How have search engines like google, bing, and yahoo! revolutionized the ability to do research? a. they are more difficult to access than the library b. they provide only information from reliable sources c. they provide immediate access to information on the web d. they take longer than using a card catalog but provide only expert sources

"C. They provide immediate access to information on the web" This is because you can get an immediate result as to what you are looking for rather than having to go all the way to a library or other place for resources. 

Hope this helps!
