Grace was telling her friend Alexander about an idea she had for a new app. Alexander took this class, so he encouraged Grace to create a prototype of her idea. Grace, who did not take our class, then felt super sad and disappointed: she doesn't know the first thing about coding. Alexander, always a nice guy, told her not to worry because....

Question $9$ options:

Physical prototypes aren't that important; Grace could just talk about her idea without showing it

Prototypes aren't necessary for apps

Grace could learn coding for a few years and then develop her prototype

People probably already know what she's thinking anyway, so a prototype isn't really required

Grace could draw a simple sketch mock$-$up with pencil and paper
