Problem: Gregorian calendar:

Lilius's proposals had two components. Firstly, he proposed a correction to the length of the year. The mean tropical year is 365.24219 days long. As the average length of a Julian year is 365.25 days, the Julian year is almost 11 minutes longer than the mean tropical year. The discrepancy results in a drift of about three days every 400 years. Lilius's proposal resulted in an average year of 365.2425 days (see Accuracy). At the time of Gregory's reform there had already been a drift of 10 days since the Council of Nicaea, resulting in the vernal equinox falling on 10 or 11 March instead of the ecclesiastically fixed date of 21 March, and if unreformed it would drift further. Lilius proposed that the 10-day drift should be corrected by deleting the Julian leap day on each of its ten occurrences over a period of forty years, thereby providing for a gradual return of the equinox to 21 March.

What did Gregory propose deleting to correct the ten day drift?

A: unanswerable


Problem: Pesticide:

Some evidence shows that alternatives to pesticides can be equally effective as the use of chemicals. For example, Sweden has halved its use of pesticides with hardly any reduction in crops.[unreliable source?] In Indonesia, farmers have reduced pesticide use on rice fields by 65% and experienced a 15% crop increase.[unreliable source?] A study of Maize fields in northern Florida found that the application of composted yard waste with high carbon to nitrogen ratio to agricultural fields was highly effective at reducing the population of plant-parasitic nematodes and increasing crop yield, with yield increases ranging from 10% to 212%; the observed effects were long-term, often not appearing until the third season of the study.

What natural substance has been found to effectively increase crop yields
---
A: carbon to nitrogen


Problem: Department store:

Although there were a number of department stores in Australia for much of the 20th Century, including chains such as Grace Bros. and Waltons, many disappeared during the 1980s and 1990s. Today Myer and David Jones, located nationally, are practically the national department stores duopoly in Australia. When Russian-born migrant, Sidney Myer, came to Australia in 1899 he formed the Myer retail group with his brother, Elcon Myer. In 1900, they opened the first Myer department store, in Bendigo, Victoria. Since then, the Myer retail group has grown to be Australia's largest retailer. Both, Myer and David Jones, are up-market chains, offering a wide variety of products from mid-range names to luxury brands. Other retail chain stores such as Target (unrelated to the American chain of the same name), Venture (now defunct), Kmart and Big W, also located nationally, are considered to be Australia's discount department stores. Harris Scarfe, though only operating in four states and one territory, is a department store using both the large full-line and small discount department store formats. Most department stores in Australia have their own credit card companies, each having their own benefits while the discount department stores do not have their own credit card rights.

What department store brand is now out of business in Australia?

A: Venture


Problem: Canon law:

Much of the legislative style was adapted from the Roman Law Code of Justinian. As a result, Roman ecclesiastical courts tend to follow the Roman Law style of continental Europe with some variation, featuring collegiate panels of judges and an investigative form of proceeding, called "inquisitorial", from the Latin "inquirere", to enquire. This is in contrast to the adversarial form of proceeding found in the common law system of English and U.S. law, which features such things as juries and single judges.

What word characterizes the type of procedure found in American and British courts?
---
A:
adversarial
