Answer:
The answer is: E) workers in Alzania have higher productivity due to better education and training.
Explanation:
Alzania and its neighbor both produce cotton and they both have the same amount of workers in the production of cotton. If Alzania is able to produce more cotton (or any type of product) using the same amount of resources (in this case labor) than its neighbor, we can conclude that Alzania does have an absolute advantage in that industry.
This absolute advantage exists because Alzania's workers are more productive than their neighbor's workers.
For example, lets say both countries have 5,000 cotton workers. Alzania produces 100 tons of cotton per worker, while its neighbor only produces 80 tons of cotton per worker. That means Alzania's workers are more productive, and labor usually gains productivity through education or training.
