To find the word with the underlined part differing in pronunciation, we will compare the underlined parts in each question.
Question 1: The underlined parts are the beginning of each word. In A (ˈeɪnʧənt), B (ænˈtik), C (ˈpænkeɪk), and D (ˈænsɛstər), all start with a stressed sound. However, the initial sounds in A, C, and D are the same ('eɪn, 'pæn, and 'æns). B has a different initial sound (æn), which is unstressed and different in sound.
Answer: B. antique
Question 2: The underlined parts are the beginning of each word. In A (dɪˈvɛləp), B (dɪˈtərmən), C (ɛnərˈteɪn), and D (ɪnˈkərəʤ), all start with the same initial unstressed sound (dɪ or ɛn/ɪn), but B and A have a similar unstressed 'dɪ'. C (ɛnər) has the same sound but is the most stressed among these (ɛ is different from ɪ in 'dɪ').
However, the closest match to a different underlined part in the beginning of a word would be A and B and C with D. But focusing on the first sound in each word in A, B, and D, it is "dɪ". In C, it is "ɛn", but it is more accurately described as ɛ is different from ɪ, however "ɛn" is closer to ɪn and 'dɪ'. Between 'ɛn' and 'ɪn', 'ɛ' is different from 'ɪ'. Therefore C is different.
Answer: C. entertain
Question 3: The underlined parts are the beginning of each word. In A (ˈlɛftoʊvər), B (loʊˈkeɪʃən), C (ˈoʊvərˈsiz), and D (ɪkˈsplɔr), B has a different initial sound from the rest (loʊ vs. 'lɛft, 'oʊv, ɪk).
Answer: B. location
Question 4: The underlined parts are the beginning of each word. In A (ˈtraɪbəl), B (θˈrɪlɪŋ), C (ˈbrɪljənt), and D (ˈæktɪv), A, C, and D all have a similar sound pattern with a stressed initial sound followed by a short vowel sound. However, B (θˈrɪlɪŋ) and C (ˈbrɪljənt) have a different initial sound from A and D (θ vs. tr and b vs. tr and act). Therefore A is not different from C and D, B and C are. But A is different from B and C, but C and B and A have one distinct feature that is the same. Only one of the options in B and C has a different 'rɪ' and 'lɪ' but is associated with a different underlined part - "br" and "thr". Between "br" and "thr" "thr" is associated with the Greek letter Theta 'θ' (the "th" sound in this, thrilling) 'tr', 'br' and 'act' all have one thing in common: they are made of two distinct sounds (voice and voiceless) sounds. However one of these sounds is the same - between 'tr', 'br' is 'r' and the sounds that 't', 'b' and 'act' are associated with are the voice and voiceless 't'. The option 'act' has a completely different sound in "active". Only one of the options in B has a completely distinct 'θ'. This is associated with B.
Answer: B. thrilling
