Problem: CBC Television:

The CBC's flagship newscast, The National, airs Sunday through Fridays at 10:00 p.m. EST and Saturdays at 6:00 p.m. EST. Until October 2006, CBC owned-and-operated stations aired a second broadcast of the program at 11:00 p.m.; this later broadcast included only the main news portion of the program, and excluded the analysis and documentary segment. This second airing was later replaced with other programming, and as of the 2012-13 television season, was replaced on CBC's major market stations by a half-hour late newscast. There is also a short news update, at most, on late Saturday evenings. During hockey season, this update is usually found during the first intermission of the second game of the doubleheader on Hockey Night in Canada.

Problem: Financial crisis of 2007%E2%80%9308:

Rapid increases in a number of commodity prices followed the collapse in the housing bubble. The price of oil nearly tripled from $50 to $147 from early 2007 to 2008, before plunging as the financial crisis began to take hold in late 2008. Experts debate the causes, with some attributing it to speculative flow of money from housing and other investments into commodities, some to monetary policy, and some to the increasing feeling of raw materials scarcity in a fast-growing world, leading to long positions taken on those markets, such as Chinese increasing presence in Africa. An increase in oil prices tends to divert a larger share of consumer spending into gasoline, which creates downward pressure on economic growth in oil importing countries, as wealth flows to oil-producing states. A pattern of spiking instability in the price of oil over the decade leading up to the price high of 2008 has been recently identified. The destabilizing effects of this price variance has been proposed as a contributory factor in the financial crisis.

Following the collapse in the housing bubble, what happened to a number of commodity prices?
---
A: Rapid increases


Problem: Pope Paul VI:

Cardinal Augustin Bea, the head of the Secretariat for Promoting Christian Unity, added at the end of the visit, "Let us move forward in Christ. God wants it. Humanity is waiting for it." Unmoved by a harsh condemnation by the Congregation of Faith on mixed marriages precisely at this time of the visit, Paul VI and Ramsey appointed a preparatory commission which was to put the common agenda into practice on such issues as mixed marriages. This resulted in a joint Malta declaration, the first joint agreement on the Creed since the Reformation. Paul VI was a good friend of the Anglican Church, which he described as "our beloved sister Church". This description was unique to Paul and not used by later popes.

What did the Cardinal Augustin Bea's Secretariat promote?
---
A:
Christian Unity
