Based on the provided IPA notations, we can analyze the pronunciation of each word to find the one with a different sound in the underlined part.

1. A. treasure (ˈtrɛʒər)
   B. closure (ˈkloʊʒər)
   C. exposure (ɪkˈspoʊʒər)
   D. ensure (ɪnˈʃʊr)
   The underlined part is "sure" for A, B, and C. The word "ensure" has a different sound in the underlined part, which is "shure" (ʃʊr) instead of "sure" (ʒər). So, the answer is D. ensure.

2. A. happy (ˈhæpi)
   B. hard (hɑrd)
   C. similarity (sɪməˈlɛrəti)
   D. talent (ˈtælənt)
   The underlined part is "y", "rd", "ity", and "ent" respectively. Although all of them have different sounds, "y" in happy has a unique sound compared to the other options. So, the answer is A. happy.

3. A. chorus (ˈkɔrəs)
   B. brochure (broʊˈʃʊr)
   C. machine (məˈʃin)
   D. chef (ʃɛf)
   The underlined part is "us" in A, and "u" in B, C, and D have different pronunciations. However, the word "chorus" has a distinct sound of "us" compared to the other options. So, the answer is A. chorus.

4. A. treasure (ˈtrɛʒər)
   B. vision (ˈvɪʒən)
   C. discussion (dɪˈskəʃən)
   D. decision (dɪˈsɪʒən)
   The underlined part is "sure" for A and "ision" for B, and "sion" for D. Although "ion" has a different sound, the word "vision" has a distinct sound of "i" in the underlined part. So, the answer is B. vision.

5. A. exhibition (ɛksəˈbɪʃən)
   B. action (ˈækʃən)
   C. question (kˈwɛʃən)
   D. tradition (trəˈdɪʃən)
   The underlined part is "tion" for all of them, but the word "exhibition" has an extra sound of "hi" in the underlined part. So, the answer is A. exhibition

Here are the answers to the exercises:

1. B. artist (The other options are musical instruments.)
2. A. portrait, B. opera, and C. camera, D. photograph are all related but &#x27;camera&#x27; and &#x27;photograph&#x27; are more closely related to each other, so &#x27;opera&#x27; does not belong to the group (The other options are related to visual arts or photography, while opera is a form of performing arts.)
   However, a stronger argument can be made for &#x27;camera&#x27; and &#x27;photograph&#x27;, so B. opera and C. camera could also be argued but more likely  B. opera. So 
3. C. ballet (The other options are music genres.)
4. B. film producer (The other options are artists, while a film producer is more of a behind-the-scenes professional.)
5. C. canvas (The other options are drawing tools, while canvas is a medium for art.)
