-Two break points are selected randomly (and distributed uniformly) on the stick.
The stick is first broken into two pieces. The longest (or rather, not the shortest) is then broken into two.
-The stick is first broken into two pieces. A piece randomly selected with probability 1/2 is then broken into two.

Answer:
the percent of increase is 24%
Step-by-step explanation:
The percent of increase in general could be calculate as:

where Vf is final value and Vi is initial value.
From the question we know that Vi is equal to 25 and Vf is equal to 31. Replacing this values on the equation we get:

That's mean that at second attempt the percent of increase is 24%, taking into account that at the first attempt a student get 25 questions correct.
