I belive this is repair and maintenance.
hope this helps!
The correct answer is option (a) Scanning tunneling microscope.
Microscopes are used to see the objects at molecular level. Scanning tunneling microscope( STM) is a type of optical microscope that uses optics(light) and lenses to see the enlarged size of the object. This microscope use a small metal tip under a high voltage. when this tip of microscope is brought close to the metal, the metallic tip of microscope draws electrons from the atom (metal) to be observed. This generates an electric current. There is a computer system attached to the microscope that detects the change in the electric current. Computer plots the change in position of atoms in metal.
The correct answer is this: ZEITOUN SPOT FISH SWIMMING IN THE FLOOD WATER.
The passage given above was drawn from an account of Hurricane Katrina by Dave Eggers. In the passage, he described the hurricane experience as an apolycapses, thus likening the event to the great destruction that will befall the earth at the end of the world as recorded in the bible in the book of Revelation. The hurricane was so bad that those animals that can not fly were carried away in the flood, even the fish inside the water were affected.
