ANSWER: first-come/first-served
EXPLANATION: This form of allocating tickets by forming a line is an example of first come/first served. As the name suggests, the first person to come and be in the line will get the opportunity to hold or buy the ticket. If all the tickets are sold then the people still standing in the line will not be given an opportunity to see the movie. Lottery is a form of distribution where luck is considered to win the seat at the movie theater. Sharing equally will also not be the option as the seats are not equally distributed according to the number of people standing in the line.
