At the start you just let it speak and then you will go to the first question, for the first question click the one you would rather do and then after you do that it will show the percentage of the which ones people most chose and the one the people least chose. In the second/last question you choose one in your head after looking at the options and then press space to see the percentages. At the end the 'Thankyou' screen talks a bit so don't tab out of the right away.
