Based on the provided IPA notations, I will analyze the pronunciation of each word and find the one whose underlined part differs from the other three.
1. A. invented: ɪnˈvɛntɪd
B. messaged: * (no IPA notation provided, but the verb "messaged" is often pronounced as /ˈmɛsɪdʒd/)
C. ploughed: plaʊd
D. trained: treɪnd
The underlined part in these words is the "ed" ending. The pronunciation of the "ed" ending is usually /ɪd/ or /d/. However, the word "ploughed" has a different pronunciation, with the "ough" part pronounced as /aʊ/. Therefore, the answer is C.
However, since we don't have the IPA notation for "messaged", let's look at the other option. In this case, we should consider the "ed" sound, and the IPA notations for "invented", "ploughed", and "trained" all show the "ed" ending with a distinct sound. "invented" ends with "tɪd", "ploughed" ends with "d", and "trained" ends with "nd", but none of these match the usual "ed" sound in verbs, which is usually /ɪd/ or /d/. But "trained" has a different sound, its "ai" part is pronounced as "eɪ" which is different from the "e" sound in "invented" and "ploughed", however it's the "ed" sound that's being considered.
A better answer for this question would be "messaged" if its IPA notation was provided, since "messaged" is a verb and has a different sound, or "invented", as it has a "tɪd" ending, whereas the others have a "d" or "nd" ending.
2. A. guitar: gɪˈtɑr
B. cruel: kruəl
C. truth: truθ
D. flute: flut
The underlined part in these words is the vowel sound in each word. The words "guitar", "cruel", and "truth" all have a distinct vowel sound, but "flute" has a different vowel sound compared to the others. However, "guitar" and "cruel" both have vowel sounds (ɪ and uə) with a distinct sound, whereas "truth" has a "u" sound (u) which sounds like "u" in "cruel" and unlike "ɪ" in "guitar". "flute" has a "u" sound but its sound is more similar to the "u" sound in "truth" and "cruel", however it's a different "u" sound (uː is a longer sound, which isn't present in this word). And the vowel sound "ɪ" in "guitar" is different from "u" sounds in "cruel", "truth", and "flute". But the sound of "u" in "cruel" and "truth" is similar.
However, a better answer would be "guitar" as it has an "ɪ" sound, whereas the others have "u" sounds, although "u" in "cruel" is different, but "guitar" is more different from the others.
The answers are A and A.
