Here is an example. Below, you can see a screenshot of a question from the experiment. This example has two charities.

The first line displays the total amount of tokens available to you. This always is equal to {{C.TOKEN}} tokens.

Then, the list of charities is presented. The first option always is "No, I will not donate on this occasion." You can use this option, and click on "Next" to move on to the next question.

The second and third options list two charities. You can select one charity and in the box below indicate the amount of tokens (out of 100) that you want to donate.
Then, click on "Next" to move on to the next question.
