Mock 26: improved formulation of the question

[rhoadesre]

Original question:
"Which TWO statements about the principle „Don’t repeat yourself” (DRY) are correct? (In other words: What could happen, if parts of the source code or configuration do exist in multiple copies in the system?)"

Problems:

1. the English can be improved
2. DRY states that you shouldn't repeat yourself, but the question asks, "what happens if you repeat yourself?"

Recommended question:
"Which TWO statements about the principle „Don’t repeat yourself” (DRY) are correct?
In other words: It should be avoided, that multiple copies of the source code or configuration exist within the system."

I guess the "parts of source code" might be a bit clearer in the explanation.

Maybe like this:

"Which TWO statements about the principle „Don’t repeat yourself” (DRY) are correct?
In other words: It should be avoided, that parts of source code or configuration are repeated within the system."

Not sure if "repeat" needs to be paraphrased, it seems to be a fairly common English word.
Alternatively: "[...] parts of source code or configuration are duplicated within the system."
