Braille letters without one word contractions are represented by which set?

• A. A, I, O
• B. Phoric
• C. Snellen eye chart
• D. Trophic

Answer: (A)

In Braille, there are two systems: uncontracted (Grade 1) and contracted (Grade 2). In Grade 2, many common words have contractions to shorten text, but letters that are themselves standalone one-word terms aren’t replaced by contractions. The only standard English one-letter words are “a” and “I,” and “O” is often used as an interjection as a single-letter word as well. Because these letters function as words on their own, they appear in Braille as the plain letter signs rather than as contractions. So the set of Braille letters that do not use one-word contractions is A, I, and O. The other options refer to concepts that aren’t related to how Braille contractions work.
