I'll analyze each question and provide the answers. QUESTION 11 A scarf B scene c scissors D Scientist Analyze: 'scarf' stressed at first syllable 'scene' stressed at first syllable 'scissors' stressed at first syllable 'Scientist' stressed at first syllable All words have the stress at the first syllable. Answer: No answer choice stands out as having a different stress position, but that's not what the question asks. It seems like the question is asking for which word has the "same" stress position as the others (which is the first syllable). However, in that case, all options would be correct, so I will choose one of them as an example. Answer: A scarf QUESTION 12 A pollution B transport c waste D plastic Analyze: 'pollution' stressed at second syllable 'transport' stressed at second syllable 'waste' stressed at first syllable 'plastic' stressed at first syllable 'pollution' and 'transport' have the stress at the second syllable, while 'waste' and 'plastic' have the stress at the first syllable. Answer: Since 'pollution' and 'transport' are stressed at the second syllable and 'waste' and 'plastic' at the first, they are divided into two groups, but in this case, the question is which word to choose. 'pollution' and 'transport' could be one group. 'waste' and 'plastic' another. For example, A would be a good example of the first group. Answer: A pollution QUESTION 13 A Lived B Braised C picked D organized Analyze: 'Lived' stressed at first syllable 'Braised' stressed at first syllable 'picked' stressed at first syllable 'organized' stressed at first syllable All words have the stress at the first syllable. Answer: Similar to question 11, all words are stressed at the first syllable. Answer: A Lived
