Step-by-step explanation:
The complete sentence is 'We draw countless numbers of lines.' The subject of this question is related to poetry and the visual impact of lines on the expression of ideas. In poetry, a line is a fundamental unit of meaning and auditory effect. It defines the poet's style and contributes to the rhythm and tone of the poem.
