Eric is conducting research about the exploration of Antarctica, and he has gathered these resources:

• a diary written by someone who has traveled to Antarctica twice
• a brochure printed by a cruise ship advertising trips to Antarctica
• a government website listing regulations for exploring Antarctica
• an interview with a group interested in mining for gold in Antarctica

Which resource is likely to be most credible and why?

A diary written by someone who has traveled to Antarctica, because this person has actually visited Antarctica.
A brochure printed by a cruise ship that travels to Antarctica, because it is illegal for a company to print inaccurate information.
A government website listing regulations for exploring Antarctica, because governmental sources must provide accurate information.
An interview with a group interested in mining for gold in Antarctica, because its members feel strongly about what they want to do.
