A form/branch of government independent from the law.
The correct answer is: "a handbook of government statistics
".
Government statistics are collected using objective measurament techniques and published by an official source.
The other three sources are not official, and probably, not objective as well. On the first hand, the information contained in a press realease from a company or in a claim in a political commercial, is subjected to the profit-maximization interests of a private company. On the other hand, a blog entry is very likely biased by the subjective opinion of its author.
This research indicated that <span>ordinary citizens are ill-informed about political issues, ill-equipped to understand politics, and quite fickle in how they stand on issues.
The majority of people tend to believe everything the press told them while ignoring the facts that all of the news outlets tend to have biased political leanings in their reporting.</span>
