Final answer:
Without additional context or details, it is impossible to provide the number of other film sites lined up for a particular film production scenario. More information is needed to answer this question accurately.
Step-by-step explanation:
In the context of the question 'How many other film sites had they lined up?', it is clear that the question pertains to a specific scenario related to film production or location scouting. Since the question presents multiple choices but does not provide enough information or context to deduce a correct answer, it's not possible to provide an accurate response without additional details or a reference to a specific text, film, or scenario. In film production, scouting and securing film sites is a critical aspect of the pre-production phase. Producers and location managers often work together to identify and arrange for various filming locations that align with the requirements of the script.
