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

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

A: biodiversity

input: OPTIONS:
- mars
- jupitor
- earth
- mercury Now, answer this question: Answer the following question given this paragraph: Mercury is the smallest planet. It has no moon. It is also the planet closest to the Sun. Pictured below is the surface of Mercury covered with craters ( Figure below ), like Earth's Moon. Many of the impact craters are billions of years old. This means that Mercury hasn't changed much geologically for billions of years. It has no plate tectonics. With only a trace of an atmosphere, it has no weather to wear down the ancient craters. Q: What is the name of the smallest planet in our solar system, which is also nearest to the sun? A:
A:
output: mercury

Answer the following question given this paragraph: Hydrocarbons are molecules that contain only carbon and hydrogen atoms. Because each carbon atom can form covalent bonds with up to four other atoms, very large and complex molecules can be formed just from these two elements. Hydrocarbons in which all carbons are connected by single bonds are known as alkanes . If a C=C double bond is present, the compound is now an alkene . A triple bond between two carbons (CC) makes the compound an alkyne . Hydrocarbons can also be broadly classified as either saturated , which means they contain no multiple bonds, or unsaturated , which means they contain at least one double or triple bond. Q: Hydrocarbons in which all carbons are connected by single bonds are called? A:

OPTIONS:
- acids
- enzymes
- lipids
- alkanes

Answer: alkanes

Problem: OPTIONS:
- storage time
- latency
- presence time
- residence time
Q: Answer the following question given this paragraph: A substance is stored in a reservoir. The amount of time it stays in that reservoir is its residence time. Q: What do we call the amount of time a substance is stored in a reservoir? A:
Answer: residence time

Problem:OPTIONS:
- particles forces
- outermolecular forces
- gravitational forces
- intermolecular forces

Answer the following question given this paragraph: Thermal Expansion The intermolecular forces in liquids are strong enough to keep them from expanding significantly when heated (typically only a few percent over a 100C temperature range). Thus the volumes of liquids are somewhat fixed. Notice from Table 11.1 "The Density of Water at Various Temperatures" that the density of water, for example, changes by only about 3% over a 90-degree temperature range. Table 11.1 The Density of Water at Various Temperatures. Q: What forces in liquids are strong enough to keep them from expanding significantly when heated? A:
****
A: intermolecular forces

Problem:OPTIONS:
- pressure
- cooling
- heating
- energy

Answer the following question given this paragraph: Passive transport does not require energy input. Q: What type of input is not required during passive transport? A:
****
A:
energy
