Input: Read this: On 29 October 1956, Israeli forces crossed the Sinai Peninsula, overwhelmed Egyptian army posts, and quickly advanced to their objectives. Two days later, British and French planes bombarded Egyptian airfields in the canal zone. Nasser ordered the military's high command to withdraw the Egyptian Army from Sinai to bolster the canal's defenses. Moreover, he feared that if the armored corps was dispatched to confront the Israeli invading force and the British and French subsequently landed in the canal city of Port Said, Egyptian armor in the Sinai would be cut off from the canal and destroyed by the combined tripartite forces. Amer strongly disagreed, insisting that Egyptian tanks meet the Israelis in battle. The two had a heated exchange on 3 November, and Amer conceded. Nasser also ordered blockage of the canal by sinking or otherwise disabling forty-nine ships at its entrance.
Question: What did the British and French air forces bomb?

Output: Egyptian airfields in the canal zone

QUES: Others argue that reason was generally held in high regard during the Middle Ages. Science historian Edward Grant writes, "If revolutionary rational thoughts were expressed [in the 18th century], they were only made possible because of the long medieval tradition that established the use of reason as one of the most important of human activities". Also, contrary to common belief, David Lindberg writes, "the late medieval scholar rarely experienced the coercive power of the church and would have regarded himself as free (particularly in the natural sciences) to follow reason and observation wherever they led".

Who argued that scholars in the Middle Ages were rarely coerced by the Church?
What is the answer?
ANS: David Lindberg

Gladstone returned to power after the 1892 general election; he was 82 years old. Victoria objected when Gladstone proposed appointing the Radical MP Henry Labouchere to the Cabinet, so Gladstone agreed not to appoint him. In 1894, Gladstone retired and, without consulting the outgoing prime minister, Victoria appointed Lord Rosebery as prime minister. His government was weak, and the following year Lord Salisbury replaced him. Salisbury remained prime minister for the remainder of Victoria's reign.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was returned to power in 1892?
Ah, so.. Gladstone

Question: Sony confirmed that there was an error and stated that they were narrowing down the issue and were continuing to work to restore service. By March 2 (UTC), 2010, owners of original PS3 models could connect to PSN successfully and the clock no longer showed December 31, 1999. Sony stated that the affected models incorrectly identified 2010 as a leap year, because of a bug in the BCD method of storing the date. However, for some users, the hardware's operating system clock (mainly updated from the internet and not associated with the internal clock) needed to be updated manually or by re-syncing it via the internet.
Try to answer this question if possible: What storage system for dates led to the system disk error?
Answer: unanswerable

Context and question: In addition to a spoken standard and a closely related written standard, Czech has several regional dialects primarily used in rural areas by speakers less proficient in other dialects or standard Czech. During the second half of the twentieth century, Czech dialect use began to weaken. By the early 1990s dialect use was stigmatized, associated with the shrinking lower class and used in literature or other media for comedic effect. Increased travel and media availability to dialect-speaking populations has encouraged them to shift to (or add to their own dialect) standard Czech. Although Czech has received considerable scholarly interest for a Slavic language, this interest has focused primarily on modern standard Czech and ancient texts rather than dialects. Standard Czech is still the norm for politicians, businesspeople and other Czechs in formal situations, but Common Czech is gaining ground in journalism and the mass media.
What has increased among politicians and business people since 1990 so they are more well known locally?
Answer:
unanswerable
