Problem:OPTIONS:
- earth
- heat
- water
- sun

Answer the following question given this paragraph: Most ecosystems get their energy from the Sun. Only producers can use sunlight to make usable energy. Producers convert the sunlight into chemical energy or food. Consumers get some of that energy when they eat producers. They also pass some of the energy on to other consumers when they are eaten. In this way, energy flows from one living thing to another. Q: Where do most ecosystems get their energy from? A:
****
A: sun

Answer the following question given this paragraph: Avian Respiration Birds have evolved a respiratory system that enables them to fly. Flying is a high-energy process and requires a lot of oxygen. Furthermore, many birds fly in high altitudes where the concentration of oxygen in low. How did birds evolve a respiratory system that is so unique? Decades of research by paleontologists have shown that birds evolved from therapods, meat-eating dinosaurs (Figure 39.14). In fact, fossil evidence shows that meat-eating dinosaurs that lived more than 100 million years ago had a similar flow-through respiratory system with lungs and air sacs. Archaeopteryx and Xiaotingia, for example, were flying dinosaurs and are believed to be early precursors of birds. Q: Birds have evolved a respiratory system that enables them to fly. flying is a high-energy process and requires a lot of this? A:
OPTIONS:
- weight
- nitrogen
- adaptation
- oxygen
oxygen

Answer the following question given this paragraph: Marsupials. Marsupials include the kangaroo, koala, and opossum. Q: Kangaroos, koala and opossums are part of what group? A:
OPTIONS:
- primates
- cephalopods
- monotremes
- marsupials

Answer: marsupials

Question: Answer the following question given this paragraph: Q: What forms the pathway of water and nutrients from roots to leaves and flower? A:
OPTIONS:
- the stamen
- the stigma
- the pistil
- the stem
Answer: the stem

input with options: Answer the following question given this paragraph: When fossil fuels burn, they release thermal energy, water vapor, and carbon dioxide. Carbon dioxide produced by fossil fuel use is a major cause of global warming. The burning of fossil fuels also releases many pollutants into the air. Pollutants such as sulfur dioxide form acid rain, which kills living things and damages metals, stonework, and other materials. Pollutants such as nitrogen oxides cause smog, which is harmful to human health. Tiny particles, or particulates, released when fossil fuels burn also harm human health. Natural gas releases the least pollution; coal releases the most (see Figure below ). Petroleum has the additional risk of oil spills, which may seriously damage ecosystems. Q: What gas produced by fossil fuel use is a major cause of global warming? A:
OPTIONS:
- helium
- hydrogen
- phosphorous
- carbon dioxide
output: carbon dioxide

Problem: OPTIONS:
- swirl
- solid
- vapor cloud
- liquid
Q: Answer the following question given this paragraph: The entropy is decreasing because a gas is becoming a liquid. Q: The entropy is decreasing because a gas is becoming a what? A:
Answer:
liquid
