These two examples are two similar sentences, in which the contour is nearly the same: the nuclear pitch accent is a low plateau (L*), which continues on the first postaccented syllable, and finally there is a rise on the last syllable. The difference between these two sentences is the height of the peak at the end of last syllable: in the first one, it is much higher and the sentence is interpreted as an anti-expectative question (LH%), whereas in the second one, the peak is less high and is thus interpreted as an obviousness statement instead (LM%).
