Usage of sources

throughout high school teachers strongly emphasized the importance of having a wide variety of sources. often times they would have a requirement of a certain number of sources just so you can learn to get several views about the same subject. also we were told countless times about the importance of giving credit where credit is due. citing sources is an absolute staple when writing any type of paper that involves research and in high school if we neglected to cite our sources we either got zeros or even suspended. all in all its been taught that you just need a good amount of sources and to give credit to those sources.
