Problem: Namibia:

The dry lands of Namibia were inhabited since early times by San, Damara, and Namaqua, and since about the 14th century AD by immigrating Bantu who came with the Bantu expansion. Most of the territory became a German Imperial protectorate in 1884 and remained a German colony until the end of World War I. In 1920, the League of Nations mandated the country to South Africa, which imposed its laws and, from 1948, its apartheid policy. The port of Walvis Bay and the offshore Penguin Islands had been annexed by the Cape Colony under the British crown by 1878 and had become an integral part of the new Union of South Africa at its creation in 1910.

In what year was the League of Nations formed?

Problem: There are a number of aids available to pilots, though not all airports are equipped with them. A visual approach slope indicator (VASI) helps pilots fly the approach for landing. Some airports are equipped with a VHF omnidirectional range (VOR) to help pilots find the direction to the airport. VORs are often accompanied by a distance measuring equipment (DME) to determine the distance to the VOR. VORs are also located off airports, where they serve to provide airways for aircraft to navigate upon. In poor weather, pilots will use an instrument landing system (ILS) to find the runway and fly the correct approach, even if they cannot see the ground. The number of instrument approaches based on the use of the Global Positioning System (GPS) is rapidly increasing and may eventually be the primary means for instrument landings.
What also goes along with the VASI?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Although Greg argued that an editor should be free to use his judgment to choose between competing substantive readings, he suggested that an editor should defer to the copy-text when "the claims of two readings ... appear to be exactly balanced. ... In such a case, while there can be no logical reason for giving preference to the copy-text, in practice, if there is no reason for altering its reading, the obvious thing seems to be to let it stand." The "exactly balanced" variants are said to be indifferent.
An editor should not defer to what when variants are balanced?
A: unanswerable

Question: In most taxonomies, the flowering plants are treated as a coherent group. The most popular descriptive name has been Angiospermae (Angiosperms), with Anthophyta ("flowering plants") a second choice. These names are not linked to any rank. The Wettstein system and the Engler system use the name Angiospermae, at the assigned rank of subdivision. The Reveal system treated flowering plants as subdivision Magnoliophytina (Frohne & U. Jensen ex Reveal, Phytologia 79: 70 1996), but later split it to Magnoliopsida, Liliopsida, and Rosopsida. The Takhtajan system and Cronquist system treat this group at the rank of division, leading to the name Magnoliophyta (from the family name Magnoliaceae). The Dahlgren system and Thorne system (1992) treat this group at the rank of class, leading to the name Magnoliopsida. The APG system of 1998, and the later 2003 and 2009 revisions, treat the flowering plants as a clade called angiosperms without a formal botanical name. However, a formal classification was published alongside the 2009 revision in which the flowering plants form the Subclass Magnoliidae.
Is there an answer to this question: What does anthophyta mean?

Answer: flowering plants


Problem: Queen Victoria:

In 1830, the Duchess of Kent and Conroy took Victoria across the centre of England to visit the Malvern Hills, stopping at towns and great country houses along the way. Similar journeys to other parts of England and Wales were taken in 1832, 1833, 1834 and 1835. To the King's annoyance, Victoria was enthusiastically welcomed in each of the stops. William compared the journeys to royal progresses and was concerned that they portrayed Victoria as his rival rather than his heiress presumptive. Victoria disliked the trips; the constant round of public appearances made her tired and ill, and there was little time for her to rest. She objected on the grounds of the King's disapproval, but her mother dismissed his complaints as motivated by jealousy, and forced Victoria to continue the tours. At Ramsgate in October 1835, Victoria contracted a severe fever, which Conroy initially dismissed as a childish pretence. While Victoria was ill, Conroy and the Duchess unsuccessfully badgered her to make Conroy her private secretary. As a teenager, Victoria resisted persistent attempts by her mother and Conroy to appoint him to her staff. Once queen, she banned him from her presence, but he remained in her mother's household.

What town did Victoria visit in the center of England on her trip without the Dutchess of kent and Conroy?
