After several years of slow economic growth, world demand for petroleum began to rise rapidly in the 1990s. Much of the increase in demand was met by additional supplies from sources outside OPEC. OPEC during this time was unable to restrain output among members in its effort to lift oil prices. What best describes these events?
The rise in demand shifted the demand for oil to the right. As price rose, quantity of oil supplied rose.
European Union subsidizes its farmers. How do these subsidies make it difficult for farmers in developing economies to compete in the world farm market?
The subsidies shift the supply of EU farm goods to the right, lowering world prices of farm goods and the price developing country farmers can receive for their produce.
