Need help with Ethical thought Experiments & adequacy of the moral theories

I need help with finding examples of thought experiments that I will use to test the moral framework of Immanuel Kants Deontology and Ayn Rands Ethical Egoism/Objectivism. In addition, I need help using those thought experiments and the criteria used for assessing the adequacy of the two moral theories (their explanatory power, completeness, & fundamental value) in order to come to the conclusion of which moral framework is the most morally correct. My teacher hardly gave us any lessons or examples for these so I am completely unsure of how I am supposed to do this.
