Which of the following is an architectural barrier described for older buildings affecting physically disabled students?

• A. Carpeted floors with bulky thresholds
• B. Narrow doorways
• C. Modern elevators
• D. Wide, accessible entrances

Answer: (B)

Narrow doorways in older buildings create an architectural barrier for physically disabled students because they physically prevent or severely limit wheelchair and mobility device access. When doorway widths don’t meet accessibility standards, a student may not be able to pass through, turn, or maneuver safely from room to room, which blocks entry to classrooms, restrooms, and common areas. Older structures were not built with current accessibility guidelines in mind, so door frames and openings are often just too tight. Modern elevators and wide, accessible entrances, in contrast, remove these access barriers and support independent movement, making them helpful features rather than barriers. Carpeted floors with bulky thresholds can also pose challenges, but the specific issue described for older buildings is the doorways’ insufficient width hindering passage. To improve access, widening doorways, adding automatic doors, and other retrofits can help meet students’ mobility needs.
