Figure 1 shows 9 DANGOs (Japanese dumplings) and 8 KUSHIs (straight skewers). On each skewer, there are 3 (brothers of) dumplings. Remove 2 out of the 9 dumplings to other positions and skewer these dumplings so as to increase the number of skewers from 8 to 10. On each skewer, there should be 3 dumplings, and there should not be 2 or 4 dumplings. There will be three forms of answers in this quiz. The answers will be seen in Figure 2 (page 103) of the text.
