Here are the answers with explanations:<br /><br />1. **A. brochure** The underlined part in "brochure" is pronounced /ʃ/, while in the other words (exchange, purchase, armchair) it's pronounced /tʃ/.<br /><br />2. **B. illegal** The underlined part in "illegal" is pronounced /ˈɪl/, while in the other words (information, itinerary, imitation) it's pronounced /ɪ/.<br /><br />3. **D. desert** The underlined part in "desert" (the noun meaning a sandy area) is pronounced /ˈdɛzərt/, while in the other words (hesitate, species, visit) it's pronounced /z/. Note that "desert" (the verb meaning to abandon) has a different pronunciation altogether.<br /><br />4. **A. urgent** The underlined part in "urgent" is pronounced /dʒ/, while in the other words (encourage, suggest, agree) it's pronounced /dʒ/. (While subtle differences might exist depending on accent, the key difference lies in the stress and vowel sound preceding the 'g' sound).<br /><br />5. **D. access** The underlined part in "access" is pronounced /s/, while in the other words (admire, animal, landscape) it's pronounced /z/.<br /><br /><br />Therefore, the circled words should be A, B, D, A, and D respectively.<br />
