How do you know which answer is correct when there are more than one posted to a specific question?

Often, you will see answers from diverse contributors that simply complement each other. If diverse answers seem to be different or even opposing, those are not absolute answers but just diverse existing views. Do not get confused by this, just read the diverse views and make your own assessment, check also if there are any links that could help you. If you are still in doubt, make a new question with more specific wording.
