What responsibilities, if any, do Americans have to promote representative democracy and constitutional government in other nations?
The United States has no responsibility to promote democracy in other countries because that would be intromission in other nations. In today's world, that is not acceptable. Every country is autonomous and has its own right to establish the best form of government their citizens approve.
What the US can do is to be an example of a democratic government by its actions and legislation. It can show other countries the possibilities that democracy offers. However, every country has its own problems and challenges, including the US. That is why it is important to respect the sovereignty of each country.

Answer:
75%
Explanation:
In order to understand this question you need to understand the matching law first. The matching law provides the density of reinforcement or the rate of reinforcement if more than one response is available simultaneously to the individual. Here, two responses are available which are left key, 60 reinforcers per hour, and right key, 20 reinforcers per hour. This provides the ratio between the two reinforcers which is 60:20 or 3:1 in favor of left key. Here, one has to make a prediction only for left key and based on 3:1 ratio it can be said that 75% of pigeon will make their responses on the left key.
