    <p>It is important that you fully understand the task and consequences of your choices. Therefore, we will now ask you a few questions about the task with the help of an example scenario.</p>

    <h4>Example scenario</h4>
    <p>Individual A is at a local coffee shop near campus. While there, Individual A notices that someone has left a wallet at one of the tables. Individual A must decide what to do. Individual A has four possible choices:</p>
    <ul>
        <li>take the wallet</li>
        <li>ask others nearby if the wallet belongs to them</li>
        <li>leave the wallet where it is</li>
        <li>give the wallet to the shop manager</li>
    </ul>
    <p>Individual A can choose only one of these four options. The table below presents a list of the possible choices available to Individual A. For each of the choices, you would need to indicate whether you believe choosing that option would be very socially inappropriate, somewhat socially inappropriate, somewhat socially appropriate, or very socially appropriate. Imagine you have made the following choices:</p>

    <div style="text-align:center; margin:20px 0;">
