You should use both open and closed questions because you can have either a very complex answer, or a short, simple answer. When asking a closed question, such as “what is your favorite color?” you can give a short, sometimes one word answer. This type of question doesn’t usually require a lot of thought. On the other hand, when asking an open question, such as “what is the meaning of life?” requires a lot more contemplation, thus a longer and more complex answer.

You should use Google search tips because it helps to have a more efficient, and specific search. You can narrow down your search and look up specific words by using double quotations “”. By using this you’re searching sites with only the words in the quotes. For example: “Blueberry pie.” This allows you to search pages with both blueberry, and pie in them. Another tip that makes Google search more efficient is the minus symbol -. This allows you to cancel out a word in your search. For example: Candy recipes-chocolate. This means that the sites that come up will have candy recipes that don’t have chocolate in them.
