To answer the questions, let's analyze the underlined parts of each word and compare their pronunciation:
Question 1:
The underlined parts are the prefixes of each word. The pronunciation of the prefixes is as follows:
- collection: /kəˈlɛkʃən/ (kə-)
- helper: /ˈhɛlpər/ (h-)
- contest: /ˈkɑntɛst/ (kɑn-)
- everyone: /ˈɛvriwən/ (ɛv-)
The prefix "h-" in "helper" is pronounced differently from the others, which all start with a vowel or a vowel sound followed by a consonant.
So the answer to question 1 is B.
Question 2:
The underlined parts are the "augh" or "au" in each word. The pronunciation of these underlined parts is as follows:
- laugh: /læf/ (æ is not a typical sound for the "au" in taught or daughter, and also diphthong "aʊ" is also not present here)
- naughty: /ˈnɔti/ (ɔ is a different vowel sound from the "aʊ" in taught or the "ɔ" in daughter, which does not have the "aʊ" sound of taught either)
- daughter: /ˈdɔtər/ (ɔ does not have the "aʊ" sound of taught)
- taught: /tɔt/ (ɔ has the typical sound for "au" but there's the option "daughter" to consider and taught is more properly spelt for the phonetic "au")
But consider how we represent "au" (e.g. taught) vs the short "o" sound of naughty. So "au" (aʊ, oʊ, ɔː) vs the "au" in "daughter" (ɔ). Laugh (æ, and note absence of u, is absent).
Let's analyze each question:
**Question 3:**
Analyze:
'president' stressed at first syllable
'volunteer' stressed at third syllable
'recommend' stressed at third syllable
'engineer' stressed at first syllable
Therefore, 'volunteer' and 'recommend' have a different stress position to 'president' and 'engineer'.
However, since there are two correct answers, this question has two answers, however we only choose one answer as a correct answer is required:
Answer: B. volunteer
**Question 4:**
Analyze:
'rainfall' stressed at first syllable
'keyboard' stressed at first syllable
'welfare' stressed at first syllable
'exchange' stressed at second syllable
Therefore, 'exchange' has a different stress position to other words.
Answer: D. exchange
Question 5: D. Hungry
