Problem: Green:

In some languages, including old Chinese, Thai, old Japanese, and Vietnamese, the same word can mean either blue or green. The Chinese character (pronounced qing in Mandarin, ao in Japanese, and thanh in Sino-Vietnamese) has a meaning that covers both blue and green; blue and green are traditionally considered shades of "". In more contemporary terms, they are (lan, in Mandarin) and (lu, in Mandarin) respectively. Japanese also has two terms that refer specifically to the color green, (midori, which is derived from the classical Japanese descriptive verb midoru "to be in leaf, to flourish" in reference to trees) and (guriin, which is derived from the English word "green"). However, in Japan, although the traffic lights have the same colors that other countries have, the green light is described using the same word as for blue, "aoi", because green is considered a shade of aoi; similarly, green variants of certain fruits and vegetables such as green apples, green shiso (as opposed to red apples and red shiso) will be described with the word "aoi". Vietnamese uses a single word for both blue and green, xanh, with variants such as xanh da troi (azure, lit. "sky blue"), lam (blue), and luc (green; also xanh la cay, lit. "leaf green").

Problem: Montana:

Montana schoolchildren played a significant role in selecting several state symbols. The state tree, the ponderosa pine, was selected by Montana schoolchildren as the preferred state tree by an overwhelming majority in a referendum held in 1908. However, the legislature did not designate a state tree until 1949, when the Montana Federation of Garden Clubs, with the support of the state forester, lobbied for formal recognition. Schoolchildren also chose the western meadowlark as the state bird, in a 1930 vote, and the legislature acted to endorse this decision in 1931. Similarly, the secretary of state sponsored a children's vote in 1981 to choose a state animal, and after 74 animals were nominated, the grizzly bear won over the elk by a 21 margin. The students of Livingston started a statewide school petition drive plus lobbied the governor and the state legislature to name the Maiasaura as the state fossil in 1985.

Problem: Gregorian calendar:

The Gregorian reform contained two parts: a reform of the Julian calendar as used prior to Pope Gregory XIII's time and a reform of the lunar cycle used by the Church, with the Julian calendar, to calculate the date of Easter. The reform was a modification of a proposal made by Aloysius Lilius. His proposal included reducing the number of leap years in four centuries from 100 to 97, by making 3 out of 4 centurial years common instead of leap years. Lilius also produced an original and practical scheme for adjusting the epacts of the moon when calculating the annual date of Easter, solving a long-standing obstacle to calendar reform.
