Bose released Wireless headphones – QC35 as a successor to their vastly popular QC25 wired headphones. While Bose claims that QC35 uses the same frame and technology as QC25 does, the average QC35 owner replaces the earcups every 12 months, twice as frequently as QC25 owner does. Since Bose did not increase the price of QC35 despite adding wireless capability, it must have reduced the quality of ear-cups in QC35 to make up for additional cost.
Which of the following, if true, most seriously weakens the author’s argument?
(A) Very few of Bose’s customers periodically clean their ear-cups, actions which can increase their life drastically.
(B) Since QC35 is wireless, it can also be worn while sleeping to reduce ambient noise.
(C) Most ear-cups tear apart when the headphones are stored in a backpack with a sharp object such as a scissor.
(D) While most QC25s are shared devices, most QC35s are used exclusively as personal devices.
(E) Bose charges a lower price for replacement ear-cups of QC35 than it does for QC25.
