Interacting with profiles

According to your answers to the previous task, we have prepared several fictitious profiles. The profile owners selected their profile picture and names by themselves. The interaction is simple: after you examine the profiles, you need to make a choice between the 2 profiles. You can indicate your choice by clicking on the button below the profile.

Below is an example interface. Notice that the "info" button that is circled red below can help you expand the details to the profiles, and view the profile picture. .
