Challenge: Responsive Web Design Projects - Build a Survey Form

Link to the challenge:

a radio button “group” is characterized by the radio buttons all sharing the same name attribute value.
This tells the browser that the user is only allowed to choose one of the radio buttons in that group.
Say you have a true/false question. You would present 2 radio buttons labelled true and false respectively.
You want the user to click only one of these at a time (they both cannot be selected).
So you set their name to be a value that is identical in both input elements.
