Fill in the blank with the right option. All great thinkers live and…

Answer: move on

• Why this is correct: "live and move on a high plane of thought" is an established expression meaning to both exist and act at an elevated level of thinking. The preposition "on" indicates being at or on a particular level or plane.

• Why the other choices are wrong:

  • "move at" — unidiomatic here; "at" does not convey the sense of existing and acting on a plane.

  • "move with" — suggests accompaniment and does not fit the intended meaning.

  • "move by" — implies method or passing by, which does not express living and acting at a particular level.

• Conclusion: "move on" completes the sentence correctly: "All great thinkers live and move on a high plane of thought."
