Here are the correct answers:
31. A. some
32. B. therefore
33. B. with
34. C. such
35. C. essential
Here are the answers with the options that need correction:
Question 36: C. long-distance (Television is used for mass communication, not long-distance communication. It should be "mass communication" instead.)
Question 37: D. was spoken (The correct verb tense is the present perfect tense. It should be "has been spoken" instead to show the continuation from the past to the present.)
Question 38: C. was coming (The verb tense should be consistent. It should be "was" instead of "was coming" to maintain the past continuous tense. The correct phrase should be "When I was coming home...". However, in the given options, option C seems correct in terms of grammar. But if I had to choose, I'd say C is still correct but a more idiomatic expression would be "on my way home".
To find the word with a different sound in the part underlined, we'll analyze the pronunciation of each word.
**Question 39**
The underlined part is likely the "a" in each word. Let's look at the IPA notations:
* laptop: ˈlæptɑp (the "a" is pronounced as "æ" and "ɑ")
* practice: ˈpræktɪs (the "a" is pronounced as "æ")
* value: ˈvælju (the "a" is pronounced as "æ")
* father: ˈfɑðər (the "a" is pronounced as "ɑ")
The word "father" has a distinct "ɑ" sound, whereas the other words have an "æ" sound. However, "laptop" also has a "ɑ" sound. Considering the options, "father" and "laptop" both have an "ɑ" sound, but "father" is the only one that doesn't have an "æ" sound. This makes it a bit tricky.
**Question 40**
The underlined part is likely the "ed" in each word. Let's look at the IPA notations:
* helped: hɛlpt (the "ed" is pronounced as "t")
* played: pleɪd (the "ed" is pronounced as "d")
* washed: wɑʃt (the "ed" is pronounced as "t")
* finished: ˈfɪnɪʃt (the "ed" is pronounced as "t" and also part of "ʃt")
The word "played" has a distinct "d" sound, whereas the other words have a "t" sound.
**Answer**
Question 39: C and D (both are distinct, however, based on the IPA notation alone, it would be C value and D father have different sounds)
Question 40: B (played)
