Input: Read this: The use of uranium in its natural oxide form dates back to at least the year 79 CE, when it was used to add a yellow color to ceramic glazes. Yellow glass with 1% uranium oxide was found in a Roman villa on Cape Posillipo in the Bay of Naples, Italy, by R. T. Gunther of the University of Oxford in 1912. Starting in the late Middle Ages, pitchblende was extracted from the Habsburg silver mines in Joachimsthal, Bohemia (now Jáchymov in the Czech Republic), and was used as a coloring agent in the local glassmaking industry. In the early 19th century, the world's only known sources of uranium ore were these mines.
Question: What color of ceramic glaze was subtracted from uranium oxide?

Output: unanswerable

Input: Read this: In 1950 Egypt closed the Suez Canal to Israeli shipping and tensions mounted as armed clashes took place along Israel's borders. During the 1950s, Israel was frequently attacked by Palestinian fedayeen, nearly always against civilians, mainly from the Egyptian-occupied Gaza Strip, leading to several Israeli counter-raids. In 1956, Great Britain and France aimed at regaining control of the Suez Canal, which the Egyptians had nationalized (see the Suez Crisis). The continued blockade of the Suez Canal and Straits of Tiran to Israeli shipping, together with the growing amount of Fedayeen attacks against Israel's southern population, and recent Arab grave and threatening statements, prompted Israel to attack Egypt. Israel joined a secret alliance with Great Britain and France and overran the Sinai Peninsula but was pressured to withdraw by the United Nations in return for guarantees of Israeli shipping rights in the Red Sea via the Straits of Tiran and the Canal[citation needed]. The war resulted in significant reduction of Israeli border infiltration.
Question: What did the war result in?

Output:
significant reduction of Israeli border infiltration
