Directions (Q. 1 to 5) : Read the following passage and answer the questions given below it in the context of the passage.
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 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, penholder 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-1 This passage says that early instruments for measuring earthquakes were
faulty in design

To experiment with the control of man over nature
A simple device which consisted of rods that stood up on end like ninepins was replaced by a more sophisticated one because it failed
to record the facts with a pen on paper
to measure a severe earthquake
to record the direction of the earthquake
to measure a gentle earthquake
The everyday observation referred to in the passage relates to
the tendency of a standing person to fall when a bus or train moves suddenly
a moving bus or train

neither pen nor paper that should move
the pen that should move just as it moves when we write on paper
