Q.DPoem appreciation If one should come too close to earth The atmosphere will shake, With shock wave reaching to the ground Causing the land to quake. 1. Pick out the rhyming words. 2. Mention the rhyme scheme of the stanza. 3. When you read the poem aloud, you can feel/hear a rhythm. What according to you gives rhythm to the poem- the rhyme or the words in a line? Support your answer with examples from the poem.v
Answer:1. 'shake' and 'quake' are the rhyming words. 2. Rhyme scheme: A B C B (lines 2 and 4 rhyme — ABCB). 3. The rhythm mainly comes from the words/metrical pattern (stressed and unstressed syllables) in the lines; rhyme adds musicality. Example: 'With shock wave reaching to the ground' has a steady beat from its word stresses; 'shake'/'quake' provide end-rhyme but the line rhythms create the poem's pulse.
5E2 questions
Q.E1Answer the following questions in about 80-100 words. 1. Narrate how the poet describes the comet.v
Answer:The poet describes the comet as a relentless, fast-moving spectacle that races through the heavens 'day or night' without stopping. He compares its speed to a cheetah and its mass and force to a mountain—both powerful and awe-inspiring. The comet carries a long tail of vapour and dust formed as its outer ice melts; this trail may deposit chemicals on Earth. A close comet could shake the atmosphere and send shock waves to the ground. Regardless of scientific debate, the poet insists that a comet in full flight is the finest spectacle.
Q.E2Answer the following questions in about 80-100 words. 2. Give a detailed account of the various effects caused by the comet to the earth.v
Answer:The poem suggests several possible effects of a comet passing near Earth. As a comet's outer ice melts it produces vapour and dust that trail behind; scientists propose such dust could deliver chemicals that helped start life on Earth. If a comet comes very close, its passage can disturb the atmosphere, producing shock waves that travel to the ground and cause the land to quake. In extreme cases, comet impacts could cause widespread destruction, but the poem focuses on atmospheric shaking, shock waves, and the potential for comet-borne materials to seed life.
