Answer 2

Within a free trade zone, the products from one nation being sold to another (both in the free trade zone) will become cheaper as they will not incur import taxes, and most likely will not be subject to quotas - this will increase demand within each country for goods supplied from the other countries in the trade zone, as the price level is lower.
