<Questions> 

  1. In the 13 th Century, Genghis Khan was expanding his Mongol Empire and became almost unstoppable, but there was one obstacle that he couldn’t overcome. What was it?

 

 

  1. Write “T” if the statement is true and “F” if the statement is false.
  1. For many years, people in the Karakoran and Himalayan mountain ranges have been growing glaciers.                 
  2. The Mongol Empire made towering walls of ice to protect their empire.                 
  3. People in the Mongol Empire grow glaciers for drinking water and irrigation for their crops.                 

 

 

  1. There are some differences between glaciers that grow in the wild and glaciers that are artificially created. Fill in the blanks.
  1. [glaciers that grow in the wild]
  • Glaciers require three conditions to grow.
    Condition 1: (1)                         
    → A great deal of (2)                          accumulates.
    Condition 2: (3)                                           (2 words) 
    → It then ensures that the stacked up snow persists throughout all (4)                       seasons.
    Condition 3: (5)                         
    → Over the following years, decades, and centuries, the (6)                          of the accumulated snow transforms layers into highly compacted glacial ice.
  1. [glaciers that are artificially created]
  • They are completely (7)                          from wild glaciers.
  • At the confluence of three great mountain ranges, the Himalayas, Karakoran, and Hindu Kush, some local cultures have believed for centuries that glaciers are (8)                          .
    → People have believed certain glaciers can have different (9)                          .
  1. Local glacier growers ‘breed’ new glaciers by grafting together, or (10)                          , fragments of ice from male and female glaciers.
  2. They cover them with charcoal, wheat husks, cloths, or willow branches so they can reproduce.
  3. They grow each year with additional (11)                          , and they transform into fully active glaciers.
  • Farmers use them to irrigate their crops.

 

  1. Which of the following statements is true?
  1. Ladakh receives a lot of rain every year.
  2. People in Ladakh started growing their own glaciers.
  3. Ladakh is located in southern India.
  4. People in Ladakh are not worried about climate change because they know some ways to secure water.

 

  1. The speaker describes horizontal glaciers and vertical glaciers. Fill in the blanks.
  1. [horizontal glaciers]
    • Farmers redirect glacier (1)                          into channels and pipes, then they carefully siphon it off into a series of basins.
    • Villagers control the (2)                          of water into these reservoirs, waiting for each new layer to (3)                          before filling the basin with another wave.
    • In early spring, these frozen pools begin to (4)                          , providing water for irrigation.
  2.  
  3. [vertical glaciers]
    • People use the meltwater from already exciting glaciers (5)                                         (2 words) their villages.
    1. The meltwater enters channels that run downhill
    2. It flows until it reaches a crop site where it bursts forth from a pipe pointing
      (6)                          into the air.
    3. During winter, the temperatures dip and the water (7)                          and forms a 50 meter ice sculpture called (8)                          , shaped like an upside-down ice cream cone.
      → This form minimizes the amount of (9)                                              (2 words) exposed to the sun in the spring and summer, which ensures enough water to feed the farmers’ crops.

 

  1. Which of the following statements is not mentioned in the speech?
  1. Many regions beyond Ladakh started growing their own glaciers.
  2. More than 100 villages in Pakistan, Kazakhstan, and Kyrgyzstan are interested in growing glaciers.
  3. Swiss people created their first stupa in 2016.
  4. In the future, we may once again create glacial walls to protect our territories from invasion.

  3. [vertical glaciers]
    • People use the meltwater from already exciting glaciers (5)  high above   (2 words) their villages.
    1. The meltwater enters channels that run downhill
