Answer:
1) Option A. differences in values
2) Option C. Tariffs and import quotas generally reduce economic welfare
Explanation:
1) Difference in values which can also be called value conflicts are due to variations in belief systems. I.e. when the belief systems of two groups do not allign. While Antonio believes that government programmes should be reduced because they cause more harm than good, Caroline is of the opinion that despite the inefficiency of government programmes, they are still necessary for the less fortunate. This disagreement is as a result of value conflict.
2) Both economists agree on the inefficiency of government programmes. The focal point of Caroline's argument is that government's intervention in the economy is needed for the less fortunate. Based on this premise, two economies chosen at random will most likely agree to the proposition that tariffs and import quotas generally reduce economic welfare.
