There has been some discussion over the issue of questions being flagged as duplicate. There was a issue been brought up.

Question should not be flagged duplicate if answers can't be merged.

As an extension to the above question, I have following questions.

Do we flag duplicate questions or duplicate answers?

Lets consider two imaginary questions

• How to install chrome from .deb file?

• How to install firefox from .deb file?

Both the above questions have same answers sudo dpkg -i filename.deb.

Now should these questions be flagged duplicate?(question is different, answer is same)

What should be done when the flagger is not sure about OP's problem?

Say I find a question with body "I am getting dependency issue, this-this is the error message".

Should I first try to understand the problem of OP or just flag it with the master question and leave it to OP so that he/she should prove why it isn't duplicate.

Is it necessary that questions flagged dup be merged?

Can they just remainas they are, owning there own answers proudly and one would point to other?(I'm well aware that non users are automatically diverted to master question)

What when a user posts same question twice?

Sometimes a user may post same question twice. Assuming that first question is unanswered, what do you do in such cases?

There were some more question, but I don't remember the others. These are all for now.
