Solution
The correct answer is option 3. The communication problem in paragraph 2 directly relates to the opening question of whether electronic music qualifies as music at all. Paragraph 2 states that composers in this medium employ "a new language of forms" with unfamiliar terms that substitute for traditional concepts, creating a barrier for the listener. However, the paragraph concludes that "when the new structural procedures of electronic music are at last fully understood by the listener the barriers between him and the work he faces will be removed." Option 3 captures both sides of this relationship: the unfamiliar forms and terms can obstruct our recognition of electronic music as music, but the obstacle is not permanent.
Option 1 is wrong (reversed). The passage never suggests that difficulty of understanding is what qualifies something as music. The communication problem is presented as an obstacle to acceptance, not as a validating criterion.
Option 2 is wrong (misreads the passage). The communication problem is explicitly tied to the question of whether electronic music counts as music, since the unfamiliar language of forms impedes the listener's sympathetic response. The two discussions are clearly connected, not separate.
Option 4 is wrong (extreme). While it correctly identifies the unfamiliar language and novel terms as a barrier, it overstates the consequence by claiming we "cannot" see electronic music as music. The passage explicitly says these barriers will be removed once listeners understand the new structural procedures, so the impediment is temporary, not absolute.
