Given that my friend has differing viewpoints on the bundles (5,6), (6,6). This indicates that his or her tastes are not consistent. If he or she is unconcerned about both bundles, it signifies that they provide the same level of satisfaction and are ranked similarly. On the other hand, the second bundle has more of both goods. As a result, he/she must favour the second bundle above the first, based on the monotonic assumption.
