Problem: Iranian languages:

Following the Islamic Conquest of Persia (Iran), there were important changes in the role of the different dialects within the Persian Empire. The old prestige form of Middle Iranian, also known as Pahlavi, was replaced by a new standard dialect called Dari as the official language of the court. The name Dari comes from the word darbâr (دربار), which refers to the royal court, where many of the poets, protagonists, and patrons of the literature flourished. The Saffarid dynasty in particular was the first in a line of many dynasties to officially adopt the new language in 875 CE. Dari may have been heavily influenced by regional dialects of eastern Iran, whereas the earlier Pahlavi standard was based more on western dialects. This new prestige dialect became the basis of Standard New Persian. Medieval Iranian scholars such as Abdullah Ibn al-Muqaffa (8th century) and Ibn al-Nadim (10th century) associated the term "Dari" with the eastern province of Khorasan, while they used the term "Pahlavi" to describe the dialects of the northwestern areas between Isfahan and Azerbaijan, and "Pârsi" ("Persian" proper) to describe the Dialects of Fars. They also noted that the unofficial language of the royalty itself was yet another dialect, "Khuzi", associated with the western province of Khuzestan.

Problem: Houston:

The Houston–The Woodlands–Sugar Land metropolitan area is served by one public television station and two public radio stations. KUHT (HoustonPBS) is a PBS member station and is the first public television station in the United States. Houston Public Radio is listener-funded and comprises two NPR member stations: KUHF (KUHF News) and KUHA (Classical 91.7). KUHF is news/talk radio and KUHA is a classical music station. The University of Houston System owns and holds broadcasting licenses to KUHT, KUHF, and KUHA. The stations broadcast from the Melcher Center for Public Broadcasting, located on the campus of the University of Houston.

Which of Houston's television stations was the first public television station in the U.S.?

Problem: Letter case:

Letter case is often prescribed by the grammar of a language or by the conventions of a particular discipline. In orthography, the uppercase is primarily reserved for special purposes, such as the first letter of a sentence or of a proper noun, which makes the lowercase the more common variant in text. In mathematics, letter case may indicate the relationship between objects with uppercase letters often representing "superior" objects (e.g. X could be a set containing the generic member x). Engineering design drawings are typically labelled entirely in upper-case letters, which are easier to distinguish than lowercase, especially when space restrictions require that the lettering be small.

Which kind of purpose is uppercase reserved for in orthography?

A: special


Problem: Turner Classic Movies:

In December 1994, TCM debuted "TCM Remembers", a tribute to recently deceased notable film personalities (including actors, producers, composers, directors, writers and cinematographers) that occasionally airs during promotional breaks between films. The segments appear in two forms: individual tributes and a longer end-of-year compilation. Following the recent death of an especially famous classic film personality (usually an actor, producer, filmmaker or director), the segment will feature a montage of select shots of the deceased's work. Every December, a longer, more inclusive "TCM Remembers" interstitial is produced that honors all of the noted film personalities who died during the past year, interspersed with scenes from settings such as an abandoned drive-in (2012) or a theatre which is closing down and is being dismantled (2013). Since 2001, the soundtracks for these clipreels have been introspective melodies by indie artists such as Badly Drawn Boy (2007) or Steve Earle (2009).

In what month of the year does a longer version of TCM Remembers appear?

A:
December
