Question

[107]. Read the following passage carefully and answer the question.

Passage: Music feels like pure feeling, yet it rests on mathematics. An octave is a doubling of frequency: a note vibrating twice as fast sounds the same note, only higher. Simple ratios govern harmony: a fifth corresponds to a ratio of three to two, a fourth to four to three, and our ears hear these ratios as pleasant and stable. Rhythm is counting in time, with beats divided into halves, thirds and quarters, and a composer who breaks a pattern creates surprise precisely because the listener expected the next beat. This does not make music cold. Knowing the mathematics behind a melody is like knowing the grammar behind a poem: it explains why a phrase moves us, without replacing the feeling itself.

1.
An octave is a doubling of frequency: a note vibrating twice as fast sounds the same note, only higher.
2.
Early maps sometimes filled unknown lands with pictures of monsters and guessed at coastlines.

Cooled lava breaks down over centuries into rich, fertile soil that farmers prize.
4.
Keepers cleaned the great lens, trimmed the wick and watched through the night that the lamp never went out.
