Consider that you are a civilian resident living on the Chatham Island in New Zealand where a long-finned pilot whale stranding event with 100 beached whales is happening and maybe have even been participating in the response to the strandings. Raise specific questions that you may have for the local government or researchers about the stranding. Argue for an alternate hypothesis as to why the event occurred.
