[EX Q]: Passage: Turner Classic Movies essentially operates as a commercial-free service, with the only advertisements on the network being shown between features – which advertise TCM products, network promotions for upcoming special programs and the original trailers for films that are scheduled to be broadcast on TCM (particularly those that will air during the primetime hours), and featurettes about classic film actors and actresses. In addition to this, extended breaks between features are filled with theatrically released movie trailers and classic short subjects – from series such as The Passing Parade, Crime Does Not Pay, Pete Smith Specialties, and Robert Benchley – under the banner name TCM Extras (formerly One Reel Wonders). In 2007, some of the short films featured on TCM were made available for streaming on TCM's website. Partly to allow these interstitials, Turner Classic Movies schedules its feature films either at the top of the hour or at :15, :30 or :45 minutes past the hour, instead of in timeslots of varying five-minute increments.
[EX A]: What were TCM products previously known as?

[EX Q]: Passage: Since about the year 2000, a growing number of Internet pharmacies have been established worldwide. Many of these pharmacies are similar to community pharmacies, and in fact, many of them are actually operated by brick-and-mortar community pharmacies that serve consumers online and those that walk in their door. The primary difference is the method by which the medications are requested and received. Some customers consider this to be more convenient and private method rather than traveling to a community drugstore where another customer might overhear about the drugs that they take. Internet pharmacies (also known as online pharmacies) are also recommended to some patients by their physicians if they are homebound.
[EX A]: When did internet pharmacies begin to end?

[EX Q]: Passage: In 1607, English Chief Justice Sir Edward Coke said in the Case of Prohibitions (according to his own report) "that the law was the golden met-wand and measure to try the causes of the subjects; and which protected His Majesty in safety and peace: with which the King was greatly offended, and said, that then he should be under the law, which was treason to affirm, as he said; to which I said, that Bracton saith, quod Rex non debed esse sub homine, sed sub Deo et lege (That the King ought not to be under any man but under God and the law.)."
