This question already has an answer here:
How exactly should we handle these? I mean the questions are somewhat different, they are not exactly "duplicates" but the answers of those two are basically identical or at least similar. Would it be okay to edit one of both questions to make things more clear?
The user of the question said that he didn't know about the dupe, which i can fully understand since the older question really sounds a bit more specific while the newer one faces the broader (more clear) problem.
What exactly can we do to prevent duplicate answers?
