What is one reason people used to think that nothing could live deep down in the ocean? A B C D There was no sunlight there. Some bacteria make food from sulfur. Europa has very large oceans. Life is extremely adaptable. 2. What does this passage describe? A B C D This passage describes the process of photosynthesis and all the plants that use it. This passage describes the importance of camels to other animals living in the desert. This passage describes life deep in the ocean and the process of natural selection. This passage describes the formation and discovery of hydrothermal vents. 3. Read the following sentences: “Some animals that live in places where it is very snowy, like high in the mountains or in the arctic, end up white, so that they fit in better. Animals and plants that live in the desert, like cacti and camels, have evolved so that they need only the very little water that they get living there.” What can be concluded from this information? A B C D Animals are better suited to living in the desert than in places where it is very snowy. Plants evolve more quickly than animals do. Animals evolve more quickly than plants do. Animals and plants change over time based on where they live. 4. What is a result of the discovery of life deep in the ocean? A B C D Scientists Scientists Scientists Scientists realized that sulfur is poisonous to most living things on earth. realized that life can exist in places without sunlight and oxygen. became confident that nothing could live around a hydrothermal vent. learned that sunlight is necessary for the process of photosynthesis. 5. What is the main idea of this passage? A B C D For many years scientists thought that nothing could live near a hydrothermal vent. Life is extremely adaptable and can be found even in harsh environments. Some bacteria use sulfur to make food in a process known as chemosynthesis. Scientists now think that life may exist on Europa, one of Jupiter’s moons. 1 © 2013 ReadWorks®, Inc.

Scientists now know that life exists deep in the ocean; _______, they thought that nothing could live there. A B C D for example therefore previously currently 8.
