Final answer:
Using the word 'probably' when reasoning by analogy helps to acknowledge uncertainty and account for variables, making the argument more reasonable.
Step-by-step explanation:
Using the word 'probably' when reasoning by analogy is a good idea because it adds a level of uncertainty and acknowledges that the conclusion may not be true. Analogies are comparisons between two things that are similar in some ways but are not identical. Therefore, using 'probably' helps to indicate that the reasoning is not definitive and allows room for potential exceptions or variations.
For example, let's say you are comparing two politicians and using the analogy that since one politician was successful in implementing a policy, the other politician will also be successful. By adding 'probably' to your reasoning, you are acknowledging that there is a chance that the two politicians may have different circumstances or approaches that could affect the outcome.
Using 'probably' in reasoning by analogy helps to account for the nuances and variables involved, making the argument more reasonable and cautious.
