away, a relatively short

distance when compared with the vastness of space, nothing

looms larger in the night sky."

How does the sentence clarify the meaning of the word

vastness?

• a. The sentence describes 240,000 miles as a “short distance

  when compared with the vastness of space,” so vastness might

  mean “having a very large size.”

• b. The sentence describes the distance between the earth and the

  moon as a “relatively short distance,” so vastness might mean

  “having a small size.”

• c. The sentence says “nothing looms larger in the night sky,”

  than the moon, which is very bright, so vastness might mean

  “brightness.”

• d. The sentence says “nothing looms larger in the night sky,” and

  the night sky is very dark, so vastness might mean “darkness.”

4. What is the correct sequence of events for one theory that explains

how the moon was formed?

• a. First, fragments of rock formed the moon, then the fragments

  orbited the earth, and finally, an asteroid hit the earth.

• b. First, fragments of rock orbited the earth, then an asteroid hit

  the earth, and finally, the fragments of rock formed the moon.

• c. First, an asteroid hit the earth, then the fragments of rock came

  together to form the moon, and finally, the fragments began

  orbiting the earth.

• d. First, an asteroid hit the earth, then fragments of rock orbited

  the planet, and finally, the fragments came together to form

  the moon.

5. What is the function of the word "since" in the following sentence?

Since it has little if any atmosphere to protect it, the moon has

been, and continues to be, bombarded by space debris.

• a. Since explains the sequence of events: first the moon lost its

  atmosphere, and then it was bombarded by space debris.

• b. Since explains a cause-and-effect relationship: because space

  debris bombards the moon, it has no atmosphere.

• c. Since explains a cause-and-effect relationship: because the

  moon has no atmosphere, space debris bombards it.

• d. Since explains the sequence of events: from the time the moon

  lost its atmosphere, space debris has bombarded it.

6. Which sentence from the text best describes this diagram?

• a. When the moon is directly between the earth and the sun, light

  falls on the far side of the moon, blocked from Earth’s view.

• b. When the moon is on the far side of the earth, away from the

  sun, the moon is fully illuminated, or full.

• c. As the moon travels around the earth, we can only see the

  sunlight falling on part of it, resulting in crescent moons and

  half moons.

• d. On rare occasions, a full moon passes through Earth’s shadow,

  and the sun’s light is blocked.
