Read the paragraph.(1) beekeepers began reporting devastating bee losses beginning in 2006—sometimes as much as 90 percent of their hives! (2) most of the bees were gone. (3) this phenomenon is called colony collapse disorder, or ccd. (4) scientists remain unsure of what causes ccd, but they know that it has happened before. (5) reports of disappearing bees date from the 1800s. which revision would make the paragraph more precise?
a. sentence 2: change “were gone” to “had simply vanished.”
b. sentence 3: change “phenomenon” to “thing.”
c. sentence 4: change “remain” to “continue to be.”
d. sentence 5: change “date from” to “come from as far back as.”

A. Sentence 2: Change "were gone" to "had simply vanished"

Explanation:

By changing the sentence (2) "Most of the bees were gone" into "Most of the bees had simply vanished", we will get a more definite reason for the disappearance of the bees. Using "had gone" is just not too much emphasis on the occurrence and the gravity of the situation, while "had simply vanished' would have more stronger sentence hold on the reader.

many were disgusted, nauseated and shook their heads with disapproval upon finding out about the recycling of water process. however, they do not seem to understand that this process actually saves water.

although individuals may argue that it is unhealthy, and or unsafe to drink water that is "from toilet to tap" , the water is 100% safe to drink and involves forcing the water across a membrane, which "removes   any impurities, including viruses, pharmaceuticals and dissolved minerals" , according to paul rozin, a psychology professor who studies revulsion.

i agree that that the thought of drinking water that once ran through someones kitchen sink isn't quite appealing, but recycled wastewater is safe to drink. it also saves water. "the city produces nine million gallons a day" claims russell schreiber, the city’s director of public works.

recycled waste water has absolutely no health concerns whatsoever. when wastewater goes into a system, it's absorbed back into the ground. thus, it goes into a sewer system, then goes through a treatment process that removes contaminants before being released. nonetheless, there is no problem in drinking water that has been recycled.

"in drought-ed california, there are six state agencies that use wastewater that comes from an intellectual property source," according to the university of california, riverside. studies show that this water is completely safe to drink, however, it still doesn't mean people are going to happily pour it in a water glass.

researchers hope it "may make consumers more amenable to drinking recycled wastewater," extraordinarily, women who have a higher "disgust reaction" and make most consumer purchasing decisions.
