Input: Mandolin
In his 1805 mandolin method, Anweisung die Mandoline von selbst zu erlernen nebst einigen Uebungsstucken von Bortolazzi, Bartolomeo Bortolazzi popularised the Cremonese mandolin, which had four single-strings and a fixed bridge, to which the strings were attached. Bortolazzi said in this book that the new wire strung mandolins were uncomfortable to play, when compared with the gut-string instruments. Also, he felt they had a "less pleasing...hard, zither-like tone" as compared to the gut string's "softer, full-singing tone." He favored the four single strings of the Cremonese instrument, which were tuned the same as the Neapolitan.

Did Bortolazzi like playing the new wire strung mandolins?
Output: uncomfortable to play

Input: Tucson, Arizona
Jesuit missionary Eusebio Francisco Kino visited the Santa Cruz River valley in 1692, and founded the Mission San Xavier del Bac in 1700 about 7 mi (11 km) upstream from the site of the settlement of Tucson. A separate Convento settlement was founded downstream along the Santa Cruz River, near the base of what is now "A" mountain. Hugo O'Conor, the founding father of the city of Tucson, Arizona authorized the construction of a military fort in that location, Presidio San Agustin del Tucson, on August 20, 1775 (near the present downtown Pima County Courthouse). During the Spanish period of the presidio, attacks such as the Second Battle of Tucson were repeatedly mounted by Apaches. Eventually the town came to be called "Tucson" and became a part of Sonora after Mexico gained independence from Spain in 1821.

What year did Mexico gain independence from Spain?
Output: 1821

Input: Energy
Matter may be converted to energy (and vice versa), but mass cannot ever be destroyed; rather, mass/energy equivalence remains a constant for both the matter and the energy, during any process when they are converted into each other. However, since is extremely large relative to ordinary human scales, the conversion of ordinary amount of matter (for example, 1 kg) to other forms of energy (such as heat, light, and other radiation) can liberate tremendous amounts of energy (~ joules = 21 megatons of TNT), as can be seen in nuclear reactors and nuclear weapons. Conversely, the mass equivalent of a unit of energy is minuscule, which is why a loss of energy (loss of mass) from most systems is difficult to measure by weight, unless the energy loss is very large. Examples of energy transformation into matter (i.e., kinetic energy into particles with rest mass) are found in high-energy nuclear physics.

Why is a loss of energy difficult to measure by weight?
Output: mass equivalent of a unit of energy is minuscule

Input: Financial crisis of 2007%E2%80%9308
IndyMac reported that during April 2008, Moody's and Standard & Poor's downgraded the ratings on a significant number of Mortgage-backed security (MBS) bonds including $160 million of those issued by IndyMac and which the bank retained in its MBS portfolio. IndyMac concluded that these downgrades would have negatively impacted the Company's risk-based capital ratio as of June 30, 2008. Had these lowered ratings been in effect at March 31, 2008, IndyMac concluded that the bank's capital ratio would have been 9.27% total risk-based. IndyMac warned that if its regulators found its capital position to have fallen below "well capitalized" (minimum 10% risk-based capital ratio) to "adequately capitalized" (810% risk-based capital ratio) the bank might no longer be able to use brokered deposits as a source of funds.

If IndyMac's downgraded MBS bond ratings had been in effect at March 31, 2008, what would the bank's capital ratio have been?
Output:
9.27%
