Final answer:
The answer to the student's question related to building's issues of maintenance, deterioration, alterations, additions, and renovations is 'Age'. The passage highlights several indicators of an aging building that requires such attention.
Step-by-step explanation:
The passage you are referring to seems to highlight the age of a building and how it affects various aspects such as maintenance, deterioration, alterations, additions, and renovations. When considering these factors, the correct choice is (d) Age. The passage mentions things like the discoloration of ages, fungi overgrowth, and the preservation of masonry despite extensive decay. This emphasizes that over time, buildings can show signs of aging which affect their structure and require maintenance. In contrast, construction, design, and foundation deal with more initial stages of a building's life or its structural support, rather than its ongoing condition and the modifications it might undergo over time.
