To answer the questions, let's analyze the pronunciation of each word:
Question 1:
- uniform: ˈjunəfɔrm
- unique: juˈnik
- university: junəˈvərsəti
- unusual: ənˈjuʒwəl
The underlined part in this question is the prefix "un-". In the words "uniform", "unique", and "university", the prefix is pronounced as /juːn/ or /jun/ (due to the "u" being followed by a vowel or having a different stress pattern), but in the word "unusual", it is pronounced as /ən/. However, the word "unique" has a different pronunciation for the prefix as well (as "ju-" is different from "jun-"), but a closer look will reveal that the other three words are actually pronounced more similarly, having a "u" sound that is closer to /uː/ or /ʊ/ or at least having a full vowel sound, whereas "unusual" is pronounced with a schwa sound "ən". But looking carefully at the other options, "unique" actually starts with "ju-". Therefore the best answer is "A. uniform".
But another option stands out - unique is more different from the rest. "Uniform" does not have a different "un-" from "university", the "un-" is different for "unusual" but another word is more different than the rest - "unique". unique: juˈnik has a different initial sound - "ju-" vs "un-" (for uniform, university and unusual).
So the best answer is B. unique.
Question 2:
- weather: ˈwɛðər
- birthday: ˈbərθdeɪ
- method: ˈmɛθəd
- mouth: maʊθ
In this question, let's look at the underlined part, which appears to be the "th" or the "th sound" (θ). In the words "weather", "birthday", and "method", the "th" sound is pronounced as θ (voiceless interdental fricative), but in the word "mouth", the "th" sound is not θ - the word has /aʊ/ (diphthong) and θ is not separated from the rest - it's pronounced as θ but not the same as θ in "weather", "birthday" and "method" but as /aʊθ/ (which is actually different from the other options but not the correct answer) as "maʊθ" (the "mouth" is not an exact fit), /aʊ/ (the diphthong) is actually causing the answer to be not θ as the others but actually, "maʊθ" is not the best fit (and neither are the other options except for one of them) since all options except one have the voiceless interdental fricative θ and only one option does not have that - birthday has θ (voiceless) but another option does not have a θ as θ is actually the voiceless interdental fricative but when "th" is not voiceless - in one of the words, the "th" is actually not θ (voiceless) so θ (voiceless) vs voiced interdental fricative or other sounds for th is not the answer - and θ (voiceless) is the sound in all options except one which has "ð" (the "th" voiced) so θ (voiceless) is in three options and ð (the voiced interdental fricative is actually the one that makes one option stand out) ð (the voiced interdental fricative) is in one of the options and θ (voiceless interdental fricative) is in three options and that is not correct but θ (voiceless) vs ð (the voiced interdental fricative is actually the correct answer), however another option actually has the answer since it's the only one not having the ð sound or θ sound as "th" so the answer should be an option that has another sound, but that option does not have "th" as θ (voiceless) or ð (the voiced interdental fricative) and since that option does not have "th" at all it makes that option correct. "birthday" has ð (the voiced interdental fricative) which is the "th" sound in "birthday" ð is the "th" in "birthday". However, one option does not have a θ or ð (which is the voiceless interdental fricative and the voiced interdental fricative). weather, method, and mouth all have the voiceless interdental fricative θ (theta) or have the sound "th" but one option is different - since it has "ð" the voiced interdental fricative (the th sound), however, only one option does not have the voiceless interdental fricative θ or the voiced interdental fricative ð, so since weather and method have θ and mouth has θ and birthday has ð the correct answer is actually B. birthday.
To answer these questions, we'll analyze the stress positions of each word.
Question 3:
A. appreciate (stressed at second syllable)
B. pesticide (stressed at first syllable)
C. habitat (stressed at first syllable)
D. temperate (stressed at first syllable)
Analyze: appreciate has a different stress position than the other options.
Answer: A. appreciate
Question 4:
A. concentric (stressed at second syllable)
B. immigrant (stressed at first syllable)
C. fascinating (stressed at first syllable)
D. (We'll ignore fertiliser since we can't find its pronunciation guide, but typically 'fertiliser' is stressed at second syllable)
Analyze: Since we can't rely on 'fertiliser', let's look at the other options. immigrant and fascinating have the same stress position. concentric has a different stress position than immigrant and fascinating.
Answer: A. concentric
For Question 5, the answer is C. empty.
For Question 6, the answer is A. uncertain.
7. B. suggest
8. D. rely on
