Question: Answer the following question given this paragraph: The electrolysis of water produces hydrogen and oxygen gases. The electrolytic cell consists of a pair of platinum electrodes immersed in water containing a small amount of an electrolyte, such as H 2 SO 4 . The electrolyte is necessary because pure water does not contain enough ions to effectively conduct a current. At the anode, water is oxidized to oxygen gas and hydrogen ions. At the cathode, water is reduced to hydrogen gas and hydroxide ions. Q: The electrolysis of what substance produces hydrogen and oxygen gases A:
OPTIONS:
- cholesterol
- carbon dioxide
- hydrocarbon
- water
Answer: water

input with options: Answer the following question given this paragraph: Sometimes deep ocean water rises to the surface. This is called upwelling . Figure below shows why it happens. Strong winds blow surface water away from shore. This allows deeper water to flow to the surface and take its place. Q: What is the name for the term that describes deep ocean water rising the surface? A:
OPTIONS:
- percolating
- leaking
- up-rising
- upwelling
output: upwelling

Q: Answer the following question given this paragraph: Freshwater biomes are defined by their low salt concentration, usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration, such as the ocean. There are different types of freshwater biomes: ponds and lakes ( Figure below ), streams and rivers, and wetlands. Ponds and lakes range in size from just a few square meters to thousands of square kilometers. Streams and rivers are bodies of flowing water moving in one direction. They can be found everywhere. They get their starts at headwaters , which may be springs, melting snow, or even lakes, and then travel all the way to their mouths , emptying into another water channel or the ocean. Wetlands are areas of standing water that support aquatic plants. Wetlands include marshes, swamps, and bogs. Q: What are fresh water biomes defined by? A:

OPTIONS:
- high salt content
- moving water
- animal species
- low salt concentration

A: low salt concentration

input: OPTIONS:
- no energy
- high energy
- low sand density
- low energy Now, answer this question: Answer the following question given this paragraph: Waves also move sand from the beaches on shore to bars of sand offshore as the seasons change. In the summer, waves have lower energy so they bring sand up onto the beach. In the winter, higher energy waves bring the sand back offshore. Q: What causes waves to bring sand up onto the beach during summers? A:
A:
output: low energy

Answer the following question given this paragraph: Cell division is just one stage of the cell cycle. The cell cycle includes all of the stages in the life of a cell. The cell cycle is more complex in eukaryotic than prokaryotic cells. Q: What stages in the life of a cell does the cell cycle include? A:

OPTIONS:
- adult stages
- intermediate stages
- both
- all

Answer: all

Q: Answer the following question given this paragraph: Nitrogen is an essential part of many molecules needed by living organisms. Q: What element is an essential part of many molecules needed by living organisms? A:

OPTIONS:
- helium
- silicon
- hydrogen
- nitrogen

A:
nitrogen
