O M'chael makes no progress towards solving the problem until X = X1. Between X = X1 and X = X2, he makes no further progress. But at X = X2 he suddenly achieves a breakthrough, and at x = x3 he proceeds to complete the problem. O M'chael makes progress toward solving the problem until X = X1. Between X = X1 and X = X2, he makes no further progress. But at X = X2 he suddenly achieves a breakthrough, and at X = x3 he proceeds to complete the problem. 0 M'chael makes progress toward solving the problem until X = X1. Between X = X1 and X = x2, he makes no further progress, and never completes the problem. O M'chael makes no progress toward solving the problem until X = X1.
