Problem: Pope John XXIII:

Maintaining continuity with his predecessors, John XXIII continued the gradual reform of the Roman liturgy, and published changes that resulted in the 1962 Roman Missal, the last typical edition containing the Tridentine Mass established in 1570 by Pope Pius V at the request of the Council of Trent and whose continued use Pope Benedict XVI authorized in 2007, under the conditions indicated in his motu proprio Summorum Pontificum. In response to the directives of the Second Vatican Council, later editions of the Roman Missal present the 1970 form of the Roman Rite.

What did Pope Benedict XVI continue the gradual reform of?

A: unanswerable

Problem: Religion in ancient Rome:

Other public festivals were not required by the calendar, but occasioned by events. The triumph of a Roman general was celebrated as the fulfillment of religious vows, though these tended to be overshadowed by the political and social significance of the event. During the late Republic, the political elite competed to outdo each other in public display, and the ludi attendant on a triumph were expanded to include gladiator contests. Under the Principate, all such spectacular displays came under Imperial control: the most lavish were subsidised by emperors, and lesser events were provided by magistrates as a sacred duty and privilege of office. Additional festivals and games celebrated Imperial accessions and anniversaries. Others, such as the traditional Republican Secular Games to mark a new era (saeculum), became imperially funded to maintain traditional values and a common Roman identity. That the spectacles retained something of their sacral aura even in late antiquity is indicated by the admonitions of the Church Fathers that Christians should not take part.

Who paid for the most lavish of festival events?
---
A: emperors

Problem: Capacitor:

Electrolytic capacitors use an aluminum or tantalum plate with an oxide dielectric layer. The second electrode is a liquid electrolyte, connected to the circuit by another foil plate. Electrolytic capacitors offer very high capacitance but suffer from poor tolerances, high instability, gradual loss of capacitance especially when subjected to heat, and high leakage current. Poor quality capacitors may leak electrolyte, which is harmful to printed circuit boards. The conductivity of the electrolyte drops at low temperatures, which increases equivalent series resistance. While widely used for power-supply conditioning, poor high-frequency characteristics make them unsuitable for many applications. Electrolytic capacitors will self-degrade if unused for a period (around a year), and when full power is applied may short circuit, permanently damaging the capacitor and usually blowing a fuse or causing failure of rectifier diodes (for instance, in older equipment, arcing in rectifier tubes). They can be restored before use (and damage) by gradually applying the operating voltage, often done on antique vacuum tube equipment over a period of 30 minutes by using a variable transformer to supply AC power. Unfortunately, the use of this technique may be less satisfactory for some solid state equipment, which may be damaged by operation below its normal power range, requiring that the power supply first be isolated from the consuming circuits. Such remedies may not be applicable to modern high-frequency power supplies as these produce full output voltage even with reduced input.

What is one type of metal which the conducting plates in electrolytic capacitors are never made of?
---
A: unanswerable

Problem: Genome:

It had been found that the proportion of non-repetitive DNA can vary a lot between species. Some E. coli as prokaryotes only have non-repetitive DNA, lower eukaryotes such as C. elegans and fruit fly, still possess more non-repetitive DNA than repetitive DNA. Higher eukaryotes tend to have more repetitive DNA than non-repetitive ones. In some plants and amphibians, the proportion of non-repetitive DNA is no more than 20%, becoming a minority component.

What is an example of an organism which does not contain any repetitive DNA?
---
A:
E. coli
