For Question 1, the correct answer is C. contribution.
For Question 2, the correct answer is B. started.
To answer these questions, I'll analyze the pronunciation of each word and find the one that's pronounced differently from the others in each group.
**Question 3: A. appeared B. escaped C. emptied D. borrowed**
* appeared: əˈpɪrd (stress on second syllable)
* escaped: ɪˈskeɪpt (stress on second syllable)
* emptied: ˈɛmtid (stress on first syllable)
* borrowed: ˈbɑroʊd (stress on first syllable)
The words "appeared" and "escaped" have a different stress pattern than "emptied" and "borrowed". However, "appeared" and "escaped" also have a different vowel sound in their first syllable compared to "emptied" and "borrowed". But if we compare the vowel sound of "escaped" and "appeared", they both start with a different vowel sound (/ɪ/ and /ə/ respectively) while the other two words start with a distinct vowel sound (/ɛ/ and /bɑ/ respectively) but both have two syllables stressed like "escaped". Therefore, "emptied" and "borrowed" are not the answer. Since "appeared" and "escaped" both have a different vowel sound compared to the standard, the answer should be one of these two words. In these two words, the difference of pronunciation between them is /ɪ/ in "escaped" and /ə/ in "appeared". The sound /ə/ is not distinct as the other three words (this is the schwa sound), so "appeared" is more similar to "emptied" and "borrowed". So the answer is "escaped".
**Question 4: A. introduce B. grocery C. customer D. wisdom**
* introduce: ɪntrəˈdus (starts with /ɪn/)
* grocery: ˈgroʊsəri (starts with /ˈgroʊ/)
* customer: ˈkəstəmər (starts with /ˈkə/)
* wisdom: ˈwɪzdəm (starts with /ˈwɪz/)
All the words start with different sounds. However, three of them start with a /ˈ/ sound (a distinct syllable) while "introduce" does not start with this sound (/ɪn/ is a distinct sound, but it is not as strong as the /ˈ/ sound), so the answer is "introduce".
**Question 5: A. water B. wireless C. tower D. weather**
* water: ˈwɔtər (starts with /ˈwɔ/)
* wireless: ˈwaɪrlɪs (starts with /ˈwaɪ/)
* tower: taʊər (starts with /taʊ/)
* weather: ˈwɛðər (starts with /ˈwɛ/)
Three of the words start with a /ˈw/ sound while "tower" starts with a /taʊ/ sound. So the answer is "tower".
