What is hidden in 3D image?

One night Jack Evans, along with his 3 university friends went out drinkinig till late night, as many college students are prone to do, and didn't study for their test, which, of course, was scheduled for the next day.

In the morning they thought of a plan. They made themselves look as dirty and weird as they could with grease and dirt.

They went up to the dean and explained that they had gone out to a wedding last night and on their return the tire of their car burst. They continued to explain how they had to push the car all the way back and that they were in no condition to appear for the test.

The dean, being a compassionate human being said that they could take the test after 3 days. The students graciously replied that they'd be ready by that time.

On the third day, they appeared before the dean. The dean explained that since this was a special test all four were required to sit in separate classrooms for the duration of the exam.

They all agreed as they had prepared well in the last three days. The test consisted of 5 questions with total of 100 points:

MID SEMESTER COURSEWORK EXAMINATION
