The area in the world that could be said to have a comparative advantage in oil production is Saudi Arabia
<h3>Who has the comparative advantage in the production?</h3>
If someone can create something for less money than anyone else, they have a comparative advantage. Comparative advantage is different from superiority in a given field.
The ability of an economy to produce a specific good or service at a lower opportunity cost than its trading counterparts is known as comparative advantage. Comparative advantage is a theory that explains why businesses, nations, or people might gain from trade.
Recall that the potential cost of creating commodities was used to define comparative advantage.

Answer: Snowball sampling
Explanation: Snowball sampling also called chain referral sampling occurs when a research participants request the assistance of other participants for a test or study. It is used where potential participants are hard to find. In snowball sampling a researcher picks the first few samples and either recruits them or asks them to recommend other subjects they know who fit the description of samples needed. This referral technique goes on and on, increasing the size of the respondent population like a snowball rolling down a hill until the researcher has sufficient data to analyze. It's called snowball sampling because once you have the ball rolling, it picks up more “snow” along the way and becomes larger and larger. As evident in the above question Kerry Sobiski employed the assistant of students to recommend other students they have drank with in the past two month, this assistant cascaded further until sufficient enough data was gardered. Without doubt this sampling method is the snowball sampling method.
