Video Summary

The problem involves arranging cards with three fruit types – apple, cherry, and grapes – into sets of five, and determining which set cannot be rearranged by swapping just two cards to have all cards of the same fruit type next to each other. Examining each option, it is found that set A cannot be rearranged to meet the criteria even after trying all possible swaps, as the apples and grapes cannot be grouped adjacently. However, sets B, C, D, and E can be rearranged successfully with two-card swaps. Therefore, the answer is set A.
