To answer the questions, let's analyze the pronunciation of each word.
Question 1: A. decrease B. expand C. concern D. reliable
The words "decrease", "concern", and "reliable" have the stress on the first syllable (ˈdikris, kənˈsərn, and rɪˈlaɪəbəl). In contrast, the word "expand" has the stress on the second syllable (ɪkˈspænd). Therefore, the correct answer is B. expand.
Question 2: A. gradual B. building C. product D. crowded
The words "building", "product", and "crowded" have the stress on the first syllable (ˈbɪldɪŋ, ˈprɑdəkt, and ˈkraʊdɪd). In contrast, the word "gradual" also has the stress on the first syllable (ˈgræʤuəl). At first glance, it seems that they are all the same. However, the second syllable of "gradual" is "du", while the second syllable of the other three options is a single vowel sound. This difference is more nuanced and relates to syllable division. However, if we focus on the general syllable stress, we would say they are all the same. But if we look closely, the vowel sound of the first syllable of the words is also slightly different. In particular, the vowel sound in the first syllable of the word "gradual" is /æ/, while the vowel sound in the first syllable of the word "building" is /ɪ/, and the vowel sound in the first syllable of the words "product" and "crowded" is /raʊ/. So in terms of vowel sound, the answer is A. gradual, B. building, or C. product, or D. crowded. However, if we had to choose one, we could say that the vowel sound /æ/ in the word "gradual" is different from the other options, and the other options are closer to each other in terms of the first syllable sound (/ɪ/, /pr/, and /kr/). However, among the three options B, C, D, we could also say that the vowel sound /ɪ/ is different from /raʊ/. So it would be more reasonable to say that the correct answer is B. building.
Therefore, the answers to the questions are B. expand and B. building.
