6. Textual Support for Interpretation
Read the following student essay. Then answer the questions that follow it.
 Not all thieves lurk in dark alleys and parks. Some sit with their faces lit by the glow of their computer monitors, copying, pasting, and printing.
 It may seem like just another helpful source of information, but the Internet has taken the theft of “intellectual property” to a new level. Part of the problem is that most students don’t really know the exact definition of plagiarism or its consequences. Some say that using someone else’s ideas without attributing them is a form of theft, but most people don’t think of it as a serious crime.
 For teachers, Internet plagiarism has been especially problematic compared to “theft” from other sources. This is because it is so easy to copy and paste from the Internet. To counter student plagiarism, services designed to detect copied material have emerged to aid teachers. One company, TurnItIn.com, has developed a system for detecting material plagiarized from the Internet. Teachers can upload student works onto the site, which searches for similarities to material from all over the Web. The teachers receive an “originality report” within a few days.
 “The threat of using [these programs] will stop a lot of students. They will be afraid they’ll be caught. Unfortunately, fear is what works,” English teacher Judy Grear said.
 A main concern is not only the use of a few plagiarized sentences, but of entire papers. “Paper mills” like SchoolSucks.com and Evil House of Cheat are some of the most popular sources for pirated papers.
 In addition to such blatant “cut and paste” plagiarism, most teachers agree that students must be wary of the theft of ideas. One plagiarism-detection program, Word Check, asserts through their Web site, “Whether you agree or disagree on how information should be used or reused in digital form, one thing is clear: protecting intellectual property from theft and infringement is the number one security issue.”
 By some definitions, it seems like everyone plagiarizes. But for many students who feel that they might unknowingly plagiarize, programs like TurnItIn.com are intimidating. The detection system on TurnItIn.com, which is a part of plagiarism.org, claims to detect plagiarism down to the eight-word level, which many fear could include accidental lifting of words.
 The thieves are out there, and they aren’t wearing stocking caps. They’re not robbing banks; they’re stealing words.

Where is the best location to add this quotation? “I think that the idea is good,” Chris M., a senior, said. “But it might be a little extreme because some phrases are common enough that they might be in more than one essay.”
