I have multiple responses to the same question. I want you to summarize the different responses into a dictionary with unique responses as key and their frequency as value. Ignore syntactic differences, singular vs plural, and spelling variations.
Your response should only include the json requested so that it can be parsed easily with the python routine: `json.loads()`. No yapping!
