Process: - Coal is harvested from a coal mine - The coal is transported either by train or truck to power station - The coal is burned in a furnace - Water is turned into steam in the boiler - The steam is cooled in cooling towers - The steam turns the turbines - The generator makes electricity - The electricity is sent through transformers. Question: suppose coal will become cheaper happens, how will it affect MORE coal arriving at the power station. - A: more - B: less - C: no effect

Answer: A
Q: Process: - An area is at a higher elevation than the surrounding area - Rain falls - Water is in the area of high elevation - The water creates a stream - The stream moves towards lower elevation - The stream continues along the same path for a long time - The soil and rocks erode where the stream touches them - The stream moves deeper into the soil - The stream is smaller than the eroded area. Question: suppose more volcanoes form happens, how will it affect MORE/LARGER ravines forming. - A: more - B: less - C: no effect
A: C
Question: Process: - As the sweat evaporates the sweat sheds molecules into the air - The sweat changes into a gas - Heat is drawn from the sweat - This process draws heat from the body - The evaporation also cools the remaining sweat on the body. Question: suppose more heat drawn from sweat happens, how will it affect LESS body cooling occurring. - A: more - B: less - C: no effect
Answer: B
[Q]: Process: - When water freezes it becomes 10% bigger, or takes up 10% more space - As water expands it puts great pressure on the walls of anything containing it, including any rocks which happen to be surrounding it - The force of the pressure exerted on the rock surrounding it is enough to wedge the walls of the crack farther apart, thus expanding and deepening the crack - Clay expends when wet like ice does - This causes rock to break apart - Some plants like mosses and lichens are capable of growing without soil on bare rock - When they do this their roots penetrate pores and crevices and cause rocks to split apart as the roots force their way down through the rocks - Question: suppose there is a drought happens, how will it affect MORE or FASTER erosion of rocks. - A: more - B: less - C: no effect

[A]: B
input: Please answer the following: Process: - Green is a color that gathers sunlight easily - Sunlight is gathered by the leaves of the plant - The sunlight is broken down into glucose through photosynthesis - The glucose travels the plant - The plant uses that glucose as energy to grow. Question: suppose more animals survive happens, how will it affect Less glucose can be produced. - A: more - B: less - C: no effect
++++++++++
output: C
Process: - Body temperature rises - The brain tells blood vessels to dilate - The sweat glands become active - Moisture is released from the pores - The moisture evaporates - The evaporation causes cooling. Question: suppose person is in freezing temperature happens, how will it affect MORE body cooling occurring. - A: more - B: less - C: no effect
