Modern phones provide an efficient way for people to correspond with one another. However, text messaging can damage a high school student's ability to write effectively. A student who communicates in writing only through shorthand language in text messages could instead be writing complete words and sentences, and thus, will have less practice writing complete words and sentences than do other students.
Which of the following is an assumption made by the above argument?
A. Using shorthand language to communicate with friends does not enhance creative thinking in high school students.
B. High school writing classes have a minimal effect, if any, on a student's writing ability.
C. Uses of modern phones that do not involve writing (playing games, for instance) are not detrimental to writing ability.
D. Students often have access to devices other than phones, such as laptop computers, on which they could choose between using shorthand language and writing complete sentences.
E. Students who do not use shorthand language to message their friends spend at least some of their time writing in complete words and sentences.
