Extract the answer to the question from the following context. Question: What is more resilient? Context: For a variety of reasons, market participants did not accurately measure the risk inherent with financial innovation such as MBS and CDOs or understand its impact on the overall stability of the financial system. For example, the pricing model for CDOs clearly did not reflect the level of risk they introduced into the system. Banks estimated that $450bn of CDO were sold between "late 2005 to the middle of 2007"; among the $102bn of those that had been liquidated, JPMorgan estimated that the average recovery rate for "high quality" CDOs was approximately 32 cents on the dollar, while the recovery rate for mezzanine CDO was approximately five cents for every dollar.

[Q]: Extract the answer to the question from the following context. Question: What kind of devices are examples of this? Context: Some USB devices require more power than is permitted by the specifications for a single port. This is common for external hard and optical disc drives, and generally for devices with motors or lamps. Such devices can use an external power supply, which is allowed by the standard, or use a dual-input USB cable, one input of which is used for power and data transfer, the other solely for power, which makes the device a non-standard USB device. Some USB ports and external hubs can, in practice, supply more power to USB devices than required by the specification but a standard-compliant device may not depend on this.

[A]: external hard and optical disc drives

Extract the answer to the question from the following context. Question: What was the hiding place of the guerrillas? Context: On 30 September, Zhou Enlai warned the United States that China was prepared to intervene in Korea if the United States crossed the 38th parallel. Zhou attempted to advise North Korean commanders on how to conduct a general withdrawal by using the same tactics which had allowed Chinese communist forces to successfully escape Chiang Kai-shek's Encirclement Campaigns in the 1930s, but by some accounts North Korean commanders did not utilize these tactics effectively. Historian Bruce Cumings argues, however, the KPA's rapid withdrawal was strategic, with troops melting into the mountains from where they could launch guerrilla raids on the UN forces spread out on the coasts.
