Based on the provided IPA notations, here are the answers to the given questions:
1. a. emotion: ˈimoʊʃən
b. indecisive: ɪndɪˈsaɪsɪv
c. obesity: əˈbisəti
d. believable: bəˈlivəbəl
The underlined parts are the first syllables, and the difference is in their sounds and stress patterns. Emotion has a different vowel sound in the first syllable (imoʊʃən), but the difference in stress pattern is the same among all words. Based on this, all four options have the same stress pattern, and the vowel sound is the only variation. But the most obvious difference is with the 'i' sound in 'indecisive.' Based on that, b. indecisive (ɪndɪˈsaɪsɪv) has a unique sound for its underlined part.
2. a. hanging: ˈhæŋɪŋ
b. belong: bɪˈlɔŋ
c. singer: ˈsɪŋər
d. anger: ˈæŋgər
The underlined part is 'ng.' However, the 'ng' in singer is followed by 'ər,' but that is not the only variation since it is the only one that has 'i' followed by 'ng' (ˈsɪŋər). Based on this, c. singer (ˈsɪŋər) has a unique sound for its underlined part.
3. a. behaved: bɪˈheɪvd
b. passed: pæst
c. entertained: ɛnərˈteɪnd
d. changed: ʧeɪnʤd
The underlined part is 'ed' (for the first three words) and 'ed' is sometimes pronounced as a single 'd' or 't' sound. But, in this case, the difference lies in 'passed' as the 'ed' is silent in its pronunciation (pæst), and 'd' in the other three words have different vowel sounds. Based on this, b. passed (pæst) has a unique sound for its underlined part.
4. a. imagination: ɪmæʤəˈneɪʃən
b. average: ˈævərɪʤ
c. language: ˈlæŋgwɪʤ
d. appearance: əˈpɪrəns
The underlined part is 'ge' or 'g.' Based on this, d. appearance (əˈpɪrəns) has a unique sound for its underlined part as it does not have the 'ge' or 'g' sound.
5. a. increase: ˈɪnkris
b. surprise: səˈpraɪz
c. release: riˈlis
d. promise: ˈprɑməs
The underlined part is 'e' followed by different consonant sounds. But in 'release' (riˈlis) and 'promise' (ˈprɑməs), the 'e' is pronounced differently. Based on this, c. release (riˈlis) and d. promise (ˈprɑməs) have unique sounds, but 'release' has a more distinct variation as the 'e' is pronounced as 'i'.
I'll analyze the pronunciation of each word and provide the answer to each question in the format you requested.
**1.**
Analyze:
- 'worthwhile' stressed at first syllable
- 'royal' stressed at first syllable
- 'habit' stressed at first syllable
- 'practice' stressed at first syllable
All four words have the stress on the first syllable.
Answer: This group doesn't provide enough information to answer the question.
**2.**
Analyze:
- 'obese' stressed at second syllable
- 'extend' stressed at second syllable
- 'remote' stressed at second syllable
Since 'dogsled' cannot be found in the dictionary, we cannot determine its stress position.
However, if we consider only the other three words, they all have the stress on the second syllable.
If 'dogsled' were stressed at the first syllable, it would be the word with the main stress placed differently.
However, without the information on 'dogsled', this question cannot be answered.
**3.**
Analyze:
- 'household' stressed at first syllable
- 'Arctic' stressed at first syllable
- 'diet' stressed at first syllable
- 'suppose' stressed at second syllable
Therefore, 'suppose' has a different stress position to other words.
Answer: b. suppose
**4.**
Analyze:
- 'transformation' stressed at third syllable
- 'independence' stressed at third syllable
- 'understanding' stressed at third syllable
- 'illiterate' stressed at second syllable
Therefore, 'illiterate' has a different stress position to other words.
Answer: d. illiterate
**5.**
Analyze:
- 'uncontrollable' stressed at third syllable
- 'biological' stressed at third syllable
- 'particularly' stressed at second syllable
- 'seniority' stressed at second syllable
Therefore, the words 'uncontrollable' and 'biological' have a different stress position to other words.
However, if we need to choose only one word, we cannot answer this question.
