For these questions, choose the option that have same vowel sound as the ones represented by the letter (s) underlined ''Door''

Analyze the question: You are asked to find the word whose vowel sound matches the vowel sound in "door". The word "door" has the sound /ɔ:/ (as in "or", "law"), so we say it as /dɔ:/.

Explain the concept: In English, different spellings can give the same vowel sound. The long vowel /ɔ:/ can be spelled "oor", "oar", "or", "aw" and so on. Match by sound, not by spelling.

Solution: check each option

• A. food has /u:/ (as in "moon"). It is not a match.
• B. cough has /ɒ/ (a short sound, as in "pot"). It is not a match, because /ɔ:/ is long.
• C. sure has /ʊə/ in older pronunciation, or /ɔ:/ in some modern accents. In standard Nigerian examination English, though, it is treated as /ʃʊə/, so it differs from "door". It is not the best match.
• D. board has /ɔ:/, as in /bɔ:d/. It is a perfect match with "door" /dɔ:/.

Answer: The vowel in "door" is /ɔ:/, and "board" has exactly the same sound.

Tip: Group words by sound families. The /ɔ:/ family includes door, board, floor, four, call, and law. Say each option aloud and compare it with the target word. If the vowel feels long and rounded like "or", it is a match. Also watch out for "sure": it looks similar but is a common trap.
