Q: Silk and cotton are examples of what type of fibers? Read this paragraph and choose the correct option from the provided answers: Many of the fibers that compose the materials for our clothes are naturally occurring. Silk and cotton are examples of natural fibers. Silk is produced by the silkworm, and cotton is grown as a plant. However, several chemical processes are used to treat silk thread so that it is shrink-resistant and will repel water. Chemical dyes are frequently used to color various fabrics. Cleaning requires special soaps or chemicals used to dry-clean materials. Cotton will grow better if the boll weevil (an insect that kills the plant) is eliminated with the use of specific insecticides. Ironing of cotton is made easier by the use of chemicals that produce a permanent press in the material. Choices: - mechanical - artificial - coral - natural A:
natural

Q: In which direction does water travel? Read this paragraph and choose the correct option from the provided answers: After a heavy rain, you may find puddles of water standing in low spots.

A lake is a large body of standing water. Most lakes have freshwater, but a few are salty. The Great Salt Lake in Utah is an example of a saltwater lake. Choices: - backwards - northwest - uphill - downhill A:
