The correct answer is A: The bottles are filled again after being returned, collected and washed.
To determine which word has an underlined part that differs from the other three in pronunciation, we need to compare the IPA notations.
Question 6:
The words "recognize", "activate", "navigate", and "substitute" all end with different suffixes.
- recognize: ˈrɛkəgnaɪz (ends with /aɪz/)
- activate: ˈæktəveɪt (ends with /eɪt/)
- navigate: ˈnævəgeɪt (ends with /eɪt/)
- substitute: ˈsəbstətut (ends with /tut/)
Since "recognize" has a distinct ending sound /aɪz/ and "substitute" has a distinct sound in its suffix /tut/, while "activate" and "navigate" have similar sounds /eɪt/, we can conclude that "substitute" has an underlined part that differs from the other three in pronunciation. However, this conclusion does not align with the multiple-choice format given in the question. We should compare the first part of each word instead.
- recognize: ˈrɛkəgnaɪz (starts with /rɛk/)
- activate: ˈæktəveɪt (starts with /ækt/)
- navigate: ˈnævəgeɪt (starts with /næv/)
- substitute: ˈsəbstətut (starts with /səb/)
Considering the starting sounds, "recognize" has /rɛk/, "activate" and "navigate" have similar sounds /ækt/ and /næv/, while "substitute" has /səb/. In this case, all four options are different in their starting sounds. To provide a correct answer according to the question's requirement, the most reasonable choice would be the one with a completely distinct sound, which could be any of the options.
Question 7:
The words "thin", "those", "think", and "thanks" have the following IPA notations:
- thin: θɪn
- those: ðoʊz
- think: θɪŋk
- thanks: θæŋks
Comparing the starting sounds:
- thin: θɪn (starts with /θɪn/, voiceless interdental fricative)
- those: ðoʊz (starts with /ðoʊz/, voiced interdental fricative)
- think: θɪŋk (starts with /θɪŋk/, voiceless interdental fricative)
- thanks: θæŋks (starts with /θæŋks/, voiceless interdental fricative)
The word "those" starts with a voiced interdental fricative /ð/, while the other three words start with a voiceless interdental fricative /θ/. Therefore, the correct answer is:
Question 7: B. those
Here are the answers to the multiple-choice questions:
8. A. as if
9. C. so quickly
10. A. would have been
11. D. put up with
12. A. hadn't stolen
13. C. practice
