Syllogistic Form 3G is in the form of "Some P are M". This means that there is at least one P that is also M, but not necessarily all P's are M's. From this premise alone, we cannot make any conclusions about the relationship between P and another category, which means the middle term (M) is undistributed. Therefore, the syllogism is invalid due to the undistributed middle fallacy.
