The closest to being a free good of the one given would be: (i) a scholarship for a brilliant but impoverished student. (ii) Free “meals on wheels” programs for the aged and infirm, (iii) a winning lottery ticket you determined on the sidewalk, (iv) Hugs from a friend you hadn’t seen within weeks and (v) A surprising warm front blowing from your town on a cold winter day.
Please help me to solve the problem of scarcity that is given above.
