To answer these questions, we need to analyze the pronunciation of each word.
1. Question 1: A. compete B. scenery C. express D. complete
We can see that in "compete" and "complete", the stress is on the second syllable (kəmˈpit and kəmˈplit).
The word "express" also has the stress on the second syllable (ɪkˈsprɛs).
In contrast, the stress in "scenery" is on the first syllable (ˈsinəri).
However, if we look closer, the underlined parts in "compete" and "complete" are "pet" and "plet", and they differ in pronunciation from the other two in terms of their ending sounds (/pet/ vs /plet/ and /sprɛs/).
So the underlined parts of "scenery" (which has an ending sound of /əri/) and "express" (/sprɛs/) are more similar.
Hence the word whose underlined part differs from the other three in pronunciation is "scenery" (B), because the ending sound /əri/ is more different from /pet/, /plet/, and /sprɛs/.
2. Question 2: A. checkout B. chef C. challenging D. charity
We can see that in "checkout", "challenging", and "charity", the "ch" sound is /ʧ/ (a voiceless postalveolar affricate, like the "ch" in the word "church").
However, in the word "chef", the "ch" sound is /ʃ/ (a voiceless postalveolar fricative, like the "sh" in the word "shoe").
Hence the word whose underlined part differs from the other three in pronunciation is "chef" (B), because the "ch" sound /ʃ/ differs from the "ch" sound /ʧ/ in the other three words.
Analyze:
'determine' stressed at second syllable
'celebrate' stressed at first syllable
'advertise' stressed at first syllable
'animate' stressed at first syllable
Therefore, 'determine' has a different stress position to other words.
Answer: A. determine
B. discounts
