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).

A stain is an unwanted mark of discolouration on a fabric caused due to contact with another substance which cannot be removed by the normal washing process. Stains can be grouped on the basis of their origin, e.g. tea, coffee and fruits come from vegetable source. Stains from shoe polish, tar, oil paints come under grease stains. Animal stains comprise of stains formed by milk, blood and eggs, whereas marks on your clothes after sitting on an iron bench are those of rust and come under mineral stains. Then there are stains that are formed due to dye, into perspiration which can be categorised under miscellaneous stains. Read the given passage and complete the table. Suggest a suitable title.
