Problem: Please answer a question about the following article about Capacitor:
Several other types of capacitor are available for specialist applications. Supercapacitors store large amounts of energy. Supercapacitors made from carbon aerogel, carbon nanotubes, or highly porous electrode materials, offer extremely high capacitance (up to 5 kF as of 2010[update]) and can be used in some applications instead of rechargeable batteries. Alternating current capacitors are specifically designed to work on line (mains) voltage AC power circuits. They are commonly used in electric motor circuits and are often designed to handle large currents, so they tend to be physically large. They are usually ruggedly packaged, often in metal cases that can be easily grounded/earthed. They also are designed with direct current breakdown voltages of at least five times the maximum AC voltage.
How many times the maximum AC voltage are AC capacitors designed to withstand?
A: at least five times the maximum AC voltage

Question: Read this and answer the question

In the classical era, several ancient city-states such as Opone, Essina, Sarapion, Nikon, Malao, Damo and Mosylon near Cape Guardafui, which competed with the Sabaeans, Parthians and Axumites for the wealthy Indo-Greco-Roman trade, also flourished in Somalia.

What trade did the ancient Somalis and others compete for?
Answer: Indo-Greco-Roman

Problem: In Canada, the Royal Newfoundland Constabulary was founded in 1729, making it the first police force in present-day Canada. It was followed in 1834 by the Toronto Police, and in 1838 by police forces in Montreal and Quebec City. A national force, the Dominion Police, was founded in 1868. Initially the Dominion Police provided security for parliament, but its responsibilities quickly grew. The famous Royal Northwest Mounted Police was founded in 1873. The merger of these two police forces in 1920 formed the world-famous Royal Canadian Mounted Police.
When was the Toronto police created?
The answer is the following: 1834

Many[who?] expected BSkyB to make a bid to show some of the remaining FA Cup games for the remainder of the 200910 season which would include a semi-final and shared rights to the final. ESPN took over the package Setanta held for the FA Cup from the 201011 season. The 2011 final was also shown live on Sky 3D in addition to ESPN (who provided the 3D coverage for Sky 3D) and ITV. Following the sale of ESPN's UK and Ireland channels to BT, ESPN's rights package transferred to BT Sport from the 201314 season.
Who took over after ESPN?
BT Sport

Input: Race (human categorization)
Mass incarceration in the United States disproportionately impacts African American and Latino communities. Michelle Alexander, author of The New Jim Crow: Mass Incarceration in the Age of Colorblindness (2010), argues that mass incarceration is best understood as not only a system of overcrowded prisons. Mass incarceration is also, "the larger web of laws, rules, policies, and customs that control those labeled criminals both in and out of prison." She defines it further as "a system that locks people not only behind actual bars in actual prisons, but also behind virtual bars and virtual walls", illustrating the second-class citizenship that is imposed on a disproportionate number of people of color, specifically African-Americans. She compares mass incarceration to Jim Crow laws, stating that both work as racial caste systems.

Who does Alexander think a second class citizenship is imposed upon disproportionately?
Output: people of color

Problem: Please answer a question about the following article about 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.
What was the estimated value of CDO issuance in Q1 2008?
A:
under $20 billion
