You will be asked to evaluate {{C.num_relevant}} pairs of options. Consider the example below. The pair of options to be evaluated is on the left. Compare this pair of options to each fixed amount shown in the table on the right. For each row, decide whether you prefer the fixed amount or the pair of options. There will be two steps to this procedure. First, you make a coarse selection, then click Validate first selection. A finer list will appear to let you refine your answer.

The payment rule is designed in a way such that it is optimal for you to select in each row the alternative (i.e., fixed amount or the pair of options) that you truly prefer. The computer has randomly chosen a fixed amount between {{C.coarse_lower_bound}} and {{C.coarse_upper_bound}}.

• If you preferred the pair of options over the chosen fixed amount, you will be asked to choose one option from the pair of options. Your bonus payment will then be determined by this option as we explained above.
• If you preferred the chosen fixed amount over the pair of options, you will receive the fixed amount as a bonus payment.

Try it out: To make sure you are comfortable with the procedure, please complete the example task below as follows:

• If the fixed amount is lower than {{C.target_value}}, you prefer the pair of options.
• If the fixed amount is higher than {{C.target_value}}, you prefer the fixed amount.
