Answer the following question given this paragraph: Polar compounds, such as water, are compounds that have a partial negative charge on one side of each molecule and a partial positive charge on the other side. All polar compounds contain polar bonds (although not all compounds that contain polar bonds are polar. ) In a polar bond, two atoms share electrons unequally. One atom attracts the shared electrons more strongly, so it has a partial negative charge. The other atom attracts the shared electrons less strongly, so it is has a partial positive charge. In a water molecule, the oxygen atom attracts the shared electrons more strongly than the hydrogen atoms do. This explains why the oxygen side of the water molecule has a partial negative charge and the hydrogen side of the molecule has a partial positive charge. Q: All polar compounds contain what type of bonds? A:

OPTIONS:
- balanced
- strong
- weak
- polar

Answer: polar

Problem: OPTIONS:
- atom

Answer the following question given this paragraph: Blood vessels help regulate body processes by either constricting (becoming narrower) or dilating (becoming wider). These actions occur in response to signals from the autonomic nervous system or the endocrine system. Constriction occurs when the muscular walls of blood vessels contract. This reduces the amount of blood that can flow through the vessels (see Figure below ). Dilation occurs when the walls relax. This increases blood flows through the vessels. Q: What structures of the cardiovascular system help regulate body processes by either constricting or dilating? A:
OPTIONS:
- muscles
- cartilage
- capillaries
- blood vessels
blood vessels

Answer the following question given this paragraph: Accuracy is how close a measurement is to the true value. For example, 66 mL is a fairly accurate measurement of the liquid in Figure above . Q: What is the term for how close a measurement is to the true value? A:
OPTIONS:
- frequency
- validity
- correctness
- accuracy

Answer: accuracy

input with options: Answer the following question given this paragraph: A: With greater reflection off the ionosphere, AM waves can travel even farther at night than they can during the day. Radio receivers can often pick up radio broadcasts at night from cities that are hundreds of miles away. Q: Greater reflection off what atmospheric layer allows am radio waves to travel even farther at night than they can during the day? A:
OPTIONS:
- stratosphere
- exosphere
- troposphere
- ionosphere
output:
ionosphere
