Final answer:
The statement is true as proper identification and a ticket are required to board a plane, which is similar to the ticketing process for a sports event where a unique ticket specifies the seating.
Step-by-step explanation:
The statement 'Only if you have proper identification and a ticket will you be allowed to board the plane' is true. When you travel by air, having proper identification, such as a passport or another form of government-issued ID, in addition to a boarding pass or ticket, is essential. These requirements are in place for security purposes and to ensure that only ticketed and identified passengers board the aircraft. Just like getting into a sports stadium requires a specific ticket that designates your seat, getting on a plane necessitates having the proper documents that verify your identity and your reservation on the flight.
