Here is a question about this article: A person from Ann Arbor is called an "Ann Arborite", and many long-time residents call themselves "townies". The city itself is often called "A" ("A-squared") or "A2" ("A two") or "AA", "The Deuce" (mainly by Chicagoans), and "Tree Town". With tongue-in-cheek reference to the city's liberal political leanings, some occasionally refer to Ann Arbor as "The People's Republic of Ann Arbor" or "25 square miles surrounded by reality", the latter phrase being adapted from Wisconsin Governor Lee Dreyfus's description of Madison, Wisconsin. In A Prairie Home Companion broadcast from Ann Arbor, Garrison Keillor described Ann Arbor as "a city where people discuss socialism, but only in the fanciest restaurants." Ann Arbor sometimes appears on citation indexes as an author, instead of a location, often with the academic degree MI, a misunderstanding of the abbreviation for Michigan. Ann Arbor has become increasingly gentrified in recent years.
What is the answer to this question: In recent years what has Ann Arbor become?
****
So... gentrified

Here is a question about this article: From 1898, it was commonly accepted that the name was of Celtic origin and meant place belonging to a man called *Londinos; this explanation has since been rejected. Richard Coates put forward an explanation in 1998 that it is derived from the pre-Celtic Old European *(p)lowonida, meaning 'river too wide to ford', and suggested that this was a name given to the part of the River Thames which flows through London; from this, the settlement gained the Celtic form of its name, *Lowonidonjon; this requires quite a serious amendment however. The ultimate difficulty lies in reconciling the Latin form Londinium with the modern Welsh Llundain, which should demand a form *(h)londinion (as opposed to *londinion), from earlier *loundiniom. The possibility cannot be ruled out that the Welsh name was borrowed back in from English at a later date, and thus cannot be used as a basis from which to reconstruct the original name.
What is the answer to this question: What is the meaning of the later-believed pre-Celtic Old European origin of London's name?

So... 'river too wide to ford

Here is a question about this article: One of the first quantum effects to be explicitly noticed (but not understood at the time) was a Maxwell observation involving hydrogen, half a century before full quantum mechanical theory arrived. Maxwell observed that the specific heat capacity of H2 unaccountably departs from that of a diatomic gas below room temperature and begins to increasingly resemble that of a monatomic gas at cryogenic temperatures. According to quantum theory, this behavior arises from the spacing of the (quantized) rotational energy levels, which are particularly wide-spaced in H2 because of its low mass. These widely spaced levels inhibit equal partition of heat energy into rotational motion in hydrogen at low temperatures. Diatomic gases composed of heavier atoms do not have such widely spaced levels and do not exhibit the same effect.
What is the answer to this question: What cause H2 to resemble monatomic gas?
****
So...
spacing of the (quantized) rotational energy levels
