What was the major difficulty with trade in ancient greece?

Mountain ranges made transportation very difficult is the correct answer.

Explanation:

Geography and trade affected the development of Greece in positive and negative ways. Its geography is mountainous and it is surrounded by the sea on three sides. The mountains cover up to eighty percent of Ancient Greece. They were difficult for overland transportation and didn't provide them with grain, timber, animal hides, slaves , nuts, cheeses, figs and flax. Greece lacked farmland resources and they had to rely on trade for getting the materials and the resources which they needed. They used to get grain, olive oil, wine, pottery and woolen textiles from the Minoans.

Due to the mountains land the city states became more independent and had less communication with each other. Different city states used to trade with each other.
