Final answer:
A 4 bedroom house with only 1 bathroom would be considered functionally obsolete, as it does not align with modern standards of multiple bathrooms for a house of that size. Functionally obsolete refers to properties that lack utility compared to current norms and expectations.
Step-by-step explanation:
A 4 bedroom house with only 1 bathroom would most likely be considered functionally obsolete in today's standards. Functionality in housing typically reflects the expectations and needs of the time, and modern standards generally require multiple bathrooms for a house of that size. The historical context you've provided indicates that even though shared living spaces were common in the past, our current housing expectations have evolved to prioritize more private and divided spaces, particularly for sanitary facilities like bathrooms.
The term functionally obsolete refers to a property that, while still occupying its original structure and being capable of use, is lacking in utility compared to modern standards. This could include aspects such as layout, design, or amenities (e.g., number of bathrooms). The provided examples, though illustrative, are not related to housing and do not directly contribute to answering the question.
