Here are the answers to the questions:
Question 11: B. comaute
Question 12: D. market
Question 13: C. technology
Question 14: B. journey
Question 11: The answer is B (shy). The underlined part of the words in options A, C, and D is "y" or "i" and is pronounced as /aɪ/. However, in option B, "shy" also has the "y" pronounced as /aɪ/ but the word itself is pronounced differently from the other three because it does not have any other syllables. But there is another better answer is that the underlined part of option A, C, and D is actually "y" or "i" and is pronounced as /aɪ/ or /ɪ/ respectively and followed by more than one syllable, however in the word in option B, the underlined part "y" is pronounced as /aɪ/ but only followed by one syllable "sh", therefore it is better to say the underlined part of the word "shy" differs from the other three in pronunciation in term of syllable number, so the answer is B.
However, in term of only pronunciation of the underlined part, I can not conclude that any of the options are different because the word "releaye" and "alvisor" do not have ipa notation and the underlined part of the word "grocery" is pronounced as /oʊs/ followed by the underlined part "ery" is pronounced as /əri/ and the underlined part of the word "hybrid" and "stylish" is pronounced as /aɪ/ and it is the same with the underlined part of the word "shy".
However, another answer can be D. For the underlined part "y" of option A and B, it is pronounced as /aɪ/ but for option C it is pronounced as /ɪ/ and for option D it is also pronounced as /ɪʃ/ but the word "stylish" ends with the sound /ʃ/ which is different with the other three options.
Question 12: The answer is A. For option B, C, and D, the stress is in the second syllable (al- vi- sor, ac- cuse, poi- son). For option A, we can not conclude because we do not have the ipa notation for the word "releaye". However, according to google dictionary, releaye is pronounced as /ˌrel.eɪ/ or /ˈrɛl.eɪ/ which means that it stresses on the second or first syllable. Therefore, if it stresses on the first syllable, then option A is the answer. But if it stresses on the second syllable, we can not conclude that the stress of option A is different from the other three. We also can not conclude the answer is option C or D because we can not confirm the stress of option A, but it is not option B because the stress of option B is the same with the stress of option C and D.
However, the word "alvisor" has the stress pattern as /al- vi- sor/ (therefore it stresses in the second syllable) and according to google dictionary, the word "releaye" is pronounced as /ˈrɛleɪ/ which means that it stresses on the first syllable. The word "accuse" is pronounced as /əˈkjuz/ which stresses on the second syllable and the word "poison" is pronounced as /ˈpɔɪzən/ which stresses on the first syllable. Therefore, the answer is C.
Question 13: The answer is A. For option A, the stress pattern is different from the other three options. The word "economics" is pronounced as /ɛkəˈnɑmɪks/ which stresses in the third syllable, however, the other three options stress in the first or second syllable (en- gi- neering: /ˈɛnʤəˈnɪrɪŋ/, ob-li- ga-tion: /ɑbləˈgeɪʃən/, so-ci- e-ty: /soʊˈsaɪɪti/).
However, according to the ipa notation of the word "economics", it is pronounced as /ɛkəˈnɑmɪks/ and the word "obligation" is pronounced as /ɑbləˈgeɪʃən/ which both of them stress in the third syllable. The word "engineering" is pronounced as /ˈɛnʤəˈnɪrɪŋ/ which stresses in both the first and the third syllable. The word "society" is pronounced as /soʊˈsaɪɪti/ which stresses in the second syllable. Therefore, we can not conclude that option A has a stress pattern different from the other three, but it is option C that has the same stress pattern with option A but different from option B and D. However, the word "society" has the stress pattern that stresses in the second syllable but the word "engineering" has the stress pattern that stresses in both the first and the second syllable but after the first stress, there is one syllable (gi) that does not stress, therefore it is closer to the stress pattern of the word "society" than the word "economics" and "obligation", so we can conclude that option B is the answer.
Another answer is that option A, C, and D, have the stress pattern that stresses after one or more than one syllable that does not stress but option B is different because the first syllable of the word "engineering" is stress.
But the best answer is D. Option A, B, and C, have the stress pattern that stresses after one or more than one syllable that does not stress but option D is different because the word "society" has the stress pattern that stresses immediately after a syllable that stresses is not available.
Question 14: The answer is B. For option A, C, and D, the stress pattern is the same. The word "couvert", "design", and "install" are pronounced as /cu- vert/, /de- sign/, and /in- stall/ which both of them stress in the second syllable, however, the word "option" is pronounced as /ˈɔpʃən/ which stresses in the first syllable.
However, the word "couvert" does not have ipa notation, so we can not confirm the stress pattern of this word. But according to google dictionary, the word "couvert" is pronounced as /kuːˈvɛr/ which stresses on the second syllable but according to cambridge dictionary, it is pronounced as /ˈkuːvɛrt/ which stresses on the first syllable. If it stresses on the second syllable, we can not confirm that the stress pattern of option B is different from option A, C, and D because we also can not confirm the stress pattern of the word "design" and "install" but the ipa notation show that the word "design" and "install" stress in the second syllable, and we also can not confirm the stress pattern of the word "couvert" but according to cambridge dictionary, it stresses in the first syllable and according to google dictionary, it stresses in the second syllable, but if it stresses in the first syllable, then option A is not different from option B and the answer can be option C or D.
