Final answer:
Middle managers generally do not make long-range strategic decisions; instead, they implement the strategies determined by higher-level executives.
Step-by-step explanation:
The statement 'Middle managers make long-range strategic decisions about the firm's products and services' is generally B) false.
Middle managers are typically responsible for implementing the long-range strategic decisions made by top executives, such as the CEO and other members of senior management.
While middle managers may contribute to strategy by providing valuable insights and feedback, they are not ordinarily the ones making these high-level decisions.
Instead, they focus on managing day-to-day operations and short-term goals that align with the long-term strategies set forth by higher-level executives.
