Question I: Circle the letter A, B, C or D to indicate the word whose underlined part is pronounced differently from that of the others in the group. A. SURgical B. SURround C. SURrender D. SURvival...

Based on the given International Phonetic Alphabet (IPA) notation, let's analyze the pronunciation of each word. The underlined part "SUR" in each word can be compared as follows: - SURgical: ˈsərʤɪkəl - SURround: səraʊnd - SURrender: sərˈɛndər - SURvival: sərˈvaɪvəl Comparing the underlined part "SUR", we can see that: - The words SURgical, SURrender, and SURvival have the same pronunciation for the "SUR" part, which is /sər/. - The word SURround, however, has a different pronunciation for the "SUR" part, which is /sər/ for the unstressed and aʊ in SURround (instead of the sound of /ər/ in the other three options). Nevertheless, sər in SURround is also the same sound. The stressed syllable is the second "round". Hence, the real differing sound comes from "ound". Thus, A or C or D can be correct answers (actually all three are correct since the differing sound of "ound" can not be ignored). - But B is definitely the best answer to the question: whose underlined part is pronounced differently from that of the others.
