Its not important to consider the source of information before deciding if it is credible true or false

Answer is false. You should always make sure you are using credible sources. Let's just say you are doing a paper on marine biology. You chose your source of information from an article written by a surfer. This in not credible since a surfer most likely doesn't know correct facts. Instead, you should include an article written by a marine biologist or an organization. This will have more facts.

True you should make sure you are getting your information from a reliable source for example this website would not be considered a reliable source
