Host Meg Wolitzer presents three stories about finding solutions to complex problems, and to simple ones. T. C. Boyle tackles evolution and government intervention in “Top of the Food Chain,” read by Zach Grenier. In Matthew Ryan Frankel’s “Carapace,” a young boy struggles with feelings at a family funeral—with the help of some crabs. The reader is Philip Estrera. And a young woman traveling between two worlds and two families has to deal with what to put in “The Suitcase” by Meron Hadero. The reader is Renée Elise Goldsberry. The show also includes an interview with Hadero.
