In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. B: Earthquakes, volcanic eruptions and other underwater explosion above or below water all have the potential to generate a tsunami. C: Unlike normal ocean waves, which are generated by wind, or tides, which are generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water. D: Thus, tsunami can not be attributed to gravitational pull of the moon or the sun.
Given below are six sentences, four of which, are jumbled. Pick the option that gives the correct order. Sentence 1. At least 370 residents of the islands of Java and Sumatra were killed on Saturday when a sudden tsunami struck the coastline. P. While Indonesia has tsunami-detection buoys positioned off its coastlines, they have not functioned for six years. Q. An eruption of the volcano Anak Krakatau set off an underwater landslide at 2130 hours local time Saturday, triggering a giant tsunami. R. But given the landslide’s proximity to inhabited areas, an early-warning system may not have affected the outcome, according to experts. S. Anak Krakatau, is located at the entrance to the Sunda Strait, about 20 nm from the nearest populated shores. Sentence 6. In addition to the rising death toll, more than 1450 were injured in the disaster, and another 130 remain missing.
Which of the following statements is correct about the tsunami? 1. The term Tsunami comes from the Korean word “tsu” meaning harbour and “name” meaning wave. 2. Tsunami has a much smaller amplitude (wavelength) offshore and a very strong wavelength at sea.
