Once you add in the eligibility question, you'll then select the response(s) that makes an employee eligible for the plan.
In this case, we selected "Full time". When employees go through ALEX if they select they are Full-time, then they will see this plan. If an employee states they're "Part-time" or "Something else", they will not see this plan.
This logic holds true for all plans that have an eligibility question and answer(s) selections.
