Q: Answer the following question given this paragraph: Electromotive Force You can think of many different types of voltage sources. Batteries themselves come in many varieties. There are many types of mechanical/electrical generators, driven by many different energy sources, ranging from nuclear to wind. Solar cells create voltages directly from light, while thermoelectric devices create voltage from temperature differences. Q: Solar cells create voltages directly from light, while thermoelectric devices create voltage from differences in what? A:
Answer: temperature

Problem:OPTIONS:
- taste
- touch
- hearing
- smell

Answer the following question given this paragraph: Primates usually rely more on the sense of vision rather than the sense of smell, which is the dominant sense in many other mammals. The importance of vision in primates is reflected by the bony socket that surrounds and protects the primate eye. Primates have widely spaced eyes in the same plane that give them stereoscopic (3-D) vision, needed for judging distances. Some primates, including humans, have also evolved color vision. Q: The anatomy of primate eyes shows they tend to rely more on vision than what sense, which is dominant in many other mammals? A:
****
A: smell

Answer the following question given this paragraph: Archimedes' law explains why some objects float in fluids even though they are very heavy. It all depends on how much fluid they displace. The cruise ship pictured in the opening image is extremely heavy, yet it stays afloat. If a steel ball with the same weight as the ship were placed in water, it would sink to the bottom. This is modeled in the Figure below . The reason the ball sinks is that its shape is very compact, so it displaces relatively little water. The volume of water displaced by the steel ball weighs less than the ball itself, so the buoyant force is not as great as the force of gravity pulling down on the ball. Thus, the ball sinks. Q: What law explains why some objects float and some sink. A:
OPTIONS:
- newton's law
- montenegrins ' law
- flanges ' law
- archimedes' law
archimedes' law

Answer the following question given this paragraph: An ionic bond is the force of attraction that holds together oppositely charged ions. It forms when atoms of a metal transfer electrons to atoms of a nonmetal. When this happens, the atoms become oppositely charged ions. Q: What bond is the force of attraction that holds together oppositely charged ions? A:
OPTIONS:
- magnetic
- iconic
- harmonic
- ionic

Answer: ionic

input with options: Answer the following question given this paragraph: Monotreme reproduction is the least risky for the mother. However, eggs are harder to protect than is an embryo or a fetus in a pouch or uterus. Therefore, monotreme offspring may have a lower chance of surviving than the offspring of therian mammals. Q: What kind of mammalian reproduction is risky for the offspring but not the mother? A:
OPTIONS:
- asexual
- sexual
- cactaceae
- monotreme
output:
monotreme
