Final answer:
The passage suggests increased expenses for advertisement development by mentioning the hiring of a reputable ad agency, the creation of multiple concepts, and the engagement of professional actors.
Step-by-step explanation:
The sentences in the passage that indicate increased expenses for developing the advertisement are: "For this purpose, it hired an ad agency reputed for its creative skills." which implies that hiring a reputable agency likely comes with considerable cost; "This agency pitched five different concepts to its client." suggesting that developing multiple concepts is resource-intensive; and "The agency hired professional actors for enacting the scene." as hiring professional actors is typically a significant expense in advertisement production.
