To answer these questions, we need to compare the pronunciation of each word and find the one that differs from the others in terms of stress patterns and vowel sounds. Here are the analyses: Question 1: - risk: rɪsk (main stress is on the only syllable) - campfire: ˈkæmpfaɪər (main stress is on the first syllable) - diverse: dɪˈvərs (main stress is on the second syllable) - admire: ædˈmaɪr (main stress is on the second syllable) Since 'risk' has only one syllable, it has no syllable to shift stress to the second syllable. However, the more crucial aspect here would be that while 'campfire' has stress on the first syllable, all other words have their stress on the second syllable but the one that really stands out is that "risk" is the only word with a single syllable that receives the main stress. Question 2: - resident: ˈrɛzɪdənt (main stress is on the first syllable) - ecosystem: ˈikoʊsɪstəm (main stress is on the first syllable) - release: riˈlis (main stress is on the second syllable) - species: ˈspiʃiz (main stress is on the first syllable) The one that stands out here is 'release', as it's the only word with the main stress on the second syllable, while the others have their main stress on the first syllable. So the answers are: Question 1: A. risk Question 2: C. release I'll analyze each question and provide the answer. **Question 3** Analyze: 'customer' stressed at first syllable 'advantage' stressed at second syllable 'decorate' stressed at first syllable 'homemaker' stressed at first syllable Therefore, 'advantage' has a different stress position to other words.
