6：The following appeared as part of a newspaper editorial.
“Two years ago Nova High School began to use interactive computer instruction in three academic subjects. The school dropout rate declined immediately, and last year’s graduates have reported some impressive achievements in college. In future budgets the school board should use a greater portion of the available funds to buy more computers, and all schools in the district should adopt interactive computer instruction throughout the curriculum.”

1， 没有排除他因。很可能是学校出台的policy要求老师上课认真，学生更加勤奋导致的。同时发生不能说明因果。stricter discipline applied last year.

7：The following editorial appeared in the Elm City paper.
“The construction last year of a shopping mall in downtown Oak City was a mistake. Since the mall has opened, a number of local businesses have closed, and the downtown area suffers from an acute parking shortage, and arrests for crime and vagrancy流浪 have increased in the nearby Oak City Park. Elm City should pay attention to the example of the Oak City mall and deny the application to build a shopping mall in Elm City.”
1， To begin with, the author fails to establish the causal relationship between the shopping mall's opening and the closing of local businesses.
2， Moreover, the author's conclusion is also based on the assumption that the shopping mall has caused the increase in crime and vagrancy.
Finally, even if the shopping mall did cause the closing of local business and the increasing crime and vagrancy in Oak City, the author's prediction that Elm City will suffer from the same fate as Oak City is still open to doubt.
