Identify the word that contains the r-controlled vowel 'or' as in 'horn'.

• A. or
• B. horn
• C. er
• D. ar

Answer: (B)

R-controlled vowels happen when the letter r follows a vowel and changes how that vowel sounds. The r “bosses” the vowel, creating patterns like ar, er, ir, or, and ur. In the word horn, the o is followed by r, so the o doesn’t stay the simple sound by itself. The r blends with it to make the combined or sound (the vowel is colored by the r). That combination is the r-controlled vowel pattern we’re looking for. That’s why this word is the best example: it clearly contains the or sequence as part of a real word, showing the effect of the r after the vowel. The other options either present different r-controlled spellings (like er or ar) or show the letters or pattern alone, rather than in a word that demonstrates the same sound change.
