Question 5. Christina has a piece of transparent paper with some lines marked on it. She folds it along the dashed line.  What can she now see?  Let's take a look at our transparent paper and  recognize that when we flip it along the line in the middle, they will be in a flipped position.  So if we move the first line segment down, it would look like so. Then we move the second line segment down like so,  showing us that our first number will be 5.  If we continue doing this for all of our line segments, we end up with the numbers 5, 6, 9.  That is indeed the solution, which will be C.
