Answer:
Timothy; John
Explanation:
A country has a absolute advantage in producing a commodity if it produces that commodity with less inputs than the other country.
For Timothy, he can produce:
2 pairs of shoes per hour or 4 units of clothes per hour
For John, he produces:
1 pair of shoes per hour, or 5 units of clothes per hour.
