Mark the letter A,B,C or D to indicate the word whose underlined part differs from the other three in pronunciation in each of the following questions. 3. A. ancient B. concentric C. electrician D. pre...

3. The words "ancient", "concentric", "electrician" have the same pronunciation of the underlined part "ci" as /i/ or /ɪ/. However, "precious" has the pronunciation of the underlined part "ci" as /i/ with stress (ˈprɛʃəs). But looking at the options, we can see that A, B, and C have the underlined part as "ci" while D is "ci" in "precious". But it seems the underlined parts are different from each other. However, looking closely at the options A, B and C we see they have "c" followed by some letter. But the word precious has "ci". However the letter "c" in A, B and C is followed by "e" in A, "e" in B and "e" in C but in "precious" it is followed by an "i". So the word "ancient" has "ce" the same as B, C but "precious" has "ci". So "ancient" has the same underlined part as B, C. So we have two "ce" versus one "ci" versus one unknown, which is "ancient", B, C. However we need to compare the other 3 options. Since we see the letters that "c" is followed by in "ancient", B, C, we must look at what letter "c" is followed by in "electrician". Since we see it is "e", then the underlined part in "electrician" is the same as "ancient" and "concentric". Now since "ancient", "concentric" and "electrician" are all the same, then the other one must be different. However, we still don't know what the underlined part in "precious" is. We see that it is "ci" since "precious" has "ci". So "ancient", "concentric" and "electrician" have "ce" but "precious" has "ci". Then the underlined part in "precious" is different from "ancient", "concentric" and "electrician". Therefore the answer is D. "precious". 4. The words "towel", "downtown" and "superpower" all have the underlined part "ow" as /aʊ/. However, the word "knowledge" has the underlined part "ow" as /oʊ/ (oʊ doesn't exist in the ipa_notation, the correct is ɔʊ - note /ɔʊ/ and /aʊ/ is different) no the word is "ˈnɑlɪʤ" the underlined part "ow" is /aʊ/ no the word is "ˈnɑlɪʤ" the underlined part is not "ow" it is "ow" for "towel", "downtown" and "superpower" but the word knowledge doesn't have the letter "ow" but "kn". So "kn" in knowledge versus "ow" in "towel", downtown, superpower. Since "towel", "downtown" and "superpower" all have the same underlined part "ow", then "knowledge" is the answer.
