  1. Ridhima Mehta

    Logic – For the first blank, astonishing, vital and essential fit but for the second blank only familiar fits because it mentions ‘existing knowledge’ of a phenomenon.

    1. TG.Prabhat

      Hi Ridhima, it is possible for knowledge about isolated phenomana to exist, thus making option 4. a possible answer. But, option 1 does fit best 🙂

  2. TG.Prabhat

    The most accurate option is 1. Option 4 is possible but less plausible. Whether the most essential discoveries in science are about isolated phenomena or not can be highly debatable.

    Astonishing: extremely surprising or impressive; amazing.
    Asinine: extremely stupid or foolish.
    Moribund: (of a person) at the point of death; (of a thing) in terminal decline.
    Alien: unfamiliar and disturbing or distasteful.
    Isolated: remote, single, exceptional

    Everyone- great going! Keep it up 🙂
