Final answer:
The statement is true; the internal environment includes variables within the short-run control of management, such as labor distribution and marketing strategies, to maintain growth and homeostasis.
Step-by-step explanation:
The statement that the internal environment includes the variables that are within the short-run control of top management is True. In the realm of business and management, the internal environment refers to factors such as employee behavior, corporate culture, and management systems that can be adjusted or managed in the short term. During the short run, certain factors like leases, equipment, and overall business capacity may be fixed, but top management has control over variables such as labor distribution, marketing strategies, and other operational decisions within the constraints of the existing infrastructure. These variables within their control help management to adapt and react to the immediate challenges and opportunities that arise, aiming to maintain growth and dynamic homeostasis in a changing environment.
