Answer to Question 1

Answer: D
Explanation: D) A Boolean search lets you define a query with greater precision, using such operators as AND (the search must include two terms linked by AND), OR (it can include either or both words), or NOT (the search ignores items with whatever word comes after NOT).

Answer to Question 2

Answer: B
Explanation: B) One of the most powerful aspects of online research is the ability to automatically monitor selected sources for new information. The possibilities include subscribing to newsfeeds from blogs, following people on Twitter and other microblogs, setting up alerts on search engines and online databases, and using specialized monitors such as TweetBeep and TweetDeck to track tweets that mention specific companies or other terms.
