Find the word which has a different sound in the part underlined. A. st$$dy B. r$$bber C. s$$bject D. calc$$lator

To determine the word with a different sound in the underlined part, we'll compare the IPA notations of each word, focusing on the part that corresponds to the underlined "u" in the original question. - A. study: The IPA notation is ˈstədi. The "u" corresponds to the ʊ sound but is represented as ə in this case, indicating a schwa sound (a neutral, mid-central vowel sound). - B. rubber: The IPA notation is ˈrəbər. Similar to "study," the "u" in "rubber" is also represented as ə, denoting a schwa sound. - C. subject: The IPA notation is ˈsəbʤɪkt. Here, the "u" is represented as ʊ, which would typically correspond to the "u" sound in "put" or "cook." - D. calculator: The IPA notation is ˈkælkjəleɪtər. The "u" in this word is also represented as ə, indicating a schwa sound, similar to "study" and "rubber." Comparing these pronunciations, we find that options A, B, and D have the underlined "u" represented as a schwa sound (ə), while option C ("subject") has its "u" represented as ʊ, indicating a distinct sound from the others. However, the question asks for the word which has a different sound in the part underlined, implying we're looking for a difference within the specific underlined part across the given options. Given that, the question seems to be asking for the option that does not follow the pattern of the others in terms of the sound represented by "u". Since "subject" is the only one with a distinct "ʊ" sound for its "u" part, but considering the schwa sound is the most common pattern among the given options, the interpretation might actually point towards "subject" having a different sound.
