Read the passage about space, then answer the question.Scientists discovered the asteroid belt, an area of the solar system between Mars and Jupiter, where the greatest number of asteroid orbits can be found.According to context clues, which best defines the underlined words?a piece of clothing to be worn in space travelan asteroid that is found on Jupitera region where many asteroids are locateda great number of asteroids in one placeRead the excerpt from A Black Hole is NOT a Hole.Have you ever watched the Sun set? After it sinks below the horizon, Earth blocks your view of it. Even though you know it’s still out there in space, you can’t see it. Any and all events on the Sun remain invisible to you for as long as it is below the horizon. If the Sun suddenly turned purple, you wouldn’t see it happen.In a similar way, once an object enters the extreme gravity zone of a black hole, the object disappears from view. Even though nothing physically blocks our sight, once the object is beyond the boundary of the zone, we cannot see what happens to it. Events beyond the black hole’s ‘horizon” are invisible to us. Because of this visual effect, scientists named the boundary the event horizon.What similarity is explained in this excerpt?The sun’s disappearance after sunset is similar to the way an object disappears near a black hole.The sun’s temperature after sunset is similar to the way an object cools near a black hole.The sun’s color after sunset is similar to the way an object changes color near a black hole.The sun’s speed after sunset is similar to the way an object changes speed near a black hole.Read the excerpt from A Black Hole is NOT a Hole.For example, imagine a fluffy snowball and a harder-packed snowball of the same size. The fluffier ball is made of less stuff. Its pull is wimpier than the pull of the densely packed ball.You can feel this difference when you hold the two snowballs in your hands. Each one presses down on your hand because of the gravitational attraction it shares with Earth. The hard-packed snowball has a stronger attraction to Earth because it is made of more material. It presses more forcefully than the fluffy one. It feels heavier.What do the differences in the two snowballs help the reader understand about gravity?Hard objects have a stronger attraction to Earth than fluffy objects.Hard objects have a weaker attraction to Earth than fluffy objects.Heavy objects have a stronger attraction to Earth than light objects.Heavy objects have a weaker attraction to Earth than light objects.Which is the best example of a writer using an informal style?Rachel quotes a professor who uses scientific terms.Tyler uses humor in his science report about ants.Adam uses charts and graphs to illustrate growth.Suzanna quotes from a college textbook.Which statement contrasts two items?Anything inside a black hole’s super-pulling zone will stay there forever.Nothing in the universe is more powerful than the force of a black hole.A whirlpool is powered with water, but a black hole is powered by gravity.A black hole powerfully pulls in dust, asteroids, stars, and even starlight.Read the excerpt from A Black Hole is NOT a Hole.According to Newton, the force of gravity is a two-way tug between any two objects. It works with anything—any matter at all. The matter can be a tiny bit of a thing, as small as a speck of stardust. It can be a huge collection of material, as gigantic as a galaxy. It can be as rigid as rock or as flimsy as flame. No matter what it is, if it’s made of matter, then it possesses the power to pull on anything else.According to context clues, which is the best definition ofgravity?a dropping objecta pull between objectsa collection of materiala rigid rockRead the excerpt from A Black Hole is NOT a Hole.The matter can be a tiny bit of a thing, as small as a speck of stardust.

No problem. With a little swish, the fish can speed up, giving itself the oomph to swim away. After putting some distance between itself and the whirlpool, the fish no longer feels the current’s inward pull.But what if the fish drifted farther in?Closer to the center of the whirlpool, the pull would grow stronger. To escape the whirlpool, the fish would have to swim faster than it had to at the edge. Even closer to the middle, if the fish couldn’t go much faster, it would find itself swept all the way in, stuck in the swirl, pulled round and round and round.A black hole works something like that whirlpool.What is being compared or contrasted in this excerpt?A comparison between a swimming fish and a black hole is being made.A comparison between a whirlpool and a black hole is being made.A contrast between a swimming fish and a black hole is being made.A contrast between a whirlpool and a black hole is being made.Which is the best example of a writer using formal writing?Emma uses short sentences in her plant report.Harrison uses simple vocabulary in his gravity essay.Mary uses technical language to explain magnetism.Mark uses humor when writing about electricity.
