You may have never heard of Ladislao Biro, but you have certainly heard of the pen he invented—the ballpoint pen, or biro. Before Biro invented his pen, people wrote with fountain pens. The ink smudged(弄脏) and blotted and the pens sometimes leaked. In the 1930s Biro was a magazine editor in Budapest in Hungary. He noticed that the inks which the magazine’s printers used dried very quickly. Biro wondered if quick-drying inks could be used in pens. He came up with the idea of a tube of ink with a free-moving ball on the end. As a person wrote, the ball collected ink from the tube and rolled it on to the paper. The pen would be cheap and could be thrown away when the ink ran out.
Biro began to work on his invention, but before he could patent it the Second World War broke out. Biro left war-torn Europe and fled to Buenos Aires in Argentina. There, he and his brother Georg, who was a chemist, began to improve the pen. In the early 1940s Biro began to manufacture his new pen, the biro. In 1944, he sold his invention to another company, who began to mass-produce the pen for the British and American armed forces.
Biro was pleased that his pen was popular, but he did not gain much from his invention. The biro was later sold to the French firm, Bic, who now sell twelve million pens a day. Biro sank into obscurity in South America. His name, however, has become a household word.
48. The reasons for the popularity of ballpoint pens are these EXCEPT that_______.
A. the inks dried very quickly B. they were cheap
