I wouldn't want to write the essay for you, but I can help you a bit.
1. Health Care. What about health care would you want to write about? It could be about anything relating to health care! Look up the keywords "health care" for ideas if you feel lost.
2. Research. Research is important when it comes to essays. In fact, the question specifically tells you to write a research-based essay. Once you settle on a topic, look up a few websites relating to that topic. Make sure to cite your sources!
3. Argumentative. An argumentative essay works best with controversial topics. You want to persuade the reader to think the way you do. That's the point of an argumentative essay.
