Please answer the questions below. Thank you.

As you drive up Rte. 99 through the farm belt of central California there are miles and miles of crop producing agricultural fields. Nearly 100% of USA-grown almonds are grown in California. Why do you suppose these specific fields are used solely for producing almonds when they could be divided into sections to also produce grapes, oranges, apples etc.? (think comparative advantage).

Assume that you're considering opening a trendy clothing boutique. How would comparative advantage come into play with manufacturers? Distributors? Sales personnel?
