Find three products in your home—food, clothing, appliances, electronics, etc. in your discussion post, list these three products identifying where they were made and where you purchased them.

speculate how the items arrived at the store. what modes of transportation do you think were used?
why do some goods and ideas travel more easily than others?
what would happen if we no longer traded with other countries?
how might a particular major historic event have impacted the transportation

Here are three products that I found in my home. 
1. Food : Canned Goods and Juice
2. Clothes
3. Kitchen Utensils
In general, we all bought these products in the malls, and most of these are made here in our country since these are just local products. In addition, some of the clothes are also imported from other countries.
How these products arrived in the store undergone several processes especially if it is imported. These would still undergo strict checking especially for the food and drinks if it is safe enough for consumption. The modes of transportation for these products to arrive may include several transportation, depending on the company that handles it. It may be through land, air or water.
Some goods and ideas travel faster than the other because it depends on the supply and demand. For example, the food. Foods have expiration dates and also needed to be delivered immediately, and foods are of high demand.
If we would no longer trade with other countries, our economy will not develop and we would not be able to experience imported products and we won't be able to export ours as well. 
Hope this answer helps.

The answer would be b.
