All four options listed can contribute to improving your counterargument, but if you had to choose one option to receive one point, analyzing opposing claims would likely be the most beneficial. This involves carefully examining and evaluating the arguments and evidence presented by the opposing side in order to identify weaknesses or flaws that can be addressed in your counterargument. By thoroughly analyzing opposing claims, you can develop a better understanding of the strengths and weaknesses of your opponent's position, allowing you to effectively challenge their argument and present a strong counterargument.
