    The trade winds are the surface component of the Hadley Cell. At the horse latitudes, dry air descends from the upper atmosphere, creating a zone of high pressure. This air then rushes toward the heat-induced low pressure at the equator. As it travels, the Earth’s rotation deflects the wind—to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This creates a remarkably consistent wind pattern that stays between 30° latitude and the equator. Historically, these winds were the “engine” for sailing ships, providing a reliable path for transatlantic commerce.

    Rift valleys are significant geographical features representing a nascent divergent plate boundary. In East Africa, tensional forces are pulling the lithosphere apart, causing the crust to thin and fracture. This process, known as rifting, leads to the vertical displacement of rock blocks. The subsided block or Graben, forms the valley floor, while the uplifted sides form steep escarpments or Horsts. This region is a hotbed of tectonic and volcanic activity and is geologically significant as it may eventually lead to the formation of a new ocean basin, similar to how the Red Sea was formed millions of years ago.

    Alauddin Khalji firmly opposed the interference of the ulama—religious scholars—in state matters. He believed that governance should be based on political necessity rather than religious dictates. His strong and independent approach helped him maintain absolute royal authority. Alauddin openly stated that the state’s laws (zawabit) could differ from religious laws (sharia) because a king’s primary duty was to ensure stability, security and prosperity. By limiting the influence of the ulama, he strengthened administrative efficiency and military reforms. This separation of religion from governance allowed him to implement bold policies, including revenue reforms and strict law-and-order measures.

  4. The five lockers that are toggled exactly twice are locker numbers 2, 3, 5, 7 and 11. These are prime numbers and have exactly two distinct factors—1 and themselves. This means they are toggled only by person 1 and one other person (themselves), resulting in exactly two toggles. Khoisnam uses this kRead more

    The five lockers that are toggled exactly twice are locker numbers 2, 3, 5, 7 and 11. These are prime numbers and have exactly two distinct factors—1 and themselves. This means they are toggled only by person 1 and one other person (themselves), resulting in exactly two toggles. Khoisnam uses this knowledge to extract the code clue from these specific lockers that were touched only twice during the puzzle.
