Question: Answer the following question given this paragraph: An experiment generally tests how one variable is affected by another. The affected variable is called the dependent variable . In the plant experiment shown in the Figure above , the dependent variable is plant growth. The variable that affects the dependent variable is called the independent variable . In the plant experiment, the independent variable is fertilizersome plants will get fertilizer, others will not. In any experiment, other factors that might affect the dependent variable must be controlled. In the plant experiment, what factors do you think should be controlled? ( Hint: What other factors might affect plant growth?). Q: In a scientific experiment, the variable that is affected by the other one is called what? A:
OPTIONS:
- effective variable
- essential variable
- independent variable
- dependent variable
Answer: dependent variable

input with options: Answer the following question given this paragraph: Oceans are an important part of the water cycle. They absorb gases from the atmosphere. They evaporate and supply water vapor to the atmosphere. Q: Where do oceans absorb gases from? A:
OPTIONS:
- stratosphere
- wind
- sunlight
- atmosphere
output: atmosphere

Q: Answer the following question given this paragraph: While the great majority of the alpha particles did pass straight through the foil with no deflection, to everyone's surprise, some alpha particles were deflected. In fact, some alpha were bounced almost straight backward by the foil. Rutherford, using Coulomb's law and Newton's laws found that the results could be explained only if all the positive charge of the atom were concentrated in a tiny, central core, now called the nucleus . Rutherford's model of the atom is therefore, called the nuclear model of the atom. All of the positive charge and essentially all of the mass of the atom are in its nucleus. The atom is 10,000 times as large as the nucleus and is mostly empty space. It was known that electrons are outside the nucleus but how the electrons were arranged in an atom was still a mystery. Q: The nucleus is comprised primarily of? A:

OPTIONS:
- energy
- faith
- matter
- empty space

A: empty space

input: OPTIONS:
- solar light
- ultraviolet light
- thermal light
- infrared light Now, answer this question: Answer the following question given this paragraph: Infrared light is light with the longest wavelengths and lowest frequencies. You can't see infrared light, but you can feel it as heat. Besides the sun, flames and living things give off infrared light. Q: What type of light can you feel as heat but not see and has the longest wavelengths and lowest frequencies? A:
A:
output: infrared light

Answer the following question given this paragraph: Cells are the basic building blocks of life. They are like tiny factories where virtually all life processes take place. Some living things, like the bacteria in Figure above , consist of just one cell. They are called single-celled organisms. You can see other single-celled organisms in Figure 2.2. Some living things are composed of a few to many trillions of cells. They are called multicellular organisms. Your body is composed of trillions of cells. Q: What do we consider the basic building blocks of life? A:

OPTIONS:
- atoms
- neurons
- muscles
- cells

Answer: cells

Q: Answer the following question given this paragraph: Alloys can be one of two general types. In one type, called a substitutional alloy, the various atoms simply replace each other in the crystal structure. In another type, called an interstitial alloy, the smaller atoms such as carbon fit in between the larger atoms in the crystal packing arrangement. Q: Historically, malaria has rivaled what as the leading cause of human death by infectious disease? A:

OPTIONS:
- heart attack
- hepatitis
- cancer
- tuberculosis

A:
tuberculosis
