Directions: Read the given passage and answer the question that follows.
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 table, pen holder and paper are all moving, how is it possible to write legibly? The key to a solution of that problem lay in an everyday observation. Why does a person standing in 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 'everyday observation' referred to in the passage relates to _____.
  • a)
    the greater movement of a bus or a train, especially when an earthquake occurs
  • b)
    the sudden start of a bus or a train full of passengers
  • c)
    the tendency of a standing person to fall when a bus or train moves suddenly
  • d)
    people standing even in a moving bus or a train
Correct answer is option 'C'. Can you explain this answer?

Explanation:

The everyday observation referred to in the passage relates to ____.

The passage mentions an everyday observation where a person tends to fall when a sudden start is made in a bus or train. This observation is crucial in understanding the concept of stability and motion during earthquakes.

Explanation of the observation:

- When a bus or train makes a sudden start, the passengers inside tend to lose balance and may fall.
- This happens because the lower part of the body, i.e., the feet, moves with the bus or train, while the upper part, i.e., the head, tends to stay still due to inertia.
- This difference in motion between the lower and upper parts of the body results in a loss of balance and the tendency to fall.

Relation to earthquake detection:

- This observation was crucial in the development of seismometers to detect and record earthquake waves.
- Just like the standing person in a moving bus or train, the seismometer needed to have a stable upper part (pen holder and paper) while the lower part (table) moved during an earthquake.
- By applying the concept of inertia and stability, scientists were able to design instruments that could accurately record the movement of the ground during an earthquake.

In conclusion, the everyday observation of people losing balance in a moving bus or train provided a key insight into designing effective seismometers for detecting and recording earthquake waves.
