To answer the questions, I will analyze the pronunciation of each word, focusing on the stress patterns. The correct answers will be the words that have a different stress pattern from the others.
Question 13:
The pronunciations are:
A. English: ˈɪŋlɪʃ (stress on the first syllable)
B. classroom: ˈklæsrum (stress on the first syllable)
C. laughter: ˈlæftər (stress on the first syllable)
D. silk: sɪlk (no stress on the first syllable, or equal stress)
The answer is: D. silk (because it has a different stress pattern, with no stress on the first syllable or equal stress).
Question 14:
The pronunciations are:
A. always: ˈɔlwiz (stress on the first syllable)
B. bottle: ˈbɑtəl (stress on the first syllable)
C. shoulder: ˈʃoʊldər (stress on the first syllable)
D. sunlight: ˈsənlaɪt (stress on the first syllable)
Actually, all the options have stress on the first syllable, so we need to look closer.
The answer is: B. bottle (none of the options is different in terms of stress pattern, but looking at the answers for the other questions, we can deduce the pattern for question 14: looking for a word that starts with a stressed syllable but is not alone in this, but in question 13 and 15 one option has a different stress pattern, so we need a word with an unstressed initial syllable for this question to be a bit different from the others, however, it is not the case).
Question 15:
The pronunciations are:
A. letter: ˈlɛtər (stress on the first syllable)
B. classroom: ˈklæsrum (stress on the first syllable)
C. appealing: əˈpilɪŋ (stress on the second syllable)
D. welcome: ˈwɛlkəm (stress on the first syllable)
The answer is: C. appealing (because it has a different stress pattern, with stress on the second syllable).
