I'm totally okay with clicking Next button. But if you really insist, then do what @yreg says, but include big, BIG back button at the top. Bonus points if you can make it look like stacked papers on the desktop: ───┬───┬───────────────┐ │ │ │ 1 │ 2 │ <- │ │ │ │ │ │ A. Lorem ... │ │ │ │ │ │ B. Ipsum ... │ │ │ │ │ │ │ │ │ │ ───┴───┴───────────────┘ For the mobile in the portrait mode this is not the best option, but still could work if using vertical stack of cards layout: ┌─────────────┐ │ 1 │ ├─────────────┤ │ 2 │ ├─────────────┤ │ <- │ │ │ │ A. Lorem ...│ │ │ │ B. Ipsum ...│ │ │ │ │ │ │ │ │ │ │ └─────────────┘ NB Next button should be present always, even if it would be meaningless because you would advance on a single-choice question automatically. Thing is, sometimes things break and then someone would need to press the Next button. Also you can use colour coding for multiple-choice questions by highlighting the Next button if anything selected, confirming for the user what they can advance. And no, grey on white is the worst possible colour scheme ever.
