Answer:
Claire produces beef and Dag produces corn
Explanation:
Based on the information provided within the question I think it is safe to say that in order to maximize their total output Claire produces beef and Dag produces corn. This is because Claire's beef to corn ratio is 1:5 while Dag's is 1:6 therefore Claire's beef production is more efficient than Dag's, while Dag's corn production is more efficient than Claire's. Which is why each one should focus on what they are best at.
