Question

in the past 10 years, public consumption of bottled water has grown a lot. a decade ago, very few people drank much bottled water. now, studies estimate that about 200 bottles of water per person are consumed every year. however, all that bottled water is causing a lot of problems. first of all, very few of the bottles are being recycled. about 60 million bottles of water are consumed daily. there just is not enough room for all that garbage. secondly, bottled water is actually less safe than tap water. government safety requirements are much stricter for tap water. a large percentage of bottled water comes straight from city water supplies, anyway! and, surprisingly, tap water often beats bottled water in taste tests.

1. this passage is mostly about

a. tap water.
b. bottled water.
c. recycling plastic.
d. garbage problems.

b. abraham lincoln is one of the most well - known presidents.
c. the black hills national forest is located in south dakota.

Explanation:

For question 20: The passage opens with the growth of bottled water consumption, then focuses on the problems caused by bottled water (low recycling rates, safety concerns, taste comparisons to tap water). All content centers on bottled water.
For question 21: If Mount Rushmore is a famous tourist monument, a supporting statement would link it to being a key tourist draw. The sentence stating it is the main attraction of the Black Hills (a tourist destination in South Dakota) directly supports that tourists visit it.

Answer:

1. B. bottled water.
2. A. Mount Rushmore is the main attraction of the Black Hills.
