Article: Downstream operations, which now also includes the chemicals business, generates a third of Shell's profits worldwide and is known for its global network of more than 40,000 petrol stations and its 47 oil refineries. The downstream business, which in some countries also included oil refining, generally included a retail petrol station network, lubricants manufacture and marketing, industrial fuel and lubricants sales and a host of other product/market sectors such as LPG and bitumen. The practice in Shell was that these businesses were essentially local and that they were best managed by local "operating companies" – often with middle and senior management reinforced by expatriates. In the 1990s, this paradigm began to change, and the independence of operating companies around the world was gradually reduced. Today, virtually all of Shell's operations in various businesses are much more directly managed from London and The Hague. The autonomy of "operating companies" has been largely removed, as more "global businesses" have been created.

Question: Prior to the 1990s, Shell's downstream businesses were essentially considered what kind of businesses?
Ans: local


Article: At high altitudes, Neptune's atmosphere is 80% hydrogen and 19% helium. A trace amount of methane is also present. Prominent absorption bands of methane exist at wavelengths above 600 nm, in the red and infrared portion of the spectrum. As with Uranus, this absorption of red light by the atmospheric methane is part of what gives Neptune its blue hue, although Neptune's vivid azure differs from Uranus's milder cyan. Because Neptune's atmospheric methane content is similar to that of Uranus, some unknown atmospheric constituent is thought to contribute to Neptune's colour.

Question: What planet also gets it's color from atmospheric constituent? 
Ans: Uranus


Article: In many places in Switzerland, household rubbish disposal is charged for. Rubbish (except dangerous items, batteries etc.) is only collected if it is in bags which either have a payment sticker attached, or in official bags with the surcharge paid at the time of purchase. This gives a financial incentive to recycle as much as possible, since recycling is free. Illegal disposal of garbage is not tolerated but usually the enforcement of such laws is limited to violations that involve the unlawful disposal of larger volumes at traffic intersections and public areas. Fines for not paying the disposal fee range from CHF 200–500.

Question: What does Switzerland charge for the disposal of in order to encourage recycling?
Ans: Rubbish


Article: In the United States, there was a movement to resettle American free blacks and freed slaves in Africa. The American Colonization Society was founded in 1816 in Washington, DC for this purpose, by a group of prominent politicians and slaveholders. But its membership grew to include mostly people who supported abolition of slavery. Slaveholders wanted to get free people of color out of the South, where they were thought to threaten the stability of the slave societies. Some abolitionists collaborated on relocation of free blacks, as they were discouraged by discrimination against them in the North and believed they would never be accepted in the larger society. Most African Americans, who were native-born by this time, wanted to improve conditions in the United States rather than emigrate. Leading activists in the North strongly opposed the ACS, but some free blacks were ready to try a different environment.

Question: What is "the american colonization society"?
Ans:
a movement to resettle American free blacks and freed slaves in Africa.
