Background: An electric generator is a device that changes kinetic energy to electrical energy through electromagnetic induction. A simple diagram of an electric generator is shown in Figure below . In a generator, some form of energy is applied to turn a shaft. This causes a coil of wire to rotate between opposite poles of a magnet. Because the coil is rotating in a magnetic field, electric current is generated in the wire. If the diagram in Figure below looks familiar to you, that's because a generator is an electric motor in reverse. Look back at the electric motor in Figure above . If you were to mechanically turn the shaft of the motor (instead of using electromagnetism to turn it), the motor would generate electricity just like an electric generator. You can learn how to make a very simple electric generator by watching the video at the URL below. Making your own generator will help you understand how a generator works. Paragraph: A windmill is used to power a nearby house. On days when there is almost no wind the house runs very low on power. But on days when there is a lot of wind, such as during a storm the reserve batteries for the house are able to charge to full. Given the paragraph above, please answer correctly the following question: Given the levels of the batteries are very low, has the amount of wind in the area increased or decreased?
----
Answer: decreased

Background: Magnetism is due to the movement of electrons within atoms of matter. When electrons spin around the nucleus of an atom, it causes the atom to become a tiny magnet, with north and south poles and a magnetic field. In most materials, the electrons orbiting the nuclei of the atoms are arranged in such a way that the materials have no magnetic properties. Also, in most types of matter, the north and south poles of atoms point in all different directions, so overall the matter is not magnetic. Examples of nonmagnetic materials include wood, glass, plastic, paper, copper, and aluminum. These materials are not attracted to magnets and cannot become magnets. Paragraph: Andy has a refrigerator in his house with lots of magnets on it as decorations. One day while playing with and rearranging them he decided to see what other metals around his kitchen they would stick to. The things he had available were copper pots and pans, aluminum foil and some wooden spatulas. Given the paragraph above, please answer correctly the following question: Will most types of matter be magnetic or not magnetic?
----
Answer: not magnetic

Background: Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically 2060 micrometres (0.00080.0024 in) in diameter, although the pollen grains of Pinus species can be much larger and much less dense. Anemophilous plants possess well-exposed stamens so that the pollens are exposed to wind currents and also have large and feathery stigma to easily trap airborne pollen grains. Pollen from anemophilous plants tends to be smaller and lighter than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher-protein pollens from entomophilous flowers are scarce. Anemophilous pollens may also be inadvertently captured by bees' electrostatic field. This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently gathering pollen from corn tassels and other grains. Paragraph: Two botanists studied different types of plants. Barb studied anemophilous plants, while her friend Faye learned about entomophilous plants. Given the paragraph above, please answer correctly the following question: Which botanist learned less about the pollen grains of Pinus species?
----
Answer:
Faye
