Based on the IPA notation provided, let's analyze the pronunciation of each word:
Question 1:
A. achieved: əˈʧivd ( stress on the second syllable, but the vowel sound in the underlined part "ie" is /iː/ )
B. advanced: ədˈvænst ( stress on the second syllable, but the vowel sound in the underlined part "an" is /æ/ )
C. required: rikˈwaɪərd ( stress on the second syllable, but the vowel sound in the underlined part "ui" is /aɪ/ )
D. replied: rɪˈplaɪd ( stress on the second syllable, but the vowel sound in the underlined part "ie" is /aɪ/ )
The underlined part that differs in pronunciation from the other three is "ie" in achieved, which is pronounced as /iː/. The other three words have different vowel sounds in their underlined parts.
Answer: A
Question 2:
A. explanation: ɛkspləˈneɪʃən ( stress on the third syllable, but the vowel sound in the underlined part "ex" is /ɛks/ )
B. experience: ɪkˈspɪriəns ( stress on the second syllable, but the vowel sound in the underlined part "ex" is /ɪk/ )
C. existence: ɪgˈzɪstəns ( stress on the second syllable, but the vowel sound in the underlined part "ex" is /ɪg/ )
D. exciting: ɪkˈsaɪtɪŋ ( stress on the second syllable, but the vowel sound in the underlined part "ex" is /ɪk/ )
The underlined part that differs in pronunciation from the other three is "ex" in explanation, which is pronounced as /ɛks/. The other three words have different vowel sounds in their underlined parts, but the closest to explanation is experience.
However, in the question, we are asked to find the underlined part that differs from the other three in pronunciation. All the underlined parts "ex" are different, but only one can be the answer. The one that is the most different in pronunciation is explanation, which is pronounced as /ɛks/, while the others are pronounced with a short "i" sound /ɪ/.
Answer: A
Question 3:
A. wicked: ˈwɪkəd ( stress on the first syllable, and the vowel sound in the underlined part is /ɪ/ )
B. watched: wɔʧt ( the vowel sound in the underlined part is /ɔ/ )
C. helped: hɛlpt ( the vowel sound in the underlined part is /ɛ/ )
D. worked: wərkt ( the vowel sound in the underlined part is /ə/ )
All the underlined parts differ in pronunciation from each other, but the most different from the other three is watched, which is pronounced with the vowel sound /ɔ/. The other three words are pronounced with different vowel sounds (/ɪ/, /ɛ/, and /ə/).
Answer: B
**Question 4**
Analyze:
'imperial' stressed at second syllable
'simplicity' stressed at second syllable
Since 'magnificence' isn't found in the dictionary, it is impossible to know its stress pattern, thus 'magnificence' will be ignored.

Therefore, 'stimulating' has a different stress position to other words.
Answer: D. stimulating
**Question 5**
Analyze:
'destination' stressed at third syllable
'derivative' stressed at second syllable
'affordable' stressed at second syllable
'ingredient' stressed at second syllable
Therefore, 'destination' has a different stress position to other words.
