Problem: Hume maintained that all knowledge, even the most basic beliefs about the natural world, cannot be conclusively established by reason. Rather, he maintained, our beliefs are more a result of accumulated habits, developed in response to accumulated sense experiences. Among his many arguments Hume also added another important slant to the debate about scientific method that of the problem of induction. Hume argued that it requires inductive reasoning to arrive at the premises for the principle of inductive reasoning, and therefore the justification for inductive reasoning is a circular argument. Among Hume's conclusions regarding the problem of induction is that there is no certainty that the future will resemble the past. Thus, as a simple instance posed by Hume, we cannot know with certainty by inductive reasoning that the sun will continue to rise in the East, but instead come to expect it to do so because it has repeatedly done so in the past.
Why did Hume say we expect the sun to rise?
The answer is the following: because it has repeatedly done so in the past

Problem: On July 23, 1990, Leonid Kravchuk was elected to replace Ivashko as parliament chairman. On July 30, Parliament adopted a resolution on military service ordering Ukrainian soldiers "in regions of national conflict such as Armenia and Azerbaijan" to return to Ukrainian territory. On August 1, Parliament voted overwhelmingly to shut down the Chernobyl Nuclear Power Plant. On August 3, it adopted a law on the economic sovereignty of the Ukrainian republic. On August 19, the first Ukrainian Catholic liturgy in 44 years was celebrated at St. George Cathedral. On September 57, the International Symposium on the Great Famine of 19321933 was held in Kiev. On September 8, The first "Youth for Christ" rally since 1933 took place held in Lviv, with 40,000 participants. In September 2830, the Green Party of Ukraine held its founding congress. On September 30, nearly 100,000 people marched in Kiev to protest against the new union treaty proposed by Gorbachev.
Who would succeed Ivashko as the chairman of Parliament?
The answer is the following: Leonid Kravchuk

Problem: Nanjing is the intersection of Yangtze River, an east-west water transport artery, and NanjingBeijing railway, a south-north land transport artery, hence the name "door of the east and west, throat of the south and north". Furthermore, the west part of the Ningzhen range is in Nanjing; the Loong-like Zhong Mountain is curling in the east of the city; the tiger-like Stone Mountain is crouching in the west of the city, hence the name "the Zhong Mountain, a dragon curling, and the Stone Mountain, a tiger crouching". Mr. Sun Yet-sen spoke highly of Nanjing in the "Constructive Scheme for Our Country", "The position of Nanjing is wonderful since mountains, lakes and plains all integrated in it. It is hard to find another city like this."
What mountain lies in the west of Nanjing?
The answer is the following: Stone Mountain

Problem: Despite these detailed standard definitions, cameras typically do not clearly indicate whether the user "ISO" setting refers to the noise-based speed, saturation-based speed, or the specified output sensitivity, or even some made-up number for marketing purposes. Because the 1998 version of ISO 12232 did not permit measurement of camera output that had lossy compression, it was not possible to correctly apply any of those measurements to cameras that did not produce sRGB files in an uncompressed format such as TIFF. Following the publication of CIPA DC-004 in 2006, Japanese manufacturers of digital still cameras are required to specify whether a sensitivity rating is REI or SOS.[citation needed]
What did the 1998 version of ISO 12232 not permit?
The answer is the following:
measurement of camera output that had lossy compression
