Answer the following question given this paragraph: Most mid-ocean ridges are located deep below the sea. The island of Iceland sits right on the Mid-Atlantic ridge ( Figure below ). Q: On which ridge does iceland sit? Choices: - Arctic circle - Antarctic ridge - Pacific rim - mid-atlantic ridge A:
mid-atlantic ridge
Answer the following question given this paragraph: The ancestor of plants is green algae. This picture shows a close up of algae on the beach. Q: Name the plant considered to be the ancestor of plants? Choices: - brown algae - ferns - grass - green algae A:
green algae
Q: Answer the following question given this paragraph: One dimensional motion describes objects moving in straight lines. Speed is a scalar measure of how quickly an object is moving along this line. Velocity is speed with a direction, making it a vector. If an object's velocity changes with time, the object is said to be accelerating. When restricted to one dimension, there are only two possible directions for the velocity and acceleration vectors to point in. As we'll see in the next chapters, understanding an object's acceleration is the key to understanding its motion. Q: What is the term for a scalar measure of how quickly an object is moving along this line? Choices: - velocity - motion - force - speed A:
A: speed
Question: Answer the following question given this paragraph: Conditioning is a way of learning that involves a reward or punishment. Did you ever train a dog to fetch a ball or stick by rewarding it with treats? If you did, you were using conditioning. Another example of conditioning is shown in the video below; the rats have been taught to "play basketball" by being rewarded with food pellets. What do you think would happen if the rats were no longer rewarded for this behavior?. Q: What is the name for a way of learning that involves reward or punishment? Choices: - subjective - instinct - objective - conditioning A:
Answer: conditioning

Answer the following question given this paragraph: Geology is the study of the solid Earth. Geologists study how rocks and minerals form. The way mountains rise up is part of geology. The way mountains erode away is another part. Geologists also study fossils and Earth's history. There are many other branches of geology. There is so much to know about our home planet that most geologists become specialists in one area. For example, a mineralogist studies minerals, as seen in ( Figure below ). Q: What is the name of the scientific field that deals with the general study of the solid earth? Choices: - astronomy - physics - chemistry - geology A:
**Answer**
geology
Q: Answer the following question given this paragraph: Within a nebula, there are varying regions where gravity has caused the gas and dust to clump together. The gravitational attraction of these clumps pull more atoms into the clump. As this accretion continues, the gas pressure increases and the core of the protostar gets hotter and hotter. If the protostar gets dense enough and hot enough, a fusion reaction will ignite and the star lights up. The minimum mass for the formation of a star is about 80 times the mass of Jupiter. A star is a very large, very hot ball of gas which has hydrogen fusing into helium in the core. Stars spend the majority of their life fusing hydrogen into helium. When the hydrogen is nearly used up, the star can fuse helium into heavier elements. Throughout this process, a battle goes on in the core of the star between gravity trying to collapse the star and temperature-produced gas pressure pushing the material in the star outward. During the life of a star, there is a balance between the gas pressure pushing out and gravity pushing in. Q: When the hydrogen is nearly used up, the star can fuse which element into heavier elements? Choices: - carbon - xenon - oxygen - helium A:
A: helium
