Video Summary

In this problem, five kangaroos (A, B, C, D, and E) each have a child (a, b, c, d, and e). Two photos are taken: in the first, two children are next to their mothers, and in the second, three are. After analyzing both sets of conditions, it is determined that initially, mothers A and C switched kids B and D, while mothers B, D, and E cycled kids A, C, and E. This analysis reveals that in the first scenario, A's child is D and C's child is B; thus, in the second scenario, D's child is determined to be child a.
