A 4-column table has 2 rows. The first column is labeled country with entries Country A, Country B. The second column is labeled Cost (units) with entries 1, 1. The third column is labeled Petroleum (units) with entries 16, 8. The fourth column is labeled Seafood (units) with entries 8, 8. Without specializing, the total output for both countries after two days would be 48. If Country A were to specialize in petroleum, its output would be after two days. If Country B were to specialize in seafood, its output would be after two days
