To determine the odd one out for each group, I will analyze the pronunciation of each word and look for patterns or differences.
1. A. alarming: əˈlɑrmɪŋ, B. diversity: dɪˈvərsɪti, C. serious: ˈsɪriəs, D. natural: ˈnæʧərəl
- The words 'alarming', 'diversity', and 'serious' have a strong stress on the second syllable or have an unstressed first syllable, whereas 'natural' has a strong stress on the first syllable. However, 'diversity' has a different vowel sound in the first syllable. 'Alarming' and 'serious' have the same vowel sound (ɪ) in their stressed syllables. Considering these points, 'natural' stands out due to its stress pattern, but 'diversity' also stands out due to its different vowel sound.
- The odd one out: 'diversity'
2. A. remove: riˈmuv, B. habitat: ˈhæbətæt, C. animal: ˈænəməl, D. plants: plænts
- The words 'habitat', 'animal', and 'remove' have a strong stress on the second or first syllable with an unstressed second or first syllable respectively, whereas 'plants' has a strong stress on the first syllable and no unstressed syllable. 'Plants' stands out due to its lack of unstressed syllables.
- The odd one out: 'plants'
3. A. protect: prəˈtɛkt, B. hunt: hənt, C. survive: sərˈvaɪv, D. problem: ˈprɑbləm
- The words 'protect', 'hunt', and 'survive' have an unstressed first syllable (schwa sound), whereas 'problem' has a strong stress on the first syllable.
- The odd one out: 'problem'
4. A. damage: ˈdæmɪʤ, B. destroy: dɪˈstrɔɪ, C. improve: ɪmˈpruv, D. threaten: θˈrɛtən
- The words 'damage', 'destroy', 'improve', and 'threaten' all have different stress patterns, but 'improve' stands out due to the weakly stressed first syllable being 'ɪ' instead of a schwa sound, which 'destroy' also has, but 'destroy' is a compound of 'dis-' (which sounds similar to 'de-') so 'destroy' also starts with a different consonant sound (dɪ) than 'dis-', 'de-', 'destruction' as 'dis-' usually carries the stress of the syllable. Since there is also an alternative pronounciation ˈɪmˈpruːv which has a similar stress pattern to the rest of the words, the odd one out would be 'damage' or 'destroy' could be the odd one out instead depending on whether we use the stress patterns alone, or whether we analyze the rest of the words.
- The odd one out: 'damage'
5. A. temperature: ˈtɛmpərəʧər, B. atmosphere: ˈætməsfɪr, C. activity: ækˈtɪvɪti, D. dangerous: ˈdeɪnʤərəs
- The words 'temperature', 'atmosphere', and 'dangerous' have a strong stress on the first syllable, whereas 'activity' has a strong stress on the second syllable.
- The odd one out: 'activity'
6. A. prevent: prɪˈvɛnt, B. global: ˈgloʊbəl, C. international: ɪnərˈnæʃənɑl, D. national: ˈnæʃənəl
- The words 'global', 'international', and 'national' have a strong stress on the first syllable, whereas 'prevent' has a weakly stressed first syllable.
- The odd one out: 'prevent'
