Answer:
C) to fall
Explanation:
The relative price of beef will fall since Argentina can produce 1 ton of beef at the same price of 10 boxes of tulips,while Venezuela can produce 1 ton of beef at the same price of 15 tons of tulips. So Venezuelan beef is 5 boxes of tulips more expensive than Argentina's. When they start to trade, Argentina will be able to sell beef to Venezuela at a cheaper price until the price of Venezuelan beef lowers to match the Argentinean price.
