Answer the following question given this paragraph: Radon is also radioactive and can easily be inhaled into the lungs. Over time, this internal radon exposure can lead to the development of lung cancer. The incidence of lung cancer in smokers exposed to radon is much higher than that in non-smokers exposed to radon since smoking has already produced some lung damage, and the radon simply makes the damage worse. Radon exposure is highest in homes lacking good air circulation to move the gas out of the residence. There are a number of inexpensive approaches to decreasing your exposure to radon. A good start is to test your living area for radon with a radon test kit. Q: Smoking increases the risk of cancer from what radioactive gas that can also be detected with a test kit for your home? A:
OPTIONS:
- arsenic
- carbon monoxide
- carbon dioxide
- radon

Answer: radon

Question: Answer the following question given this paragraph: Earth's gravity also affects the acceleration of objects that start out moving horizontally, or parallel to the ground. Look at Figure below . A cannon shoots a cannon ball straight ahead, giving the ball horizontal motion. At the same time, gravity pulls the ball down toward the ground. Both forces acting together cause the ball to move in a curved path. This is called projectile motion . Q: Which factor causes a cannon ball to move horizontally and then fall on the ground? A:
OPTIONS:
- cone motion
- fluid motion
- downward motion
- projectile motion
Answer: projectile motion

input with options: Answer the following question given this paragraph: In physics, resistance is opposition to the flow of electric charges in an electric current as it travels through matter. The SI unit for resistance is the ohm. Resistance occurs because moving electrons in current bump into atoms of matter. Resistance reduces the amount of electrical energy that is transferred through matter. That's because some of the electrical energy is absorbed by the atoms and changed to other forms of energy, such as heat. You can see an animation of resistance at the level of atoms and electrons at this URL: http://www. physics. org/explorelink. asp?id=1738&q=electricalresistance&currentpage=1&age=0&knowledge=0&item=3. Q: In physics, resistance is opposition to the flow of what? A:
OPTIONS:
- temperature charges
- capacitance
- surface flow
- electrical charges
output: electrical charges

Q: Answer the following question given this paragraph: Some bacteria depend on other organisms for survival. For example, some bacteria live in the roots of legumes, such as pea plants ( Figure below ). The bacteria turn nitrogen-containing molecules into nitrogen that the plant can use. Meanwhile, the root provides nutrients to the bacteria. In this relationship, both the bacteria and the plant benefit, so it is known as a mutualism . Q: In biology, a relationship that benefits both entities is known as what? A:

OPTIONS:
- naturalism
- altruism
- predatory
- mutualism

A: mutualism

input: OPTIONS:
- microwave
- kinetic
- atomic
- nuclear Now, answer this question: Answer the following question given this paragraph: Nuclear energy is released when the nucleus of an atom is split. Q: What kind of energy is released when the nucleus of an atom is split? A:
A:
output: nuclear

Question: Answer the following question given this paragraph: 21.3 Preserving Biodiversity Five mass extinctions with losses of more than 50 percent of extant species are observable in the fossil record. Recent extinctions are recorded in written history and are the basis for one method of estimating contemporary extinction rates. The other method uses measures of habitat loss and species-area relationships. Estimates of contemporary extinction rates vary but are as high as 500 times the background rate, as determined from the fossil record, and are predicted to rise. There is a legislative framework for biodiversity protection. International treaties such as CITES regulate the transportation of endangered species across international borders. Legislation within individual countries protecting species and agreements on global warming have had limited success; there is at present no international agreement on targets for greenhouse gas emissions. In the United States, the Endangered Species Act protects listed species but is hampered by procedural difficulties and a focus on individual species. The Migratory Bird Act is an agreement between Canada and the United States to protect migratory birds. The non-profit sector is also very active in conservation efforts in a variety of ways. Conservation preserves are a major tool in biodiversity protection. Presently, 11 percent of Earth's land surface is protected in some way. The science of island biogeography has informed the optimal design of preserves; however, preserves have limitations imposed by political and economic forces. In addition, climate change will limit the effectiveness of present preserves in the future. A downside of preserves is that they may lessen the pressure on human societies to function more sustainably outside the preserves. Habitat restoration has the potential to restore ecosystems to previous biodiversity levels before species become extinct. Examples of restoration include reintroduction of keystone species and removal of dams on rivers. Zoos have attempted to take a more active role in... Q: Removal of dams on rivers is an example of what? A:
OPTIONS:
- evolution
- reproduction
- renewal
- restoration
Answer:
restoration
