5. In the United States where land is cheap, the ratio of land to labor used in cattle raising is higher than that of land used in wheat growing. But in more crowded countries, where land is expensive and labor is cheap, it is common to raise cows by using less land and more labor than Americans use to grow wheat. Can we still say that raising cattle is land-intensive compared with farming wheat? Why or why not?

6. Is the following statement true or false? Discuss based on the HeckscherOhlin trade model: "The world's poorest countries cannot find anything to export. There is no resource that is abundantcertainly not capital or land, and in small poor nations not even labor is abundant."
