What is taken before you can get it?

“A test”

While tests are often taken before you receive results, they are not typically something you 'get' in a tangible sense like a picture.

“A photo”

This is too similar to the correct answer, but it is incorrect because a photo itself is not taken; it is the action of taking the picture that precedes having it.

“A ticket”

Tickets are purchased or acquired, but they are not taken in the same way that a picture is taken before you can see it.
