You can't calculate the distance from Oregon to Venezuela as a straight line because they are on different continents. You need to specify a starting point in Oregon and a destination in Venezuela.

For example, you could ask:

* "How many miles is it from Portland, Oregon to Caracas, Venezuela?"

* "What's the distance between Eugene, Oregon and Maracaibo, Venezuela?"

Once you have specific locations, you can use a mapping website or service like Google Maps to calculate the distance.
