Accepted Answer

To solve these questions, we need to analyze the pronunciation of each word and identify the underlined part that differs from the other three in pronunciation.

Question 9:
A. achievements 
B. videos 
C. recordings 
D. speakers

Comparing the given IPA notations for each word, we can see that the main stress patterns are the same for B, C, and D (the main stress falls on the first syllable). However, in "achievements" (A), the main stress falls on the second syllable, but the main difference lies in the starting sound. For B, C, and D, the starting sounds are "vɪ" (vi), "rɪ" (ri), and "sp" (spi) respectively, while "achievements" starts with a different sound "ə" (schwa). Yet, the main difference in pronunciation between A and the rest lies in the fact that A is the only word not having the /i/ sound at the beginning of its pronunciation. The starting sounds of "videos", "recordings", and "speakers" all contain the /i/ sound, while "achievements" does not. Therefore, the word whose underlined part differs from the other three in pronunciation is A.

Question 10:
A. musical 
B. eliminate 
C. electrical 
D. appliance

Comparing the given IPA notations for each word, we can see that the main stress patterns are the same for B, C, and D (the main stress falls on the second syllable). However, in "musical" (A), the main stress also falls on the second syllable, so this is not the difference we are looking for. Looking more closely, we can see that the starting sounds for B, C, and D are "ɪ" (i), "ɪ" (i), and "ə" (schwa) respectively. Although the starting sound for "appliance" (D) does not contain the /i/ sound, it is the only word among B, C, and D whose underlined part is different from the rest in terms of the presence or absence of the /i/ sound. However, comparing it with "musical", we see that the main difference lies in the stress pattern of the word. Yet, this is not the main difference. The main difference lies in the starting sound of "musical", "m" sound, as opposed to other options which all start with the vowel sounds.

Analyze: 
&#x27;invention&#x27; stressed at second syllable
&#x27;Internet&#x27; stressed at first syllable
&#x27;generous&#x27; stressed at first syllable
&#x27;driverless&#x27; stressed at first syllable
The stress position of &#x27;invention&#x27; is different from the other three words.

Answer: A. invention

12. C. cleaning
13. D. but
14. D. was listening
15. A. buttons
16. B. invention 
17. B. will open
