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. Why was it necessary to invent instruments to observe an earthquake?
  • a)
    Because an earthquake comes in the night
  • b)
    To make people alert about earthquakes during their conscious as well as unconscious hours
  • c)
    To prove that we are technically advanced
  • d)
    To experiment with the control of man over nature
Correct answer is option 'B'. Can you explain this answer?

Directions: Read the given passage and answer the question that follow...
b) To make people alert about earthquakes during their conscious as well as unconscious hours:

An earthquake comes suddenly, without any warning, like a thief in the night. This unpredictability makes it necessary to invent instruments that can observe earthquakes even when people are sleeping or otherwise unaware of the event.

Importance of inventing instruments:
- Earthquakes can occur at any time, including when people are sleeping or inattentive.
- By inventing instruments to observe earthquakes, scientists can gather data and information about the strength and direction of seismic activity even when people are not consciously aware of it.
- These instruments can help in studying earthquakes, predicting future events, and developing strategies for disaster management.

Need for continuous monitoring:
- Earthquakes can have devastating effects on human lives and infrastructure.
- Continuous monitoring through instruments allows for early detection of seismic activity, which can help in issuing timely warnings and taking necessary precautions to minimize the impact of earthquakes.

Advancement in technology:
- The invention of sophisticated instruments like seismometers has enabled scientists to record and analyze earthquake waves accurately.
- These technological advancements have significantly contributed to our understanding of earthquakes and our ability to mitigate their destructive consequences.
