I'll analyze each question and provide the answers. **1. A. slum B. upgrade C. rude D. stunning** Analyze: All options except 'upgrade' have the stress at the first syllable ('slum' at first, 'rude' at first, 'stunning' at first). Answer: B. upgrade **2. A. specialty B. society C. process D. recent** Analyze: All options except 'society' have the stress at the first syllable ('specialty' at first, 'process' at first, 'recent' at first). Answer: B. society **3. A. costume B. cuisine C. manner D. urban** Analyze: All options except 'manner' and 'urban' have the stress at the second syllable ('costume' at second, 'cuisine' at second). 'manner' and 'urban' both have the stress at the first syllable. However, there are two correct options and the questions asks for one correct answer. Since both 'manner' and 'urban' have the same stress position (at first syllable) we can infer that the question is looking for the word that is least different in terms of stress position. Between 'manner' and 'urban', both are the same, but 'manner' comes first, so we should take 'manner' as our answer choice, assuming that this will be compared against other, more 'unique' questions where a different arrangement of first and second stressed syllables is more clearly contrasted, in the given set of 'multiple choice' questions provided by the students. Answer: C. manner **4. A. fascinating B. infrastructure C. manageable D. embarrassing** Analyze: 'infrastructure' has the stress at the third syllable, and 'embarrassing' at the second syllable, while 'fascinating' and 'manageable' both have the stress at the first syllable. However, considering that there are multiple possible answers with two differing stress patterns, we can identify that the words with stress at the second syllable and the words with stress at the third syllable are both unique to the words 'embarrassing' and 'infrastructure'. Thus the words with stress at the first syllable, 'fascinating' and 'manageable', will both be answers, that in contrast to both 'embarrassing' and 'infrastructure', show a difference in stress position. However, 'fascinating' is before 'manageable' so will be our final answer, based on alphabetical order. Answer: A. fascinating 5. C. the / the 6. A. relocate 7. D. can be considered 8. C. has been 9. A. take off b - a - c
