Answer the following question given this paragraph: Frost is solid water that forms when water vapor undergoes deposition. Q: What is solid water that forms when water vapor undergoes deposition? Choices: - distillate - glacier - dew - frost A:
frost
Answer the following question given this paragraph: The lymphatic system also plays an important role in the immune system. For example, the lymphatic system makes white blood cells that protect the body from diseases. Cells of the lymphatic system produce two types of white blood cells, T cells and B cells, that are involved in fighting specific pathogens. Lymph nodes, which are scattered throughout the lymphatic system, act as filters or traps for foreign particles and are important in the proper functioning of the immune system. The role of the lymphatic system in the immune response is discussed in additional concepts. Q: What system in the human body makes white blood cells that protect the body from diseases? Choices: - cardiovascular system - renal system - reproductive system - lymphatic system A:
lymphatic system
Q: Answer the following question given this paragraph: Q: How much time does the moon take to complete one revolution around the earth? Choices: - one year - one day - one week - one month A:
A: one month
Question: Answer the following question given this paragraph: Making Connections: Cosmology and Particle Physics There are many connections of cosmologyby definition involving physics on the largest scalewith particle physicsby definition physics on the smallest scale. Among these are the dominance of matter over antimatter, the nearly perfect uniformity of the cosmic microwave background, and the mere existence of galaxies. Matter versus antimatter We know from direct observation that antimatter is rare. The Earth and the solar system are nearly pure matter. Space probes and cosmic rays give direct evidencethe landing of the Viking probes on Mars would have been spectacular explosions of mutual annihilation energy if Mars were antimatter. We also know that most of the universe is dominated by matter. This is proven by the lack of annihilation radiation coming to us from space, particularly the relative absence of 0.511-MeV rays created by the mutual annihilation of electrons and positrons. It seemed possible that there could be entire solar systems or galaxies made of antimatter in perfect symmetry with our matter-dominated systems. But the interactions between stars and galaxies would sometimes bring matter and antimatter together in large amounts. The annihilation + radiation they would produce is simply not observed. Antimatter in nature is created in particle collisions and in decays, but only in small amounts that quickly annihilate, leaving almost pure matter surviving. Particle physics seems symmetric in matter and antimatter. Why isn't the cosmos? The answer is that particle physics is not quite perfectly symmetric in this regard. The decay of one of the neutral K -mesons, for example, preferentially creates more matter than antimatter. This is caused by a fundamental small asymmetry in the basic forces. This small asymmetry produced slightly. Q: The lack of annihilation radiation coming to us from space proves that the universe is dominated by what? Choices: - vacuum - energy - space - matter A:
Answer: matter

Answer the following question given this paragraph: Nearsightedness, or myopia, is the condition in which nearby objects are seen clearly, but distant objects appear blurry. The Figure below shows how it occurs. The eyeball is longer (from front to back) than normal. This causes images to be focused in front of the retina instead of on the retina. Myopia can be corrected with concave lenses. The lenses focus images farther back in the eye, so they fall on the retina instead of in front of it. Q: What is another term for nearsightedness? Choices: - hypoxia - astigmatism - anemia - myopia A:
(A).
myopia
