Question: Answer the following question given this paragraph: The figure below shows why tides occur ( Figure below ). The main cause of tides is the pull of the Moon's gravity on Earth. The pull is greatest on whatever is closest to the Moon. Although the gravity pulls the land, only the water can move. As a result:. Q: The pull of the moon's gravity on earth is the main cause of what water phenomenon? A:
OPTIONS:
- storms
- floods
- waves
- tides
Answer: tides

input with options: Answer the following question given this paragraph: The theory of evolution by natural selection explains how populations of organisms can change over time. As environments change, so must the traits of organisms if they are to survive in the new conditions. Evolution by natural selection explains how this happens. It also explains why there are so many different species of organisms on Earth today. You can see examples of the incredible diversity of living animals in Figure below . You can read more about the theory of evolution in the chapter Evolution. Q: Which theory explains how populations of organisms can change over time? A:
OPTIONS:
- free by natural selection
- changes by natural selection
- intelligent selection
- evolution by natural selection
output: evolution by natural selection

Q: Answer the following question given this paragraph: The crystal structure of ionic compounds is strong and rigid. It takes a lot of energy to break all those ionic bonds. As a result, ionic compounds are solids with high melting and boiling points. You can see the melting and boiling points of several different ionic compounds in the Table below . To appreciate how high they are, consider that the melting and boiling points of water, which is not an ionic compound, are 0C and 100C, respectively. Q: In celsius, what is the boiling point of water? A:

OPTIONS:
- zero degrees
- two hundred twelve degrees
- ninety eight degrees
- one hundred degrees

A: one hundred degrees

input: OPTIONS:
- Allopatric speciation
- interconnection
- spontaneous mutation
- coevolution Now, answer this question: Answer the following question given this paragraph: Two species may often interact with each other and have a close relationship. Examples include flowers and the animals that pollinate them. When one of the two species evolves new traits, the other species may evolve matching traits. This is called coevolution . You can see an example of this in Figure below . The very long beak of this hummingbird co-evolved with the tubular flowers it pollinates. Only this species of hummingbird can reach nectar deep in the flowers. Q: What is it called when two species evolve matching traits? A:
A:
output: coevolution

Answer the following question given this paragraph: Earth is a round, three-dimensional ball. In a small area, Earth looks flat, so it is not hard to make accurate maps of a small place. When mapmakers want to map the round Earth on flat paper, they use projections. What happens if you try to flatten out the skin of a peeled orange? Or if you try to gift wrap a soccer ball? To flatten out, the orange peel must rip, and its shape must become distorted. To wrap a round object with flat paper requires lots of extra cuts and folds. A projection is a way to represent Earth's curved surface on flat paper ( Figure below ). Q: What method is used to map the earth on flat paper? A:

OPTIONS:
- calculations
- forecasts
- surveying
- projections

Answer: projections

Q: Answer the following question given this paragraph: Though the above fruit may not result, it would be nice to scientifically predict what would result. Predicting the possible genotypes and phenotypes from a genetic cross is often aided by a Punnett square. Q: Predicting the possible genotypes and phenotypes from a genetic cross is often aided by a what? A:

OPTIONS:
- balusters square
- dinobot square
- axle square
- punnett square

A:
punnett square
