Which is a noted drawback of interactive whiteboards?

• A. Needs dimly lit venue
• B. Requires no training
• C. Works perfectly in all lighting
• D. Completely inexpensive

Answer: (A)

A key idea here is how lighting affects the visibility of the projected image on an interactive whiteboard. These systems typically rely on a projector to cast content onto a whiteboard surface, and the clarity of what you see depends on the room lighting. In a dimly lit or controlled lighting environment, the image has good contrast and is easy to read and interact with. But in a bright room, glare and reflections can wash out the projection, making it hard to see the content and select with accuracy. That makes needing a dimly lit venue a real drawback. The other statements don’t fit: interactive whiteboards usually require some training to use effectively, they don’t work perfectly in all lighting conditions, and they’re not completely inexpensive due to equipment, maintenance, and software costs.
