In the following, note that:
 * Q02 only shows the set of products checked in Q01 (by using array_filter)
 * Q02 also shows "Another product", the text entered into the "Other electronic" field in Q01
 * Q04 only shows products from Q02 that were checked (so the array filter cascades)
 * Q05 only shows products from Q02 that were not checked in Q02 (using a cascaded array_filter_exclude)
