input with options: Answer the following question given this paragraph: Using fossil fuels affects the environment in a variety of ways. There are impacts to the environment when we extract these resources. Burning these fuels causes air pollution. These fuels release carbon dioxide, which is a major factor in global warming ( Figure below ). Q: What gas is released by burning of fossil fuels and contributes to global warming? A:
OPTIONS:
- nitrous oxide
- hydrogen
- helium
- carbon dioxide
output: carbon dioxide

Q: Answer the following question given this paragraph: Work is defined differently in physics than in everyday language. In physics, work means the use of force to move an object. The teen who is playing tennis in Figure above is using force to move her tennis racket, so she is doing work. The teen who is studying isn't moving anything, so she is not doing work. Q: What term in physics refers to the use of force to move an object? A:

OPTIONS:
- mass
- momentum
- velocity
- work

A: work

input: OPTIONS:
- inorganic compounds
- amino acids
- hydrocarbons
- organic compounds Now, answer this question: Answer the following question given this paragraph: In just the right combinations, you get life. Carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. Some of the most basic of elements, but some of the most important. Together they can form countless combinations of organic compounds. And in just the right combinations, anything can happen. Q: Carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur are basic elements that form what type of compounds, which are vital to life? A:
A:
output: organic compounds

Q: Answer the following question given this paragraph: 10.7 Cardiac Muscle Tissue Cardiac muscle is striated muscle that is present only in the heart. Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts. Contraction in each cardiac muscle fiber is triggered by Ca++ ions in a similar manner as skeletal muscle, but here the Ca++ ions come from SR and through voltage-gated calcium channels in the sarcolemma. Pacemaker cells stimulate the spontaneous contraction of cardiac muscle as a functional unit, called a syncytium. Q: Pacemaker cells stimulate the spontaneous contraction of cardiac muscle as a functional unit, called a what? A:
Answer: syncytium

Answer the following question given this paragraph: An ionic bond is the force of attraction that holds together oppositely charged ions. Ionic bonds form crystals instead of molecules. Table salt contains ionic bonds. Q: What term means the force of attraction that holds together oppositely charged ions? A:

OPTIONS:
- electron bond
- magnetic bond
- solvent bond
- ionic bond

Answer:
ionic bond
