The reasons for why questions were down-voted, and why they were closed are hardly related. They don't trigger each other.
However, there might a several reasons explaining the correlation between the down-votes a question may get, and why it may get closed.
A question may be close-voted for several reasons:
- What's being asked is unclear, broad, or totally confusing. This can be sometimes helped by editing, but not all questions can be salvaged this way.
A question is not close-voted just because of the bad quality. There's no such criteria for close votes. However, if the question is still unclear after editing, then it may get closed as it's "not a real question" (nobody could still understand what was being asked).
The question does not contain enough information (For example "My PC has crashed. What now?"). You may ask the OP to add some more information, but if he/she fails to provide that, then there's a little chance that the question can be useful for the community, and it may very well then be closed due to being "too localized".
The question is clearly off-topic. The OP has not gone through the site FAQ.
I would down vote:
Q1: for not "taking responsibility for the question asked". You cannot expect people to help you when the questions are missing some structure, punctuation, or paragraph breaks.
Q2: because not everybody can read other people's minds (some cannot read their own minds, neither, but that's another topic!).
Q3: because every site on the internet has some kind of etiquette for participation. Why not check out the SU FAQ first?
