I want to know the answer to the following question:
What type of materials is Iran a leading manufacturer of in the Middle East?
All the background I'm provided with is that "According to FAO, Iran has been a top five producer of the following agricultural products in the world in 2012: apricots, cherries, sour cherries, cucumbers and gherkins, dates, eggplants, figs, pistachios, quinces, walnuts, and watermelons.". Is that enough to answer the question?
