– Its is somewhat unreliable


By looking at the date that the article was published, we can see how recent and up to date an article is. This gives a sense to the readers  when the statistics shown were based on, and how long ago the article was posted. The most recent articles would be more reliable than the other articles. Relevance refers to the usefulness of the information. Reading an article that are very complicated with an adult level of vocabulary can cause more confusion to teenagers. Having biased tone can only have the readers know about one side of a situation. By looking at the relevance, it is easy to find an article that matches my reading level and purpose. Authority refers to the source of information. Knowing where the information comes from and who it is published by can help determine the reliability of the information. It would not be reliable if it is not written by an expert of a subject. The purpose refers  to the reason of existence of the information. If it is there to persuade someone or for a use of propaganda, then it would probably be biased, making the source unreliable. Even though the source above is published by a reliable source, it is written about seven years ago, and it does not fit my reading level, which makes the source somewhat unreliable.
