Which term describes a system for blind readers using raised dots?

• A. Sign Language
• B. Gestures
• C. Culture
• D. Braille

Answer: (D)

Braille is a tactile writing system that uses raised dots to convey letters, numbers, and punctuation for blind readers. Each character is formed by a cell of dots arranged in a 2 by 3 pattern, which readers feel with their fingertips to decode the text. This enables literacy and independent reading for people who cannot rely on visual print. It’s distinct from sign language, which is a visual-gestural language using hand shapes; from gestures, which are general movements used to communicate; and from culture, which refers to shared beliefs and practices. Because the system described is specifically the raised-dot method used by blind readers, the correct term is Braille.
