To determine which word has a different sound in the underlined part, we need to analyze the IPA notation for each option.
1. A. treasure: ˈtrɛʒər
B. closure: ˈkloʊʒər
C. exposure: ɪkˈspoʊʒər
D. ensure: ɪnˈʃʊr
Answer: D. ensure (The underlined part is "ˈʒ" in A, B, and C, but "ʃ" in D, and the sound is different, also "ʒ" is a voiced postalveolar affricate and "ʃ" is a voiceless postalveolar fricative, but "ʒ" is a voiced postalveolar fricative in the above words, so the sound of "ʒ" and "ʃ" are the same, only "ʒ" and "ʊr" vs. "ʒər" are different, also "ʊr" and "ʒər" is different too, so "ʊr" and "ʒər" make the sound different. So, we can pick the correct answer easily).
2. A. happy: ˈhæpi
B. hard: hɑrd
C. similarity: sɪməˈlɛrəti
D. talent: ˈtælənt
Answer: B. hard (The underlined part is "æ" in A and D, but "ɑ" in B, so the sound is different. And in C, the "ɛ" is not similar to "æ", "ɑ" and the location of "ɛ" is different from "æ" and "ɑ", and "i" is not similar to "æ", "ɑ" too).
3. A. chorus: ˈkɔrəs
B. brochure: broʊˈʃʊr
C. machine: məˈʃin
D. chef: ʃɛf
Answer: A. chorus (The underlined part is "ʃ" and "ʊr" or "ʃʊr" in B, C and "ʃɛf" in D, but "rəs" in A, so the sound is different).
4. A. treasure: ˈtrɛʒər
B. vision: ˈvɪʒən
C. discussion: dɪˈskəʃən
D. decision: dɪˈsɪʒən
Answer: C. discussion (The underlined part is "ʒ" in A, B, and D, but "sk" in C, so the sound is different).
5. A. exhibition: ɛksəˈbɪʃən
B. action: ˈækʃən
C. question: kˈwɛʃən

Answer: C. question (The underlined part is "ʃ" in A, B, and D, but "ʃ" is the same, but the "wɛ" is not similar to "bɪ", "æk" and "dɪ", so the sound is different).
