Unit 4: Types of Information

Good Evening!
Here are the sources which I would utilize for the following research questions.

Practice Questions:
1) Is a vegetarian diet healthier than a meat-based diet?  I would use scholarly or academic journals to address this topic.  Because, it is a topic where research has already been done, I will want to utilize the journals to find out what research has taken place and what results have been discovered.
2) Target often forces musicians to alter lyrics in order to have their CDs sold in Target stores. Is this censorship? I would use a subject encyclopedia to address this question.  I will want to get background information on censorship.  Because this is also a popular topic, I may want to look at magazines.
3) How much more can a college graduate expect to earn over someone with a high school diploma? This is a statistical question.  I will want to use reference books, statistical web sites, scholarly journals or books.  Obviously statistical web sites will offer some information.  Reference books and scholarly journals will offer in depth information.
4) Should educators use commercial services to combat plagiarism? I would use a scholarly or academic journal to address this topic.  Because research has already been done, I will utilize journals to find out what how effective the use of commercial services on plagiarism has been. 
5) Is the current lack of sunspot activity affecting global warming?  Again, I would want to use a scholarly or academic journal.  Thus I would use the in depth information presented.  I could also use a book as it would allow me to view in depth information on the topic.

My questions:
1) What is the history of censorship?  I would want to use a book or e book for this question.  This would allow me to get in depth information and a historical perspective on the topic of censorship.
2) What types of censorship are there? I would want to use a subject encyclopedia to get thorough background information on this topic.
3) How do various countries participate in censorship?  I will use a subject encyclopedia to get background information and then utilize books to get in depth information as well historical information.
