Concept:The underlined letters "ai" in "tailor" produce the long vowel sound /eɪ/, so the correct option must contain the same vowel sound.
Explanation:Say the word "tailor" aloud and listen carefully to its vowel sound.
The letters "ai" combine to form the diphthong /eɪ/, just like the sound in "day" or "say".
Now check each option one by one.
Option A: "torn" is pronounced with the vowel sound /ɔː/, which is different from /eɪ/.
Option B: "dent" has a short vowel sound /e/, so it does not match.
Option C: "orchard" contains the vowel sound /ɔː/, similar to "torn", not /eɪ/.
Option D: "partake" is pronounced as /pɑːˈteɪk/, and its second syllable "take" carries the sound /eɪ/.
Therefore, "partake" shares the same vowel sound as the underlined letters in "tailor".
Answer:D. partake
