The correct answer is The mangrove trees do not get uprooted by storms and tides because of their extensive roots.

Key Points

  • Mangroves:
    • Mangroves are a special type of vegetation. And they are found in the intertidal regions where freshwater and saltwater intermixes, in the bays, estuaries, creeks, and lagoons.
    • They are the salt-tolerant variety of plants, which can survive in harsh conditions. And they are economically and ecologically significant.
    • They represent the littoral forest ecosystem.
    • They are also called Halophytes – They are salt-tolerant.
    • The trees that grow in Mangrove Forests are generally 8-20 meters high. These trees have thick leaves.
    • They have blind roots which are called Pneumatophores. These roots help these trees to respire in anaerobic soils. 
    • The seeds of Mangrove Forests trees germinate in the trees themselves before falling – This is called the Viviparity mode of reproduction.
    • According to the Forest Survey of India, 2019, Mangroves’ cover in the country increased by 54 sq km (91.10 per cent) in comparison to the 2017 assessment.
    • The mangrove forests of Sundarbans are the largest mangrove forests in the world. 
    • Mangroves greatly contribute to reducing the loss of life and damage to property from storms and cyclones as they reduce the impacts of waves, storm surges, and high winds. 
    • Mangroves function as a safety hedge as they do not get uprooted by storms and tides because of their extensive roots.
    • Tsunamis are caused by earthquakes and landslides disturbing large masses of water. The resulting tsunami waves can travel rapidly over very long distances across the ocean. As the waves approach land, they increase in height that results in massive destruction and loss of life.
    • Mangroves act as a natural barrier to storms and tsunamis by reducing down the effects of wind and waves and these dense roots help in binding and building soils.

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.

Read the passage carefully and select the best answer to each question out of the given four alternatives.
Public opinion may be passive and false or active and real. It is claimed in theory that all governments are ultimately based on the opinion or sanction of the governed. But we find that in practice the people's rights are often trodden down and tyranny and oppression are allowed to continue. The government does it not because the people want it to do so but because they are too idle, too uneducated and too disunited or timid to oppose the govern ment. Such public opinion is passive and false and not an active verdict. But when we find people alert, intelligent and determined to let the government know their will, when they want to exercise actively their voice in the management of their country, we have an instance of true or active public opinion. True public opinion is formed by and expressed through the press, the platform, political parties and educational institutions. These have sacred duties to perform, duties on which depends the ultimate good of the entire community. The press today wields a tremendous influence, So it should support the causes and move ments and condemn the wrong one's and thus teach people to form correct opinion. A free and fair press ventilates the grievances of the public. Thus a healthy relationship develops between the people and the government through out an unbiased press. Political parties also help to create and regulate opinions. No less important part is played by the educational Institutions which train the minds of the young people who will be the citizens of tomorrow. It has been said that modern Germany and China have been made by their universities. It is necessary that the young and the growing minds should imbibe the spirit of fellow-feeling, the spirit of tolerance, the habit of compromise, and show due regard for the feelings and opinion of others without which a democratic society cannot function, let alone succeed. When there is true awakening of the people, we shall have the real and conscious public opinion. And justice will reign on earth and truly will the voice of the people be the voice of God.
