To answer these questions, we need to analyze the pronunciation of each word, focusing on the main stress (indicated by the "ˈ" sign) and the syllable pattern. 1. The main stress patterns are as follows: - A. ghost: goʊst (no main stress on a separate syllable) - B. technical: ˈtɛknɪkəl (main stress on the first syllable, but the word has four syllables: tec-ni-cal-l) - C. childhood: ˈʧaɪldhʊd (main stress on the first syllable, but the word has two syllables: child-hood) - D. exhibition: ɛksəˈbɪʃən (main stress on the third syllable, ex-hi-bition) The words technical, childhood, and exhibition have main stresses on the first or a non-initial syllable and have more than one syllable. In contrast, the word "ghost" has no main stress on a separate syllable, making it distinct in terms of stress pattern. 2. The main stress patterns are as follows: - A. exist: ɪgˈzɪst (main stress on the second syllable) - B. collect: kəˈlɛkt (main stress on the second syllable) - C. event: ɪˈvɛnt (main stress on the second syllable, but the word has two syllables: e-vent) - D. excellent: ˈɛksələnt (main stress on the first syllable, but the word has three syllables: ex-cel-lent) The words exist, collect, and event have main stresses on the second syllable and have fewer syllables than excellent. However, what makes the word "excellent" distinct is the main stress on the first syllable, unlike the other three words. Therefore, the correct answers are: 1. A. ghost 2. D. excellent To determine the words that differ from the others in stress position, let's analyze each group. 3. Analyze: 'passion' stressed at first syllable 'prepare' stressed at second syllable 'receive' stressed at second syllable 'accept' stressed at second syllable Therefore, 'passion' has a different stress position to other words. Answer: A. passion 4. Analyze: 'encourage' stressed at second syllable 'direction' stressed at second syllable 'industry' stressed at first syllable 'effective' stressed at second syllable Therefore, 'industry' has a different stress position to other words. Answer: C. industry
