ScaleItem

A question item that allows the respondent to choose one option from a numbered sequence of radio buttons. Items can be accessed or created from a Form. When used in a quiz, these items are graded.

 // Open a form by ID and add a new scale item.
 var form = FormApp.openById('1234567890abcdefghijklmnopqrstuvwxyz');
 var item = form.addScaleItem();
 item.setTitle('Pick a number between 1 and 10')
     .setBounds(1, 10);
