Answer:
India, Pakistan, and Iran participate the most in agriculture.
Step-by-step explanation:
As an 8th grader who had visited states in the National Geographic Bee, Iran, India, and Pakistan are the correct answers for several reasons. First, they are agriculturally advanced because these countries rely on groundwater due to the lack of clean water in these locations. Second of all, the soil conditions in these countries in particular are far worse, so they need to perform a lot of agricultural maintaining. Lastly, these countries for thousands of years have used irrigation systems for agriculture. The Harrapans who are from India and Pakistan are known to have developed farming. For these reasons, Iran, India, and Pakistan participate the most in agriculture in Southwest Asia.
