You should use both open and closed questions because you may get a shorter answer or a longer answer. It is better to use open question because you can get a more specific answer instead of a one word answer and is a better way to learn more about a person. It is better to use closed questions it is quicker and simpler because a closed question is a one/two word answer.
Example: Closed- What kind of pet do you have? Answer - Dog
Open- What type of pet do you have and where did it come from? Answer- I have a dog and it came from an animal shelter in Virginia.
You should use Google search tips because it is a better way to get more specific information or definitions quicker and easier. A good tip to use is the minus sign for example. This tip is good to use because if you put them minus sign in front of the word, it will eliminate anything popping up that has to do with that word.
Example: If you want to look up beer and not have the company British Beer pop up,, you could search “beer -British Beer Company”
