You will be given a passage, and your task is to generate a Yes/No question that is answerable based on the given passage.

Ex Input:
Salt water chlorination is a process that uses dissolved salt (2,500--6,000 ppm) as a store for the chlorination system. The chlorine generator (also known as salt cell, salt generator, salt chlorinator or SWG) uses electrolysis in the presence of dissolved salt (NaCl) to produce hypochlorous acid (HClO) and sodium hypochlorite (NaClO), which are the sanitizing agents already commonly used in swimming pools. As such, a saltwater pool is not actually chlorine-free; it simply utilizes added salt and a chlorine generator instead of direct addition of chlorine.

Ex Output:
can you use chlorine in a saltwater pool?


Ex Input:
Situated on the continent of Antarctica, it is the site of the United States Amundsen--Scott South Pole Station, which was established in 1956 and has been permanently staffed since that year. The Geographic South Pole is distinct from the South Magnetic Pole, the position of which is defined based on the Earth's magnetic field. The South Pole is at the center of the Southern Hemisphere.

Ex Output:

Ex Input:
A boarding pass is a document provided by an airline during check-in, giving a passenger permission to enter the restricted area of an airport and to board the airplane for a particular flight. At a minimum, it identifies the passenger, the flight number, and the date and scheduled time for departure. In some cases, flyers can check in online and print the boarding passes themselves. A boarding pass may be required for a passenger to enter a secure area of an airport.

Ex Output:

is boarding pass the same as a ticket?
