- (B) "so are smartphones unfortunately, they are the cell phones which permit" is confusing with "which permit," as the sentence would sound better with "that permit."
- (C) "also unfortunately smartphones, they are the cell phones that permit" feels clunky and does not effectively introduce the contrast between computers and smartphones.

If \(8x + 5x + 2x + 4x = 114\), then, \(5x + 3 = ?\)
If \(r = 5 z\) then \(15 z = 3 y,\) then \(r =\)
