input: OPTIONS:
- storm front
- obscured front
- stationary front
- occluded front Now, answer this question: Answer the following question given this paragraph: With an occluded front , a warm air mass becomes trapped between two cold air masses. The warm air is lifted up above the cold air as in Figure below . Cloudy weather and precipitation along the front are typical. Q: When a warm air mass becomes trapped between two cold air masses, what type of front occurs? A:
A:
output: occluded front

Answer the following question given this paragraph: Q: Living things need to take in nutrients so that they can grow and create what? A:

OPTIONS:
- protein
- plasma
- hydrogen
- energy

Answer: energy

Problem: OPTIONS:
- light number
- spectrum
- ability
- atomic number
Q: Answer the following question given this paragraph: The atomic number of an element is the number of protons in the nucleus of each atom of that element. An atom can be classified as a particular element based solely on its atomic number. For example, any atom with an atomic number of 8 (its nucleus contains 8 protons) is an oxygen atom, and any atom with a different number of protons would be a different element. The periodic table ( Figure below ) displays all of the known elements and is arranged in order of increasing atomic number. In this table, an element's atomic number is indicated above the elemental symbol. Hydrogen, at the upper left of the table, has an atomic number of 1. Every hydrogen atom has one proton in its nucleus. Next on the table is helium, whose atoms have two protons in the nucleus. Lithium atoms have three protons, beryllium atoms have four, and so on. Since atoms are neutral, the number of electrons in an atom is equal to the number of protons. Therefore, hydrogen atoms all have one electron occupying the space outside of the nucleus. Q: An atom can be classified as a particular element based solely on its what? A:
Answer: atomic number

Problem:OPTIONS:
- air density
- moon phase
- time of day
- air temperature

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 . Below, you can see how the different types form ( Figure below ). Q: What determines which type of precipitation falls in the atmosphere? A:
****
A: air temperature

Answer the following question given this paragraph: Unlike corals, jellyfish spend most of their lives as medusae. They live virtually everywhere in the ocean. They are typically carnivores. They prey on zooplankton, other invertebrates, and the eggs and larvae of fish. Q: Unlike corals, jellyfish spend most of their lives as what? A:
OPTIONS:
- infants
- pupae
- cercariae
- medusae
medusae

Answer the following question given this paragraph: Q: How many protons do all atoms of a particular element have in their nuclei? A:
