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

CDO issuance grew from an estimated $20 billion in Q1 2004 to its peak of over $180 billion by Q1 2007, then declined back under $20 billion by Q1 2008. Further, the credit quality of CDO's declined from 2000 to 2007, as the level of subprime and other non-prime mortgage debt increased from 5% to 36% of CDO assets. As described in the section on subprime lending, the CDS and portfolio of CDS called synthetic CDO enabled a theoretically infinite amount to be wagered on the finite value of housing loans outstanding, provided that buyers and sellers of the derivatives could be found. For example, buying a CDS to insure a CDO ended up giving the seller the same risk as if they owned the CDO, when those CDO's became worthless.

When did the issuance of CDO peak?

A: Q1 2007


Problem: Studio producers Richard D. Zanuck and David Brown offered Spielberg the director's chair for Jaws, a thriller-horror film based on the Peter Benchley novel about an enormous killer shark. Spielberg has often referred to the gruelling shoot as his professional crucible. Despite the film's ultimate, enormous success, it was nearly shut down due to delays and budget over-runs. But Spielberg persevered and finished the film. It was an enormous hit, winning three Academy Awards (for editing, original score and sound) and grossing more than $470 million worldwide at the box office. It also set the domestic record for box office gross, leading to what the press described as "Jawsmania.":248 Jaws made Spielberg a household name and one of America's youngest multi-millionaires, allowing him a great deal of autonomy for his future projects.:250 It was nominated for Best Picture and featured Spielberg's first of three collaborations with actor Richard Dreyfuss.
How much money did the film "Jaws" gross worldwide?

Question: Zinc is an essential mineral perceived by the public today as being of "exceptional biologic and public health importance", especially regarding prenatal and postnatal development. Zinc deficiency affects about two billion people in the developing world and is associated with many diseases. In children it causes growth retardation, delayed sexual maturation, infection susceptibility, and diarrhea. Enzymes with a zinc atom in the reactive center are widespread in biochemistry, such as alcohol dehydrogenase in humans. Consumption of excess zinc can cause ataxia, lethargy and copper deficiency.
Is there an answer to this question: In what substance can you find a zinc atom within its reactive center?

Answer: alcohol dehydrogenase
