S = <sunny, warm, high, same>. Training data = <sunny, warm, normal, same> => Yes (positive example). How will S be represented after encountering this training data?

Correct Answer: <sunny, warm, ?, same>
Initially the S hypothesis states that if the conditions are sunny, warm, high and same, then only the example will be positive. But it encounters an example that contains normal instead of high and is a positive example. Hence, that attribute is not specific and it needs to be generalized.
