input with options: Answer the following question given this paragraph: Carrying this one step further, we note that the slope of a velocity versus time graph is acceleration. Slope is rise divided by run; on a v vs. t graph, rise = change in velocity v and run = change in time t . The Slope of v vs. t The slope of a graph of velocity. Q: Rise divided by run is called what? A:
OPTIONS:
- hill
- steep
- mound
- slope
output: slope

Q: Answer the following question given this paragraph: A chemical bond is a force of attraction between atoms or ions. Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions. Valence electrons are the basis of all chemical bonds. For a video introduction to chemical bonds, go to this URL: http://www. youtube. com/watch?v=CGA8sRwqIFg . Q: What forms when atoms share or transfer valence electrons? A:

OPTIONS:
- replicas
- levels
- fusion
- bonds

A: bonds

input: OPTIONS:
- fungus
- moss
- aquifers
- soil Now, answer this question: Answer the following question given this paragraph: Without weathering, we would not have any soil on Earth. People could not live on Earth without soil! Your life and the lives of most organisms depend on soil. Soil is only a very thin layer over solid rock. Yet, it is the place where reactions between solid rock, liquid water and air take place. We get wood, paper, cotton, medicines, and even pure water from soil. So soil is a very important resource. Our precious soil needs to be carefully managed and cared for. If we don't take care of the soil we have, we may not be able to use it in the future. Q: Weathering is fundamental to the creation of what, which exists as a very thin layer over solid rock? A:
A:
output: soil

Answer the following question given this paragraph: Blastocyst. The blastocyst consists of an outer layer of cells called the trophoblast and an inner cell mass called the embryoblast. The blastocyst fluid-filled cavity is also known as the blastocoel or blastocoele.
