Long ago, only natural fibers such as cotton and wool were available to make cloth. In the 20th century, synthetic fibers such as polyester were invented. What is one way that synthetic fibers have changed society?
They are engineered by humans so they are better materials for all applications.
They are harder to make so they have limited the variety of products being sold.
They are less expensive than natural fibers so they make products more available.
They are available in unlimited amounts without depleting natural resources.

Cement is made by heating natural limestone in a kiln and then grinding the product to a powder. Cement is an ingredient used in making concrete. Concrete is made by combining water, powdered cement, and either sand or gravel. After the ingredients are mixed, the concrete releases heat and changes from a thick flowing mixture to a hard solid. Based on this information which statement correctly describes concrete?
Concrete is a synthetic material because the cement is made from limestone.
Concrete is not a synthetic material because the reaction occurs by itself once the ingredients are mixed.
Concrete is a synthetic material formed by a chemical reaction after the ingredients are mixed.
Concrete is not a synthetic material because all of its components come from natural resources.

What is one reason that a builder would use a synthetic material, such as concrete, instead of quarried stone in the construction of a building?
Concrete is more expensive than stone, so it is more desirable.
Concrete weighs more than the same amount of stone, so it is stronger.
Concrete is a synthetic material, so its use does not deplete natural resources.
Concrete can be readily poured into a desired shape, so it is easier to work with.

Carbon fiber composites are synthetic materials that are made by combining carbon fibers with a hardened resin. These materials are very strong and easily formed into specific shapes. Which of these considerations makes carbon fiber composites particularly useful as construction materials for parts used in certain types of airplanes?
They are more expensive than many alternative materials.
They weigh much less than other materials of the same strength.
They are synthetic materials built in manufacturing facilities.
They can be manufactured in many colors by adding dyes to the resin.

Synthetic fibers, such as nylon and rayon, have replaced a natural fiber, silk, for many uses. Which of these is most likely one of the reasons for this replacement?
Natural fibers make a cloth that cannot be cut into shapes as easily as synthetic fibers.
Natural fibers have more limited availability than synthetic fibers.
Synthetic fibers do not require using natural resources.
Synthetic fibers can be woven into cloth at a faster rate.
