Polyvinyl chloride, or pvc, is used in most water-carrying pipes in the united states. known for their resistance to the corrosion that can be caused by water, pvc pipes are more durable than the metal pipes of old. as useful as pvc is, it may be surprising that it was accidentally discovered in 1835 by henri victor regnault, who observed a mysterious white solid plastic forming inside some test tubes that were left exposed to sunlight in his lab.
it can be inferred from the passage that metal pipes:

a. are used more than pvc pipes outside of the united states
b. are more expensive than pvc pipes
c. are more likely to corrode than pvc pipes
d. are no longer used in the united states

The answer is c because they are more likely to corrode than metel pipes

"everyday

use" was written by alice walker. this is a story about two sisters, dee

and maggie wanting to have the handmade quilt. maggie wants to use the thing

for its purpose, while dee appreciates it for being “her heritage”.   the quilt represents family heritage. it was

believed that only dedication and years of hard work can represent a  quilt. 

mama decided to give

the quilts to her less fortunate daughter, maggie because she believed that dee

could not hold the true meaning of their family heritage and   that she would not use the quilts for their

purpose. however, dee believed that maggie can’t appreciate the quilts just as

how she sees them, and she thought that the quilt will be put to “everyday use”

by maggie and within 5 years or so, the quilt will turn into a rag. in the story, dee strongly believed that maggie do not deserve the quilts.

explanation:

have a great day!
