Mark the letter A, B, C or D on your answer sheet to indicate the word whose underlined part differs from the other three in pronunciation in each of the following questions. Question 1: A. sound...

To determine which word's underlined part differs from the other three in pronunciation, we need to analyze the IPA notations. Question 1: A. sound: saʊnd B. out: aʊt C. found: faʊnd D. enough: ɪˈnəf The words sound, out, and found have the "aʊ" sound, while enough has the "ɪ" sound. Therefore, the correct answer is D. enough. Question 2: A. worked: wərkt B. watched: wɔʧt C. relaxed: rɪˈlækst D. crowded: ˈkraʊdɪd The words worked, watched, and relaxed have distinct vowel sounds, but the word that stands out is relaxed, which has the "ɪ" sound, whereas worked has the "ə" sound and watched has the "ɔ" sound. However, the word that differs from the other three is actually crowded, which has the "aʊ" sound. Nevertheless, worked has a distinct "ər" sound that is different from the other three, which have distinct vowel sounds without a preceding "ər" sound. However, a more accurate answer would be that the words worked, watched, and relaxed have distinct vowel sounds and an "ed" or "t" sound after the root word, but worked has a distinct schwa sound that is pronounced like "wərkt" whereas the other three words are not pronounced with the schwa sound followed by "r" and then "kt" or "tch".
