All the space in the lower part of the screen is preventing users from being able to see the whole screen including the Check button. This forces user to arrow down/scroll down for each and every question. That's unnecessary effort. There is room to eliminate 3-4 lines between the question and the Check button, which would be enough room to allow Check button to be visible without down arrow. It would also make the overall presentation tighter. And can probably accomplish it with eliminating just 2 lines.
