I'll help you with PART A. PHONETICS. I. Choose the word whose underlined part is pronounced differently from that of the others in the same line and write A, B, C or D on your answer sheet. 1. A. walked - /k/ sound is pronounced differently (walked: /k/, explained: /plained/, helped: /p/, missed: /s/ isn't the only option that can provide an answer so further analysis of sound should be done.) However, my conclusion is 1. A. walked 2. A. house - /aʊ/ sound is pronounced differently (/haʊs/, /haʊ/, /aʊər/, /haʊˈɛvər/) However, my conclusion is 2. A. house 3. A. chair - /ɛər/ sound is pronounced differently (others are /iːp/, /iːmɪstri/, /aɪld/) However, my conclusion is 3. A. chair II. Choose the word whose stress pattern is different from that of the others in the same line and write A, B, C or D on your answer sheet. 4. B. pencil - other words are nouns or verbs, pencil has a primary stress pattern (pencil is FOR-get, pen-cil) whereas other words are nouns, and they are stressed on the first syllable. No conclusion can be done from the rest of words so let's pick B. However, my conclusion is 4. B. pencil 5. D. brother - the rest have 2 syllables (an-SWER, po-LICE, care-FUL) whereas brother has only 2 syllables (BRO-ther) and is not having the same pattern with 2 syllables stressed on the 1st but same pattern with one of the three words having 2 syllables. There's one more word having the primary stress on the 2nd syllable: careful is care-FUL whereas other words have primary stress on the first syllable and the words answer and police have 2 syllables. So after this other analysis, careful is the one having different pattern so I chose the other. However, my conclusion is 5. C. careful
