Answer the following question given this paragraph: Pangaea has been breaking apart since about 250 million years ago. Divergent plate boundaries formed within the continents to cause them to rift apart. The continents are still moving apart. The Pacific is shrinking as the Atlantic is growing. The Appalachians ( Figure below ) are now on a passive margin. The mighty mountains have weathered and eroded to what they are today. Q: How many millions of years ago did pangaea begin breaking apart? A:
****
A: 250

Answer the following question given this paragraph: Weather is always changing. One day might be cold and cloudy. The next day might be warm and sunny. Even on the same day, the weather can change a lot. A beautiful morning might be followed by a stormy afternoon. Why does weather change? The main reason is moving air masses. Q: What is the main reason for weather change? A:
OPTIONS:
- climate change
- moving energy masses
- seasons
- moving air masses
moving air masses

Answer the following question given this paragraph: The combined gas law relates pressure, volume, and temperature of a gas. Q: Which law relates the pressure, volume, and temperature of a gas? A:
OPTIONS:
- directions gas law
- shifts gas law
- newton's law
- combines gas law

Answer: combines gas law

Question: Answer the following question given this paragraph: The theory of climate change is very new. In fact, scientists don't even call it a theory. But it meets the requirements. These are the things we know: (1) average global temperatures are rising, (2) greenhouse gases trap heat in the atmosphere, (3) CO 2 is released into the atmosphere when fossil fuels are burned, (4) CO 2 is a greenhouse gas, (5) more CO 2 in the atmosphere traps more heat so global temperature is rising. No information contradicts this theory, although some details have not been worked out. The theory is very effective at predicting future events, which are already taking place. This idea will be explored in detail in the chapter Atmospheric Processes . Q: Which theory helps predict future events in weather? A:
OPTIONS:
- expected change theory
- future weather theory
- carbon change theory
- climate change theory
Answer: climate change theory

input with options: Answer the following question given this paragraph: Electric generators convert mechanical energy to electric energy. The generator consists of some number of wire loops wrapped around an iron core and placed in a strong magnetic field. The loops of wire and the iron core are called the armature . The armature is mounted so that it can rotate freely inside the magnetic field. Mechanical energy is used to spin the armature in the field so that the wire loops cut across the field and produce electric current. The of this current is calculated by . Q: Electric generators convert what type of energy to electric energy? A:
OPTIONS:
- electromagnetic energy
- thermodynamic energy
- fluid energy
- mechanical energy
output: mechanical energy

Problem: OPTIONS:
- macrophages
- cilia
- platelets
- bronchioles
Q: Answer the following question given this paragraph: Asthma is a chronic illness in which the bronchioles, the tiny branches into which the bronchi are divided, become inflamed and narrow ( Figure below ). The muscles around the bronchioles contract, which narrows the airways. Large amounts of mucus are also made by the cells in the lungs. People with asthma have difficulty breathing. Their chests feel tight, and they wheeze. Asthma can be caused by different things, such as allergies. Asthma can also be caused by cold air, warm air, moist air, exercise, or stress. The most common asthma triggers are illnesses, like the common cold. Asthma is not contagious and cannot be passed on to other people. Children and adolescents who have asthma can still lead active lives if they control their asthma. Asthma can be controlled by taking medication and by avoiding contact with environmental triggers for asthma, like smoking. Q: Asthma affects what tiny branches into which the bronchi are divided? A:
Answer:
bronchioles
