Select the correct answer using the code given below : Correct Answer 1 and 2 only

The correct answer is 1 and 2 only.

  • Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the original. The object experiencing fission is usually a cell,
  • Fission, in physics, is defined as the splitting of a nucleus into two daughter nuclei.
  • The amount of energy produced is huge.
  • Uranium is the primary fuel that is used in power plants.
  • When the nucleus of an atom splits into lighter nuclei through a nuclear reaction the process is termed nuclear fission.
  • The discovery of nuclear fission began with the discovery of the neutron in 1932 by James Chadwick in England.
  • Nuclear fission of heavy elements was discovered in 1938 by German Otto Hahn and Fritz Strassmann.
  • It was explained theoretically in 1939 by Lise Meitner and Otto Robert Frisch.
  • In the fission process, radioactive products are formed, and several neutrons are emitted.
  • These neutrons can induce fission in a nearby nucleus of fissionable material and release more neutrons causing a chain reaction.

A passage is given with five questions following it. Read the passage carefully and select the best answer to each question out of the given fouralternatives. Just as space permeates everything in the universe, love permeates every part, every aspect of creation. If there is one answer to the question, “How and why doesthis world exist?” the answer, in one word, is Love. Rather, the answer is Pure Love, since the word love has lost its meaning. Your very existence is an expression of pure unconditional love of the Source (you may call it Consciousness, Creator, God, Divine Self). This is the truth of your being.True love transcends both love and hatred. It is unconditional, unquestioning, boundless, unchanging love. It is overflowing love of the Source for the Source throughall of creation. True love is way beyond the personalized love that two or more individuals assert on one another. Personalized love, though apparently selfless, is rooted in desiresand conditional satisfaction. We have been brought up in a society that judges love based on conditions. We have been made to believe that we can receive love only when we fit into peoplesexpectations. If we are not good enough, we will be deprived of love. These beliefs have influenced the collective psyche of families, groups, communities, and societies since generations to such an extent that love has been reduced tofear of denial. We need to shift from the paradigm of false conditional love to the essence of pure unconditional love . The experience of true love comes with surrender of the false I, in letting go of the feeling of separateness. Without this sacrifice, it is not possible to attain divinelove. When this separate I is discarded, you embrace everything in oneness and catch a glimpse of pure love. True love can be experienced only through giving, not by demanding. People who exist in your life are not here to love you. They are here to remind you that you arethe Source of Love. By knowing that you are the Source of love, you can love yourself, instead of waiting to receive love from the world. Ask yourself, “Why do I need an agent to love myself?” Waiting for the world to love you, is like hiring an agent to love yourself! It is time for you to honor yourself as the Source of love. You have undertaken this human journey to realize and express the boundless love that you truly are. According to the passage, which of the following statement is not TRUE?
