To determine which word has a different sound in the part underlined, let's analyze the given options with their corresponding IPA notations.
11. Find the word which has a different sound in the part underlined.
The underlined parts are likely the "ation" in donation and attachment, the "arity" in charity, and the "acter" in character. Based on the IPA notations:
- donation: doʊˈneɪʃən (sound of "ation" is /eɪʃən/)
- charity: ˈʧɛrɪti (sound of "arity" is /ɛrɪti/, with a short 'e' sound, not matching the "ation" sound)
- attachment: əˈtæʧmənt (sound of "ment" is /mənt/, not "ation" sound; however, the main focus is the sound change for the "ation" group, thus we look for "ation")
- character: ˈkɛrɪktər (sound of "acter" is /ɛrɪktər/, with a short 'e' sound, not matching the "ation" sound, but keeping an open mind)
Comparing these, charity has a different sound in the underlined part ("arity" instead of "ation" or similar, however the key difference is how "a" is pronounced), but looking closely at "character" and considering we are finding a different sound, character and charity both have 'er' ending sounds. Still the question seeks a different sound, and 'ation' appears in 2 cases.
However, the greatest difference lies between charity/character and the 2 other options as their sounds in the main endings aren't the same as the sound of the underlined part in "donation" or "attachment". Still focusing on sounds, charity's 'arity' stands out. And between character, and the other options, the charity's ending is least like the rest. We focus on the fact, it's the one which doesn't have an 'eɪʃən' ending sound. So for different, it is 'arity' and the answer is B.
12. Find the word which has a different sound in the part underlined.
The underlined parts are likely the first syllables and "ove" or "uve" parts of the options. Based on the IPA notations:
- improve: ɪmˈpruv (starts with "im-")
- prove: pruv (starts with a "p" sound without a prefix, also "pro" sound differs from the sounds in improve, and is a different vowel sound from move and love)
- move: muv (starts with "mu", not the "i" sound like in improve)
- love: ləv (starts with a softer "l" sound, but still a distinct "u" sound from the others)
Comparing these, improve starts with an "im-" sound which is different from the other options which start with single sounds ("pro", "mu", "l"). Therefore the answer is A.
