The London Centre for Nanotechnology was established in the same year as a joint venture between UCL and Imperial College London. In 2004 the Tanaka Business School (now named the Imperial College Business School) and a new Main Entrance on Exhibition Road were opened by The Queen. The UK Energy Research Centre was also established in 2004 and opened its headquarters at Imperial College. In November 2005 the Faculties of Life Sciences and Physical Sciences merged to become the Faculty of Natural Sciences.
Question: When did the Privy Council give Imperial an award?

Output: unanswerable

Input: Read this: Economist Mark Zandi testified to the Financial Crisis Inquiry Commission in January 2010: "The securitization markets also remain impaired, as investors anticipate more loan losses. Investors are also uncertain about coming legal and accounting rule changes and regulatory reforms. Private bond issuance of residential and commercial mortgage-backed securities, asset-backed securities, and CDOs peaked in 2006 at close to $2 trillion...In 2009, private issuance was less than $150 billion, and almost all of it was asset-backed issuance supported by the Federal Reserve's TALF program to aid credit card, auto and small-business lenders. Issuance of residential and commercial mortgage-backed securities and CDOs remains dormant."
Question: What was the value of CDOs at their peak in 2006?

Output: close to $2 trillion

Input: Read this: Some paleontologists suggest that animals appeared much earlier than the Cambrian explosion, possibly as early as 1 billion years ago. Trace fossils such as tracks and burrows found in the Tonian period indicate the presence of triploblastic worms, like metazoans, roughly as large (about 5 mm wide) and complex as earthworms. During the beginning of the Tonian period around 1 billion years ago, there was a decrease in Stromatolite diversity, which may indicate the appearance of grazing animals, since stromatolite diversity increased when grazing animals went extinct at the End Permian and End Ordovician extinction events, and decreased shortly after the grazer populations recovered. However the discovery that tracks very similar to these early trace fossils are produced today by the giant single-celled protist Gromia sphaerica casts doubt on their interpretation as evidence of early animal evolution.
Question: How long ago do some paleontologists believe that animals first appeared?

Output: 1 billion years
