Problem: Uranium:

Salts of many oxidation states of uranium are water-soluble and may be studied in aqueous solutions. The most common ionic forms are U3+ (brown-red), U4+ (green), UO+
2 (unstable), and UO2+
2 (yellow), for U(III), U(IV), U(V), and U(VI), respectively. A few solid and semi-metallic compounds such as UO and US exist for the formal oxidation state uranium(II), but no simple ions are known to exist in solution for that state. Ions of U3+ liberate hydrogen from water and are therefore considered to be highly unstable. The UO2+
2 ion represents the uranium(VI) state and is known to form compounds such as uranyl carbonate, uranyl chloride and uranyl sulfate. UO2+
2 also forms complexes with various organic chelating agents, the most commonly encountered of which is uranyl acetate.

Along with uranyl sulfate and uranyl chloride, what compound isn't formed by the UO2+ 2 ion?

A: unanswerable


Problem: In 2001, Comcast announced it would acquire the assets of the largest cable television operator at the time, AT&T Broadband, for US$44.5 billion. The proposed name for the merged company was "AT&T Comcast", but the companies ultimately decided to keep only the Comcast name. In 2002, Comcast acquired all assets of AT&T Broadband, thus making Comcast the largest cable television company in the United States with over 22 million subscribers. This also spurred the start of Comcast Advertising Sales (using AT&T's groundwork) which would later be renamed Comcast Spotlight. As part of this acquisition, Comcast also acquired the National Digital Television Center in Centennial, Colorado as a wholly owned subsidiary, which is today known as the Comcast Media Center.
Comcast's advertising and commercial production branch was called what?

Answer: Comcast Spotlight

As of the April 15 filing, LaRouche had 7834 individual contributions, of those who have given cumulatively, $200 or more, as compared to 6257 for John Kerry, 5582 for John Edwards, 4090 for Howard Dean, and 2744 for Gephardt.

Context and question: 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?
Answer: December
