To determine which words have underlined parts that differ from the other three in pronunciation, let's examine the given words and their IPA notations. **Question 1. A. develop B. device C. lend D. invent** Looking at the IPA notations: - develop: dɪˈvɛləp - device: dɪˈvaɪs - lend: lɛnd - invent: ɪnˈvɛnt All words but "lend" have the stress on the second syllable (indicated by the ˈ symbol). "Lend" has no stress symbol in its IPA notation, indicating a different stress pattern compared to the other options. The underlined part that differs in pronunciation is actually related to the stress pattern, but more specifically, "lend" has a different ending sound (the "nd" sound in "lend" versus the ending sounds in the other options). However, the primary difference is in the stress and the absence of a distinct vowel sound following the consonant cluster in "lend" compared to the others. Considering the absence of distinct vowel sounds and the differing syllable stress, "lend" stands out. **Question 2. A. message B. luggage C. cottage D. hospitable** Looking at the IPA notations: - message: ˈmɛsɪʤ - luggage: ˈləgɪʤ - cottage: ˈkɑtɪʤ - hospitable: ˈhɑˈspɪtəbəl The first three options ("message", "luggage", "cottage") end with the "ɪʤ" sound, which is not the case for "hospitable". "Hospitable" does not end with the "ɪʤ" sound but instead has a different sequence of sounds following the stressed syllable. Therefore, the word whose underlined part differs from the other three in pronunciation is "hospitable" due to its distinct ending and stress pattern. The answers are: 1. C. lend 2. D. hospitable Analyze: 'worship' stressed at first syllable 'belong' stressed at second syllable 'enjoy' stressed at second syllable 'behave' stressed at second syllable Therefore, 'worship' has a different stress position to other words. Answer: A. worship Analyze: 'harmful' stressed at first syllable 'slowly' stressed at first syllable 'cloudy' stressed at first syllable 'unique' stressed at second syllable Therefore, 'unique' has a different stress position to other words.
