Read the following excerpt from an argumentative essay.
Critics might say that smart phones in the classroom cause too many distractions. A 2009 article in Education Magazine made just such a claim. Although cell phones can certainly cause distractions, current research suggests that teachers and students are putting phones to better use. A 2013 Educator Insider poll reveals that 67% of high school instructors now encourage students to use phones in the classroom setting. Students without phones are actually at a disadvantage in the classroom. The poll lists Internet access, spell checks, and collaboration as three key uses of smart phones in an educational setting.

a. Cell phones should be allowed in the classroom.
b. Cell phones in the classroom cause too many distractions.
