Have students break out into smaller groups (distanced or online) to discuss the possible reasoning for the statement. Front load the activity by letting everyone know that the goal is to learn to ask good questions. After students get some time to discuss get them to come up with yes or no questions. Come back together to answer these questions. Be sure to ask students not to yell out their answers to give opportunity for others to also figure out the riddle. Then have students start to ask questions without giving the exact answer, but showing that they may know the answer. When the time is up, and most students now understand the answer, share the final answer.
