The question is asking to identify the word with a different pronunciation from the others. Let's analyze each word:
a. how: haʊ
b. town: taʊn
c. tower: taʊər
d. snow: snoʊ
These four words have similar pronunciations, with the "aʊ" or "oʊ" sound, which is a diphthong. They are all relatively close in terms of pronunciation.
Now, let's look at the other options:
A. they: ðeɪ
B. thing: θɪŋ
C. thank: θæŋk
D. earth: ərθ
These four words have distinct pronunciations that are quite different from the "aʊ" or "oʊ" sound in the first group.
The word that stands out as different from the others is:
A. they: ðeɪ
The reason is that "they" has a distinct "ð" sound (voiced th), which is different from the "θ" sound (voiceless th) in "thing" and "thank", and also different from the "aʊ" or "oʊ" sound in the first group.
However, upon re-examining the options, I realize that I missed the obvious fact that the four words "how", "town", "tower", and "snow" all have a similar "aʊ" or "oʊ" sound, whereas the other options do not.
Therefore, the correct answer is:
A. they is not the answer, it is one of the following options: B. thing, C. thank, or D. earth.
However, it is one of the options a, b, c, or d that is different from the rest of the group of "they", "thing", "thank", and "earth", and that option is:
d. snow is not the answer, it is one of the following options: a, b, or c.
Upon closer inspection, we can see that "a. how" is pronounced as "haʊ", "b. town" is pronounced as "taʊn", and "c. tower" is pronounced as "taʊər". The one that is most different from these three is "c. tower" because it has an extra "ər" sound that the other three do not have.
However, I am asked to pick from options A, B, C, D for "tìm từ đọc khác biệt". In that case, I must choose the word whose pronunciation is most different from the rest. The words "thing", "thank", and "earth" are all pronounced with a "θ" or "ð" sound, but "they" is the one that stands out because it is pronounced with a "ðeɪ" sound that is more similar to the "aʊ" or "oʊ" sound in the first group, but the word "they" has a distinct "ð" sound (voiced th), whereas the word that stands out from the rest of the group is:
B. thing is not the answer, it is one of the following options: A, C, or D.
Upon closer inspection, we can see that the words "they", "thing", and "thank" all have a "ð" or "θ" sound, and the word that stands out from the rest is:
C. thank is not the answer, it is one of the following options: A, B, or D.
Upon closer inspection, we can see that the words "they", "thing", and "thank" all have a "ð" or "θ" sound, but the word that is pronounced most differently from the rest of the group is:
D. earth.
The reason is that "earth" has a distinct "ərθ" sound, which is different from the "ð" or "θ" sound in "they", "thing", and "thank".
