  3. Pantograph
  4. Seismograph
Answer and Explanation :-

Answer: Option 4


Seismograph is an instrument that makes a record of seismic waves caused by an earthquake, explosion, or other Earth-shaking phenomenon. Seismographs are equipped with electromagnetic sensors that translate ground motions into electrical changes, which are processed and recorded by the instruments' analog or digital circuits. A record produced by a seismograph on a display screen or paper printout is called a seismogram. Although originally designed to locate natural earthquakes, seismographs have many other uses, such as petroleum exploration, investigation of the Earth's crust and lower layers, and monitoring of volcanic activity.

Of all the hardships and deprivations a people can suffer, I am not sure if the deprivations of art and culture are not the most devastating. As meat and rice are food for the body, art and culture are food for the soul. Starve the body and the person dies starve the soul and the spirit dies.
