    Section A

    MetroWater is a public utility managing a city's water grid. It operates as an 'open system'.

    Answer options:

    A.

    It operates entirely independently of external environmental factors.

    B.

    It interacts with and responds to its external environment, such as changing weather patterns and regulatory shifts.

    C.

    It restricts data access strictly to internal management personnel.

    D.

    It relies solely on historical internal financial data for decision-making.

    How to approach this question

    Understand systems theory. An open system interacts with its environment (inputs/outputs), whereas a closed system is isolated.

    Full Answer

    B.It interacts with and responds to its external environment, such as changing weather patterns and regulatory shifts.✓ Correct
    In systems theory, an open system is one that interacts with its external environment. A public utility like MetroWater must take inputs from the environment (weather data, population growth, regulations) and adapt its operations accordingly.

    Common mistakes

    Confusing 'open system' with 'open source software' or 'open access security'.
