Problem: In 1838, Claridge obtained patents in Scotland on 27 March, and Ireland on 23 April, and in 1851 extensions were sought for all three patents, by the trustees of a company previously formed by Claridge. This was Claridge's Patent Asphalte Company, formed in 1838 for the purpose of introducing to Britain "Asphalte in its natural state from the mine at Pyrimont Seysell in France", and "laid one of the first asphalt pavements in Whitehall". Trials were made of the pavement in 1838 on the footway in Whitehall, the stable at Knightsbridge Barracks, "and subsequently on the space at the bottom of the steps leading from Waterloo Place to St. James Park". "The formation in 1838 of Claridge's Patent Asphalte Company (with a distinguished list of aristocratic patrons, and Marc and Isambard Brunel as, respectively, a trustee and consulting engineer), gave an enormous impetus to the development of a British asphalt industry". "By the end of 1838, at least two other companies, Robinson's and the Bastenne company, were in production", with asphalt being laid as paving at Brighton, Herne Bay, Canterbury, Kensington, the Strand, and a large floor area in Bunhill-row, while meantime Claridge's Whitehall paving "continue(d) in good order".
By 1838 how many companies beside Claridge's were offering asphalt?
The answer is the following: two

Problem: In Chapter II, Darwin specifies that the distinction between species and varieties is arbitrary, with experts disagreeing and changing their decisions when new forms were found. He concludes that "a well-marked variety may be justly called an incipient species" and that "species are only strongly marked and permanent varieties". He argues for the ubiquity of variation in nature. Historians have noted that naturalists had long been aware that the individuals of a species differed from one another, but had generally considered such variations to be limited and unimportant deviations from the archetype of each species, that archetype being a fixed ideal in the mind of God. Darwin and Wallace made variation among individuals of the same species central to understanding the natural world.
What did Darwin say that a "well marked variety" could be called?
The answer is the following: incipient species"

Problem: TCM regularly airs a "Star of the Month" throughout the year on Wednesdays starting at 8:00 p.m. Eastern Time, in which most, if not all, feature films from a classic film star are shown during that night's schedule. Hosted by Robert Osbourne, the network also marks the occurrence of a film actor's birthday (either antemortem or posthumously) or recent death with day- or evening-long festivals showcasting several of that artist's best, earliest or least-known pictures; by effect, marathons scheduled in honor of an actor's passing (which are scheduled within a month after their death) pre-empt films originally scheduled to air on that date. TCM also features a monthly program block called the "TCM Guest Programmer", in which Osborne is joined by celebrity guests responsible for choosing that evening's films (examples of such programmers during 2012 include Jules Feiffer, Anthony Bourdain, Debra Winger, Ellen Barkin, Spike Lee, Regis Philbin and Jim Lehrer); an offshoot of this block featuring Turner Classic Movies employees aired during February 2011.
In what year did Spike Lee appear as a TCM Guest Programmer?
The answer is the following: 2012

Problem: While short-term memory encodes information acoustically, long-term memory encodes it semantically: Baddeley (1966) discovered that, after 20 minutes, test subjects had the most difficulty recalling a collection of words that had similar meanings (e.g. big, large, great, huge) long-term. Another part of long-term memory is episodic memory, "which attempts to capture information such as 'what', 'when' and 'where'". With episodic memory, individuals are able to recall specific events such as birthday parties and weddings.
How does long term memory encode information?
The answer is the following:
semantically
