 ## Exercises
 
-::::{dropdown} Challenge Title
+::::{dropdown} Which of the following statements are True/False?
+:open:
+
+a. 2i2c-managed hubs are only available via a single cloud provider.  
+b. A hub can be accessed and used by anyone who knows its URL.  
+c. Software environments are inflexible and irreproducible.  
+d. 2i2c provides operations support for your hub.
