IDevice Question Icon Activity: Paraphrasing
Look at the following paragraph from B. Wuethrich's article "Chasing the Fickle Swine Flu" in Science, 2003, vol 299, issue 5612, page 1502:

As they seek to understand what upset the status quo in North American swine, researchers have turned to the environment. For North American pigs, the environment has recently changed dramatically in two ways: herd size and vaccination practices.

Which of the following would be the best way to paraphrase?

  
1. Researchers have found that “herd size and vaccination practices” are two recent changes in the environment that could account for the origins of swine flu in North America. (Wuethrich 1502)
2. Researchers are seeking to understand what upset the status quo in North American swine. They think it might be the environment. Herd size and vaccination practices are two recent dramatic changes.
3. Wuethrich reports that “to understand what upset the status quo in North American swine, researchers have turned to the environment.” For North American pigs, “the environment has recently changed dramatically in two ways: herd size and vaccination practices.” (Wuethrich 1502)
