Direction: Read the following passage and answer the given question.
An earthquake comes like a thief in the night, without warning. It was necessary therefore to invent instruments that neither slumbered nor slept. Some devices were quite simple. One, for instance, consisted of rods of various lengths and thicknesses which would stand up on end like ninepins. When a shock came, it shook the rigid table upon which these stood. If it were gentle, only the more unstable rods fell. If it were severe, they all fell. Thus, the rods by falling and by the direction in which they fell, recorded for the slumbering scientist, the strength of a shock that was too weak to waken him and know the direction from which it came.
But instruments far more delicate than that were needed if any really serious advance was to be made. The ideal to be aimed at was to devise an instrument that could record with a pen on paper the movements of the ground or of the table as the quake passed by. While I write, my pen moves but the paper keeps still. With practice, no doubt, I could, in time, learn to write by holding the pen still while the paper moved. That sounds a silly suggestion, but that was precisely the idea adopted in some of the early instruments (seismometers) for recording earthquake waves. But when the table, pen holder, and paper are all moving, how is it possible to write legibly? The key to a solution to that problem lay in everyday observation. Why does a person standing on a bus or train tend to fall when a sudden start is made? It is because his feet move on, but his head stays still.
Q. The early seismometers adopted the idea that in order to record the earthquake, it is
  • a)
    The pen that should move just as it moves when we write on paper
  • b)
    The pen that should stay still and the paper should move
  • c)
    Both the pen and the paper that should move
  • d)
    Neither the pen nor the paper that should move
Correct answer is option 'B'. Can you explain this answer?

Explanation:

Early Seismometers:
- The early seismometers adopted the idea that the pen should stay still and the paper should move in order to record the earthquake.
- The concept was inspired by everyday observation, where a person tends to fall when a sudden start is made on a bus or train.
- This happens because the person's feet move along with the vehicle, but the head stays still.
- Applying this principle to the seismometers, it was understood that keeping the pen still while allowing the paper to move would result in legible recordings of the earthquake waves.
- This method allowed scientists to accurately track the movements of the ground or table as the quake passed by.

Challenges:
- The challenge was to find a way to write legibly when both the table and the pen holder were moving during an earthquake.
- By keeping the pen stationary while allowing the paper to move, the seismometers were able to overcome this challenge effectively.

Conclusion:
- The early seismometers successfully recorded earthquake waves by adopting the idea that the pen should stay still while the paper moves.
- This method provided a significant advancement in the field of seismology and allowed scientists to study earthquakes more accurately.
