Q: Answer the following question given this paragraph: The fluffy white fibers on this plant look like cotton balls because that's what they are. The plant is a cotton plant, and the fibers are used to make cotton fabric. Cotton fibers consist of one of the most common compounds on Earth: cellulose. Cellulose is a biochemical compound found in all plants. It belongs to the class of biochemical compounds called carbohydrates. Q: What is one of the most common biochemical compounds on earth and is found in all plants? A:

OPTIONS:
- carbon dioxide
- hydrogen
- sulfur
- cellulose

A: cellulose

input: OPTIONS:
- premium force
- drop force
- optimal force
- output force Now, answer this question: Answer the following question given this paragraph: When you use a machine, you apply force to the machine. This force is called the input force. The machine, in turn, applies force to an object. This force is called the output force. The output force may or may not be the same as the input force. The force you apply to the machine is applied over a given distance, called the input distance. The force applied by the machine to the object is also applied over a distance, called the output distance. The output distance may or may not be the same as the input distance. Q: What do you call the force a machine applies to an object? A:
A:
output: output force

Answer the following question given this paragraph: Between 1971 and 1982, the Soviets put a total of seven Salyut space stations into orbit. Figure below shows the last of these, Salyut 7. These were all temporary stations. They were launched and later inhabited by a human crew. Three of the Salyut stations were used for secret military purposes. The others were used to study the problems of living in space. Cosmonauts aboard the stations performed a variety of experiments in astronomy, biology, and Earth science. Salyut 6 and Salyut 7 each had two docking ports. One crew could dock a spacecraft to one end. A replacement crew could dock to the other end. Q: What country put seven salyut space stations into orbit between 1971 and 1982? A:

OPTIONS:
- United States
- China
- Japan
- soviet union

Answer: soviet union

Problem: OPTIONS:
- convex
- circular
- curved

The image may be real, upside down, and reduced in size; or it may be virtual, right-side up, and enlarged. Q: What do you call a mirror shaped like the inside of a bowl? A:
Answer: concave

Problem:OPTIONS:
- geological age
- chemical age
- full age
- absolute age

Answer the following question given this paragraph: The age of a rock in years is its absolute age . Absolute ages are much different from relative ages. The way of determining them is different, too. Absolute ages are determined by radiometric methods, such as carbon-14 dating. These methods depend on radioactive decay. Q: The age of a rock in years is its? A:
****
A: absolute age
