Answer the following question given this paragraph: When the wind drops fine particles of silt and clay, it forms deposits called loess ( Figure below ). Loess deposits form vertical cliffs. Loess can become a thick, rich soil. That's why loess deposits are used for farming in many parts of the world. Q: What do loess deposits form? A:

OPTIONS:
- rotational cliffs
- horizontal cliffs
- diagonal cliffs
- vertical cliffs

Answer: vertical cliffs

Problem: OPTIONS:
- twig
- stamen
- root
- stem
Q: Answer the following question given this paragraph: Stems are organs that hold plants upright. They allow plants to get the sunlight and air they need. Stems also bear leaves, flowers, cones, and smaller stems. These structures grow at points called nodes. The stem between nodes is called an internode. (See Figure below . ). Q: What is the basic structure that holds plants upright, allowing plants to get the sunlight and air they need? A:
Answer: stem

Problem:OPTIONS:
- negative change
- positive change
- atmospheric change
- physical change

Answer the following question given this paragraph: A physical change is a change in one or more physical properties of matter without any change in chemical properties. In other words, matter doesn't change into a different substance in a physical change. Examples of physical change include changes in the size or shape of matter. Changes of statefor example, from solid to liquid or from liquid to gasare also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting. Four examples of physical change are pictured in the Figure below .

Q: A change in one or more physical properties of matter without any change in chemical properties is called what? A:
****
A: physical change

Answer the following question given this paragraph: The first continents were small but they grew over time. Supercontinents have formed at least five times in Earth history. Q: Supercontinents have formed at least how many times in earth history? A:
OPTIONS:
- twenty
- nine
- two

Answer the following question given this paragraph: Ionic bonding typically occurs when it is easy for one atom to lose one or more electrons and another atom to gain one or more electrons. However, some atoms won't give up or gain electrons easily. Yet they still participate in compound formation. How? There is another mechanism for obtaining a complete valence shell: sharing electrons. When electrons are shared between two atoms, they make a bond called a covalent bond. Let us illustrate a covalent bond by using H atoms, with the understanding that H atoms need only two electrons to fill the 1s subshell. Each H atom starts with a single electron in its valence shell:. Q: When electrons are shared between two atoms, they make a bond called a what? A:
OPTIONS:
- metallic bond
- ionic bond
- hydrogen bond
- covalent bond

Answer: covalent bond

input with options: Answer the following question given this paragraph: This is a constellation, a pattern of stars in the night sky. This constellation is called Orion. The features you can see best are his belt and sword. You can see Orion's belt in the sky from many locations. These stars are very bright. For many constellations, the stars are not near each other. They just happen to appear near each other in our sky. Q: What do you call a pattern of stars in the night sky? A:
OPTIONS:
- Solar Systems
- planets
- cluster
