To find the goal of the author over the course of the passage, let's analyze the content of the passage and how it relates to the answer options.
Therefore, the correct answer is "defend electronic music from certain common charges."
Step 1: Identify the main concerns discussed in the passage.
At the beginning, the author lists two common doubts about electronic music: whether it is music at all, and whether it is “inhuman”. These are clearly “charges” or objections raised against electronic music.
Step 2: Observe how the author responds to these doubts.
The author explains that:
electronic music uses a new language and new forms, which creates a communication gap, and
despite the machines involved, the human composer is still the one making all the creative decisions (collecting sounds, programming, choosing forms, etc.).
Both points are meant to show that electronic music is understandable as music and is not inhuman.
Step 3: Match this with the options.
Option (1) mentions the difference between modern and nineteenth-century composers. This is referred to, but only as a supporting point, not the main goal.
Option (2) speaks of differentiating between electronic and other music. The author does compare them, but again only to answer the objections.
Option (3) is incorrect, because Lejaren Hiller and Stravinsky are cited as references, not as attackers.
Option (4) correctly captures the overall purpose: the author aims to defend electronic music against the charges that it is not real music and that it is inhuman.
Hence, the best answer is Option (4).
The question revolves around understanding the connection between the "communication problem" discussed in the passage and specific questions posed at the beginning of the passage. Let's break down the question and the relevant segments from the passage:
Step 1: Recall the initial questions mentioned in paragraph 1.
The author reports two common doubts about electronic music:
Is electronic music really music?
Is it “inhuman”?
Step 2: Understand the “communication problem” in paragraph 2.
The author explains that electronic music uses new structures and a “new language of forms” — terms like “densities,” “dynamic serialization,” “permutation,” etc. These unfamiliar concepts make it harder for the listener to understand the music at first.
Step 3: Connect the communication problem with the initial questions.
Because electronic music uses unfamiliar terminology and structures, a listener might initially feel that it is not “music” in the traditional sense. However, the author clearly states that {once the listener understands these new structural procedures, the barriers will be removed}. This means the communication problem is temporary and can be overcome.
Step 4: Match with the options.
Option (1) correctly states that unfamiliar forms and terms can hinder our ability to recognize electronic music as music, but that this obstacle is removable.
Option (2) incorrectly claims that the new language makes understanding impossible. The author says the opposite.
Option (3) is incorrect because the communication problem directly relates to the question “is this music at all?”
Option (4) is incorrect because the author never claims that difficulty is necessary for something to be considered music.
Thus, the best answer is Option (1).
To determine the correct answer to this question about Stravinsky’s description of music, we need to analyze the specific effect or contribution of this description as mentioned in the passage. The task is to identify which of the given options is NOT an outcome of Stravinsky's description.
To solve this question, we need to determine the meaning of the phrase "sui generis" as used in the given comprehension passage. Let's break down the context in which it appears:
With this understanding, let's evaluate the options:
Thus, the correct answer is Particular, as it best describes the unique and distinct nature of the new languages and forms explored in electronic music.
Step 1: Examine the phrase in context.
In paragraph 3, the author says that the serious-minded composer believes that the “aesthetic magic” of electronic music lies in exploring \(\textit{sui generis}\) languages and forms.
Step 2: Understand the contextual meaning.
The context makes it clear that the composer is not simply using familiar musical structures but is deliberately creating or discovering forms that are:
new,
unique,
original,
distinctive to electronic music.
Step 3: Evaluate the options.
(1) Particular — fits well because sui generis means “of its own kind,” “unique,” or “particular to itself.”
(2) Generic — opposite of the intended meaning.
(3) Unaesthetic — the passage describes the forms as aesthetically magical, not unaesthetic.
(4) Indescribable — the passage never suggests they cannot be described; only that they are unique.
Thus, the meaning conveyed is best represented by Option (1).


When people who are talking don’t share the same culture, knowledge, values, and assumptions, mutual understanding can be especially difficult. Such understanding is possible through the negotiation of meaning. To negotiate meaning with someone, you have to become aware of and respect both the differences in your backgrounds and when these differences are important. You need enough diversity of cultural and personal experience to be aware that divergent world views exist and what they might be like. You also need the flexibility in world view, and a generous tolerance for mistakes, as well as a talent for finding the right metaphor to communicate the relevant parts of unshared experiences or to highlight the shared experiences while demphasizing the others. Metaphorical imagination is a crucial skill in creating rapport and in communicating the nature of unshared experience. This skill consists, in large measure, of the ability to bend your world view and adjust the way you categorize your experiences. Problems of mutual understanding are not exotic; they arise in all extended conversations where understanding is important.
When it really counts, meaning is almost never communicated according to the CONDUIT metaphor, that is, where one person transmits a fixed, clear proposition to another by means of expressions in a common language, where both parties have all the relevant common knowledge, assumptions, values, etc. When the chips are down, meaning is negotiated: you slowly figure out what you have in common, what it is safe to talk about, how you can communicate unshared experience or create a shared vision. With enough flexibility in bending your world view and with luck and charity, you may achieve some mutual understanding.
Communication theories based on the CONDUIT metaphor turn from the pathetic to the evil when they are applied indiscriminately on a large scale, say, in government surveillance or computerized files. There, what is most crucial for real understanding is almost never included, and it is assumed that the words in the file have meaning in themselves—disembodied, objective, understandable meaning. When a society lives by the CONDUITmetaphor on a large scale, misunderstanding, persecution, and much worse are the likely products.
Later, I realized that reviewing the history of nuclear physics served another purpose as well: It gave the lie to the naive belief that the physicists could have come together when nuclear fission was discovered (in Nazi Germany!) and agreed to keep the discovery a secret, thereby sparing humanity such a burden. No. Given the development of nuclear physics up to 1938, development that physicists throughout the world pursued in all innocence of any intention of finding the engine of a new weapon of mass destruction—only one of them, the remarkable Hungarian physicist Leo Szilard, took that possibility seriously—the discovery of nuclear fission was inevitable. To stop it, you would have had to stop physics. If German scientists hadn’t made the discovery when they did, French, American, Russian, Italian, or Danish scientists would have done so, almost certainly within days or weeks. They were all working at the same cutting edge, trying to understand the strange results of a simple experiment bombarding uranium with neutrons. Here was no Faustian bargain, as movie directors and other naifs still find it intellectually challenging to imagine. Here was no evil machinery that the noble scientists might hide from the problems and the generals. To the contrary, there was a high insight into how the world works, an energetic reaction, older than the earth, that science had finally devised the instruments and arrangements to coart forth. “Make it seem inevitable,” Louis Pasteur used to advise his students when they prepared to write up their discoveries. But it was. To wish that it might have been ignored or suppressed is barbarous. “Knowledge,” Niels Bohr once noted, “is itself the basis for civilization.” You cannot have the one without the other; the one depends upon the other. Nor can you have only benevolent knowledge; the scientific method doesn’t filter for benevolence. Knowledge has consequences, not always intended, not always comfortable, but always welcome. The earth revolves around the sun, not the sun around the earth. “It is a profound and necessary truth,” Robert Oppenheimer would say, “that the deep things in science are not found because they are useful; they are found because it was possible to find them.”
...Bohr proposed once that the goal of science is not universal truth. Rather, he argued, the modest but relentless goal of science is “the gradual removal of prejudices.” The discovery that the earth revolves around the sun has gradually removed the prejudice that the earth is the center of the universe. The discovery of microbes is gradually removing the prejudice that disease is a punishment from God. The discovery of evolution is gradually removing the prejudice that Homo sapiens is a separate and special creation.
