How can the topic "students and cell phones” be presented as an argument?

a) recent surveys suggest that over 70 percent of all american students ages 14–17 own a cell phone.
b) students at omega high school have expressed interest in having access to their phones during school hours.
c) school policies regarding cell-phone usage varies by region and is the source of considerable debate.
d) cell-phone usage should be embraced at public schools as a means of information acquisition.

D) Cell-phone usage should be embraced at public schools as a means of information acquisition.

The words "should be" in option D show it to be a statement of opinion. The sentence sets up the claim that cell-phones should be embraced at schools. Option A is wrong because it is a statistic. A statistic cannot be argued. Option B is also a statement of fact. It says that the students "have expressed interest". This cannot be argued since the students either did or did not express interest - in this case, they did. Option C is also not correct because it is a true statement as well. There is no opinion.
