The correct answers:

1) tainted source is adulterated, biased and corrupted information that may eventually affect a study, trial, investigation.

2. Historical research is important because it can help students and teachers (masters, professors, educators) understanding with assurance the fact in a essay/ study/ investigation. The main purpose of historical research is preserving and interpreting facts correctly.

example of dubious secondary information: fake news, when there is divergent information about an official source of information. Often the source language is not appropriate, accurate, and unbiased.
