    This question delves into deep philosophical and existential speculation. The last thought of the last conscious being in the universe before existence ends could encompass various profound themes:

    1. Reflection on Existence: A contemplation on the nature of existence itself—what it meant to be, to live, and to perceive.
    2. Loneliness or Unity: A feeling of ultimate solitude or perhaps a sense of unity with everything that has ever existed.
    3. Gratitude or Regret: A final expression of gratitude for having experienced life or regret for unfinished endeavors or lost opportunities.
    4. Acceptance or Resistance: A thought of acceptance, embracing the end as a natural part of existence, or resistance, a desire for life and consciousness to continue.
    5. Memory or Forgetting: A recollection of memories, the summation of life’s experiences, or the fading away into oblivion, as if even memory itself ceases to hold meaning.
    6. Wonder or Understanding: A profound wonder about the mysteries of the universe or a serene understanding, a moment of ultimate clarity.

    Statement 1 is incorrect because, as per Article 71(2) of the Indian Constitution, the actions performed by a person in the capacity of President or Vice-President remain valid even if their election is declared void by the Supreme Court. Article 71(2) explicitly states that such acts shall not be invalidated due to the court’s declaration. It reads: “If the election of a person as President or Vice-President is declared void by the Supreme Court, acts done by him in the exercise and performance of the powers and duties of the office of President or Vice-President, as the case may be, on or before the date of the decision of the Supreme Court shall not be invalidated by reason of that declaration.”

    Statement 2 is also incorrect. The Constitution of India does not have any provision allowing for the postponement of the Presidential election due to the dissolution of some Legislative Assemblies. The election must be held within the prescribed time, regardless of such dissolutions.

    Statement 3 is incorrect because Article 111 of the Constitution, which outlines the process of granting or withholding assent to bills, does not impose a specific time limit for the President to act on a bill. Article 111 states: “When a Bill has been passed by the Houses of Parliament, it shall be presented to the President, and the President shall declare either that he assents to the Bill, or that he withholds assent therefrom.” There is no mention of a time frame within which the President is required to make this decision. The President may, however, return a non-Money Bill for reconsideration by Parliament, but even here, the Constitution does not set a specific deadline for the President’s assent.

    The question “Why does the universe exist rather than nothing?” is one of the deepest and most profound questions in philosophy, science, and metaphysics. While there is no single agreed-upon answer, various disciplines provide frameworks for exploring the question:

    1. Philosophical Perspectives

    • Contingency and Necessary Existence: The philosopher Leibniz famously posed this question and suggested that there must be a “sufficient reason” for the universe’s existence. He proposed that a necessary being (often equated with God) exists as the ultimate reason for why something exists rather than nothing.

    • Nothingness vs. Something: Some argue that “nothingness” may not actually be a natural state—it might be just as puzzling as “something.” In this view, “something” existing could be more likely or fundamental than the concept of absolute nothingness.

    • Existence as a Brute Fact: Some philosophers argue that the existence of the universe may simply be a “brute fact” that requires no further explanation. It exists, and that’s all there is to it.

    2. Scientific Approaches

    • Quantum Physics: In quantum mechanics, particles can spontaneously appear and disappear due to quantum fluctuations, even in a “vacuum.” This suggests that “nothingness” may be unstable and that something can arise naturally from an apparent void. Physicist Lawrence Krauss discusses this in his book A Universe from Nothing.

    • The Multiverse Hypothesis: Some theories suggest our universe is just one of many in a “multiverse.” If an infinite number of universes arise from underlying processes, the existence of “something” could be inevitable.

    • Cosmological Models: Certain models, like the Big Bang theory, describe how the universe evolved but not necessarily why it came into existence. Scientists continue to study what may have “preceded” the Big Bang or what conditions allowed the universe to emerge.

    3. Religious and Theological Views

    Many religious traditions hold that a divine being or creator brought the universe into existence. In these views, the universe’s existence reflects the will or purpose of such a being.

    4. Human Limitations

    It’s possible that the question itself is beyond human comprehension. Our cognitive tools and experiences may not be equipped to understand concepts like “nothingness” or ultimate causality.

    The correct answer is It defines and limits the powers of government.

    Explanation: The primary purpose of a constitution is to establish the fundamental framework for governance in a country. It defines the structure of the government, delineates the powers and functions of different institutions, and places limits on governmental power to protect individual rights and maintain the rule of law. While it may also outline the objectives for making laws, create political offices, and aim to secure social justice, its chief purpose is to define and limit the powers of government to prevent abuse and ensure the protection of citizens’ rights.
