Let me help you understand this. You just type whatever one you want, like if I wanted number one, I would type "Do a barrel roll feeling lucky". Or for number two you would type "Google sphere feeling lucky". Get it? Now try it!
Google Scholar is awesome. Note: if you get articles that are "pay for" go back to the Rasmussen Library homepage and use Discovery to search for the article title. We might own it in our databases. You won't have to pay.
