Only cell phone towers equipped with LTE radios can transmit data at speeds high enough so that users can watch a movie without downloading the entire movie first. To be able to stream movies however, the user must have an LTE equipped cell phone. While most people had LTE equipped cell phones in Arizona two years ago, the number of cell phone towers with LTE has quadrupled during this time. Since there has been no significant addition in the number of LTE cell phones and the new towers have not increased coverage, the number of people in Arizona streaming movies has not changed in the last two years.
Which of the following is an assumption on which the argument depends?
A.Few, if any, LTE towers that have been added in the last two years ago broadcast to people who were not covered earlier.
B.The number of people who download movies first on their phones and then play them has not increased in the last two years.
C.No user who was unable to stream movies two years ago is able to do so today because of the capacity added by the new towers.
D.The users who did not have LTE two years ago were not able to receive any service from LTE equipped cell phone towers.
E. No user who did not have a LTE cell phone two years ago owns one now.
Official explanation will be posted at a later stage.
