To determine the word whose underlined part differs from that of the other three in pronunciation for each question, let's analyze the words in each question group. Question 1: A. office B. issue C. interview D. qualified The words office, issue, and interview all have the stress on the first syllable. However, qualified has the stress on the second syllable (kˈwɑləfaɪd). The difference in stress pattern is not directly related to the underlined part but based on the information provided the main distinction comes from stress and prefix "ˈɔ", "ɪ", "ɪ" versus "kˈwɑ". However, a closer look indicates the distinction based on prefix sounds is "ˈɔ" (in office) versus "ɪ" (issue and interview) versus "kˈwɑ" (qualified). Among those, the "ɪ" sounds (issue and interview) is less distinct versus the other 2 but "ɔ" and "ɪ" are both vowels so if we have to select one, that would be "kˈwɑ" since it is a consonant-vowel combination that is more distinct than the other 2 options with vowel-only sounds. Hence the answer would be D. qualified Question 2: A. region B. guitar C. imagine D. general The words region, imagine, and general all have the stress on the first syllable (ˈriʤən, ɪˈmæʤən - though imagine has stress on second syllable it starts with unstressed "ɪ", and ˈʤɛnərəl). However, guitar has the stress on the second syllable (gɪˈtɑr). Similar to the previous question, the difference in stress pattern is not directly related to the underlined part but, again, the main distinction is based on the location of the stress. However, that is not what the question asks. Considering the specific sounds (and corresponding letters) the initial sounds (/ri/, /ɪm/, /ʤɛ/, /gi/) in the above words are the key distinction. So A, C, D start with vowels (R, I, GE) whereas B starts with a consonant (GI). Hence B. guitar Here are the analyses and answers: Question 3: Analyze: 'exchange' stressed at second syllable 'discuss' stressed at second syllable 'prepare' stressed at second syllable 'value' stressed at first syllable Therefore, 'value' has a different stress position to other words. Answer: D. value Question 4: Analyze: 'museum' stressed at second syllable 'ancestor' stressed at first syllable 'performance' stressed at second syllable 'opinion' stressed at second syllable Therefore, 'ancestor' has a different stress position to other words. Answer: B. ancestor 5. C. relations 6. C. for 7. A. represent 8. D. Participants 9. A. encourages 10. A. miss 11. C. transformational 12. B. region
