Answers with explanations
- 27. D
The summary discusses Mehrabian's influential study comparing aspects of verbal and non-verbal communication. Paragraph 4 explicitly discusses assessing the 'effects' of these changes, matching Option D (effects).
- 28. G
The text states subjects were asked to identify 'emotions'. Mehrabian himself later says his findings dealt with 'feelings and attitudes'. This corresponds directly to Option G (feelings).
- 29. A
The summary notes the first experiment focused on voice tones and a second area. The text says subjects were shown 'photos of female faces', identifying facial expression as the other key area. This matches Option A (facial expressions).
- 30. E
For the second experiment, subjects listened to recorded words. The text explicitly divides these into words with positive, neutral, and negative 'meanings'. Thus, it focused on voice tone and 'word meanings', which is Option E.
- 31. YES
The statement claims a limitation was having too few subjects. Paragraph 3 lists limitations, beginning with 'The first is that the entire study involved only 62 subjects,' indicating this low number was indeed a flaw. Therefore, the answer is YES.
- 32. NO
The statement claims the subjects' similar background was an advantage. The text states their backgrounds were 'remarkably uniform' and argues this is a limitation, suggesting the findings might merely be a 'product of the nature of the sample'. Because the writer views this as a flaw, not an advantage, the answer is NO.
- 33. NOT GIVEN
The statement argues the two experiments should have been carried out in a different order. While the passage heavily criticizes the study's methodology (sample size, use of neutral words), it never mentions or suggests that the sequence of the experiments should have been reversed. Thus, the answer is NOT GIVEN.
- 34. NO
The statement claims the choice of a neutral word was helpful. However, Paragraph 4 argues this was a flaw, stating that because they used a neutral word, subjects 'found little meaning there' and 'it was impossible for the effects of changes in verbal input to be assessed'. Therefore, it was not helpful. The answer is NO.
- 35. NOT GIVEN
The statement claims the study would have been more valid if it had included a range of languages. While the author notes that people 'make extensive use of the multi-faceted vehicle of language' in real contexts, there is no mention that the study should have tested multiple or foreign languages. Thus, the answer is NOT GIVEN.
- 36. A
The question asks what the writer says about 'numerical precision'. The text states that this precision is an 'appealing aspect' of the study, which makes people trust it more. This perfectly aligns with Option A: 'It makes the claims more attractive'.
- 37. B
The writer is concerned that the popularity of the formula encourages people to overestimate non-verbal messages 'compared with the verbal one', implying the verbal message (language) is being incorrectly devalued. This matches Option B (undervaluing of language).
- 38. D
Bradley sarcastically notes that if non-verbal cues were truly 93% of communication, learning language would be a waste of time. The underlying point is that because we *do* make the immense effort to learn language, language must be vitally important. This aligns with Option D.
- 39. A
Mehrabian clarifies that his research only applied to communicating 'feelings and attitudes', and warns it is absurd to apply it to all communication (like abstract relationships). He is restricting his findings to 'only one area of communication', matching Option A.
- 40. C
In this paragraph, the writer outlines three different ways textbook authors handle Mehrabian's formula: being faithful to context, playing down the percentages, and using the numbers blindly. This serves to 'present varying interpretations of Mehrabian's study', matching Option C.
