Problem: Mali:

Although Mali has enjoyed a reasonably good inter-ethnic relationships based on the long history of coexistence, some hereditary servitude and bondage relationship exist, as well as ethnic tension between settled Songhai and nomadic Tuaregs of the north. Due to a backlash against the northern population after independence, Mali is now in a situation where both groups complain about discrimination on the part of the other group. This conflict also plays a role in the continuing Northern Mali conflict where there is a tension between both Tuaregs and the Malian government, and the Tuaregs and radical Islamists who are trying to establish sharia law.

Problem: The permanent snow cover necessary for glacier formation is affected by factors such as the degree of slope on the land, amount of snowfall and the winds. Glaciers can be found in all latitudes except from 20 to 27 north and south of the equator where the presence of the descending limb of the Hadley circulation lowers precipitation so much that with high insolation snow lines reach above 6,500 m (21,330 ft). Between 19N and 19S, however, precipitation is higher and the mountains above 5,000 m (16,400 ft) usually have permanent snow.
Between which north latitudes are glaciers not found?

Answer: 20 to 27 north

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The first lighting used on an airport was during the latter part of the 1920s; in the 1930s approach lighting came into use. These indicated the proper direction and angle of descent. The colours and flash intervals of these lights became standardized under the International Civil Aviation Organization (ICAO). In the 1940s, the slope-line approach system was introduced. This consisted of two rows of lights that formed a funnel indicating an aircraft's position on the glideslope. Additional lights indicated incorrect altitude and direction.
When was the slope-line approach system introduced?
A: 1940s

Context and question: In some countries anti-Masonry is often related to antisemitism and anti-Zionism. For example, In 1980, the Iraqi legal and penal code was changed by Saddam Hussein's ruling Ba'ath Party, making it a felony to "promote or acclaim Zionist principles, including Freemasonry, or who associate [themselves] with Zionist organisations". Professor Andrew Prescott of the University of Sheffield writes: "Since at least the time of the Protocols of the Elders of Zion, antisemitism has gone hand in hand with anti-masonry, so it is not surprising that allegations that 11 September was a Zionist plot have been accompanied by suggestions that the attacks were inspired by a masonic world order".
What are two things that anti-masonry is always associated with?
Answer: unanswerable
