The problem: Answer a question about this article:
Often taxonomists prefer to use phylogenetic analysis to determine whether a population can be considered a subspecies. Phylogenetic analysis relies on the concept of derived characteristics that are not shared between groups, usually applying to populations that are allopatric (geographically separated) and therefore discretely bounded. This would make a subspecies, evolutionarily speaking, a clade – a group with a common evolutionary ancestor population. The smooth gradation of human genetic variation in general tends to rule out any idea that human population groups can be considered monophyletic (cleanly divided), as there appears to always have been considerable gene flow between human populations. Rachel Caspari (2003) have argued that clades are by definition monophyletic groups (a taxon that includes all descendants of a given ancestor) and since no groups currently regarded as races are monophyletic, none of those groups can be clades.
What is a tongue twister of a word that merely means "cleanly divided"?
****
The answer: monophyletic

Von Neumann worked on lattice theory between 1937 and 1939. Von Neumann provided an abstract exploration of dimension in completed complemented modular topological lattices: "Dimension is determined, up to a positive linear transformation, by the following two properties. It is conserved by perspective mappings ("perspectivities") and ordered by inclusion. The deepest part of the proof concerns the equivalence of perspectivity with "projectivity by decomposition"—of which a corollary is the transitivity of perspectivity." Garrett Birkhoff writes: "John von Neumann's brilliant mind blazed over lattice theory like a meteor".
What properties determine dimension in lattice theory?
****
The answer: conserved by perspective mappings ("perspectivities") and ordered by inclusion

The problem: Answer a question about this article:
The palace, like Windsor Castle, is owned by the Crown Estate. It is not the monarch's personal property, unlike Sandringham House and Balmoral Castle. Many of the contents from Buckingham Palace, Windsor Castle, Kensington Palace, and St James's Palace are part of the Royal Collection, held in trust by the Sovereign; they can, on occasion, be viewed by the public at the Queen's Gallery, near the Royal Mews. Unlike the palace and the castle, the purpose-built gallery is open continually and displays a changing selection of items from the collection. It occupies the site of the chapel destroyed by an air raid in World War II. The palace's state rooms have been open to the public during August and September and on selected dates throughout the year since 1993. The money raised in entry fees was originally put towards the rebuilding of Windsor Castle after the 1992 fire devastated many of its state rooms. 476,000 people visited the palace in the 2014–15 financial year.
Where can the public view the Royal Collection?
****
The answer:
at the Queen's Gallery
