Phung is analyzing poems by E. E. C*mmings. He is searching the Internet for some poems that are not in his literature textbook. He comes to a website called Famous Poets and Poems. Although the website has quite a few poems by C*mmings, the first thing he sees when the page loads is an advertisement. Then, three advertisements appear on the page before any other text. Is this a good source for Phung to use? Why or why not?
