When people first wrote with pens , they had to put the penpoint into ink after every few letters. Later someone invented a fountain pen and this kind of pen could hold ink inside. A fountain pen can write several pages before you have to fill it again. Two brothers, Ladislao and Georg Biro, invented the ballpoint pen that we use today. They left their country Hungary and started producing ballpoint pens in England in 1943 during World War II. Later, a French company called Bic bought the Biro's company. Someone calls ballpoint pens bics. Australians call them biros. Whatever we call them, we use them every day. Options: A Some famous inventors. B The invention of some kinds of pens.
