Problem: OPTIONS:
- air pressure
- air currents
- ground temperature
- air temperature
Q: Answer the following question given this paragraph: Why does it snow instead of rain? Air temperature determines which type of precipitation falls. Rain falls if the air temperature is above freezing (0 C or 32 F). Frozen precipitation falls if the air or ground is below freezing. Frozen precipitation may fall as snow, sleet, or freezing rain. You can see how the different types form in Figure below . Q: What determines which type of precipitation falls? A:
Answer: air temperature

Problem:OPTIONS:
- the earth's gravity
- the sun
- transportation
- biodiversity

Answer the following question given this paragraph: Q: Habitat loss, introduced species, overharvesting, and global change are major threats to what? A:
****
A: biodiversity

Answer the following question given this paragraph: If you look at your hand, what do you see? Of course, you see skin, which consists of cells. But what are skin cells made of? Like all living cells, they are made of matter. In fact, all things are made of matter. Matter is anything that takes up space and has mass. Matter, in turn, is made up of chemical substances. In this lesson you will learn about the chemical substances that make up living things. Q: What term is used to describe anything that takes up space and has mass? A:
OPTIONS:
- size
- weight
- opacity
- matter
matter

Answer the following question given this paragraph: Winds on Earth are either global or local. Global winds blow in the same directions all the time. They are created when more solar energy strikes the Equator than the polar regions. More about global wind patterns is described in detail in the concept "Global Wind Belts. ". Q: What type of winds are created when more solar energy strikes the equator than the polar regions? A:
OPTIONS:
- arctic winds
- equatorial winds
- domestic winds
- global winds

Answer: global winds

Question: Answer the following question given this paragraph: Chemical energy is stored in wood and released when the wood burns. Q: When wood is burned what kind of energy allows the wood to burn? A:
OPTIONS:
- physical
- radiation
- carbon
- chemical
Answer: chemical

input: OPTIONS:
- novel
- important
- metal
- noble Now, answer this question: Answer the following question given this paragraph: A common way to keep track of valence electrons is with Lewis electron dot structures . In an electron dot structure, each atom is represented by its chemical symbol, and each valence electron is represented by a single dot. Note that only valence electrons are shown explicitly in these diagrams. For the main group elements, the number of valence electrons for a neutral atom can be determined by looking at which group the element belongs to. In the s block, Group 1 elements have one valence electron, while Group 2 elements have two valence electrons. In the p block, the number of valence electrons is equal to the group number minus ten. Group 13 elements have three valence electrons, Group 14 elements have four, and so on. The noble gases in Group 18 have eight valence electrons, and the full outer s and p sublevels are what give these elements their special stability. Representative dot diagrams are shown in the Figure below :. Q: The group 18 gases that have 8 valence electrons are referred to as what type of gases? A:
A:
output:
noble
