Since you have provided no options, the best I can do is to describe lithography and hope that it helps:
In the first step, an image is drawn on a stone, typically with wax or oil. Then ink is spread on the whole stone, but it will not stay on the parts with oil or wax, only on the other parts. Then paper is pressed against the stone, and an image appears, because the ink adheres to the paper- you can then make multiple copies of the image.
The orchestral brass instruments are the trumpet, French horn, trombone, and tuba. As with the woodwinds, the number of each of these instruments varies depending on the size of the orchestra and the piece being played. There are usually two to five each of trumpets, horns, and trombones, and one or two tubas.:)
