input: OPTIONS:
- in to out
- left to right
- low to high
- high to low Now, answer this question: Answer the following question given this paragraph: Cold air is dense, so it sinks. This creates a center of high pressure. Warm air is less dense so it rises. This creates a center of low pressure. Air always flows from higher to lower pressure. As the air flows, Earth's surface rotates below it causing Coriolis effect. So while the wind blows into the low pressure, it revolves in a circular pattern. This wind pattern forms a cyclone. The same happens while the wind blows out of a high pressure. This forms an anticyclone. Both are shown in Figure below . Q: How does air always flow? A:
A:
output: high to low

Answer the following question given this paragraph: Electrons at lower energy levels, which are closer to the nucleus, have less energy. At the lowest energy level, which has the least energy, there is just one orbital, so this energy level has a maximum of two electrons. Q: What happens to the energy levels of electrons as they are closer to the nucleus? A:

OPTIONS:
- they are higher
- they balance
- they divide
- they are lower

Answer: they are lower

Problem: OPTIONS:
- gas
- plasma
- theoretical
- biochemical
Q: Answer the following question given this paragraph: Biochemical reactions are optimal at physiological temperatures. For example, most biochemical reactions work best at the normal body temperature of 98.6F. Many enzymes lose function at lower and higher temperatures. At higher temperatures, an enzyme's shape deteriorates. Only when the temperature comes back to normal does the enzyme regain its shape and normal activity. Q: Normal body temperature is ideal for most of what type of reactions? A:
Answer: biochemical

Problem:OPTIONS:
- insects
- mammals
- dinosaurs
- aquatic

Answer the following question given this paragraph: The partial geologic time scale in Figure below shows when some of the major events in animal evolution took place. The oldest animal fossils are about 630 million years old, so presumably animals evolved around that time or somewhat earlier. The earliest animals were aquatic invertebrates. The first vertebrates evolved around 550 million years ago. By 500 million years ago, most modern phyla of animals had evolved. The first terrestrial animals evolved about 50 million years after that. Q: The earliest animals were which kind of invertebrates? A:
****
A: aquatic

Answer the following question given this paragraph: Q: Foresters commonly inoculate pine seedlings with a type of what to promote growth? A:
OPTIONS:
- yeast
- soil
- proteins
- fungi
fungi

Answer the following question given this paragraph: Scientific investigations involve the collection of data through observation, the formation and testing of hypotheses by experimentation, and analysis of the results that involves reasoning. Scientific investigations begin with observations that lead to questions. Q: What is the initial stage of scienetific investigations? A:
OPTIONS:
- asking questions
- forming hypothesis
- making predictions
- observation

Answer:
observation
