The correct answer is to tell the interviewer that this is terrible coding and that you would never create a public variable in the Main.prg.
You would create an app class, and build properties on it, then reference those properties.
If a company is asking this kind of question, I'd go work somewhere else.
Just my humble opinion.

Everything makes sense in someone's mind
public class SystemCrasher :ICrashable
In addition, an integer field is not for irrational people
