Article: Although the doctrine of Mary's Immaculate Conception appears only later among Latin (and particularly Frankish) theologians, it became ever more manifest among Byzantine theologians reliant on Gregory Nazianzen's Mariology in the Medieval or Byzantine East. Although hymnographers and scholars, like the Emperor Justinian I, were accustomed to call Mary "prepurified" in their poetic and credal statements, the first point of departure for more fully commenting on Nazianzen's meaning occurs in Sophronius of Jerusalem. In other places Sophronius explains that the Theotokos was already immaculate, when she was "purified" at the Annunciation and goes so far as to note that John the Baptist is literally "holier than all 'Men' born of woman" since Mary's surpassing holiness signifies that she was holier than even John after his sanctification in utero. Sophronius' teaching is augmented and incorporated by St. John Damascene (d. 749/750). John, besides many passages wherein he extolls the Theotokos for her purification at the Annunciation, grants her the unique honor of "purifying the waters of baptism by touching them." This honor was most famously and firstly attributed to Christ, especially in the legacy of Nazianzen. As such, Nazianzen's assertion of parallel holiness between the prepurified Mary and purified Jesus of the New Testament is made even more explicit in Damascene in his discourse on Mary's holiness to also imitate Christ's baptism at the Jordan. The Damascene's hymnongraphy and De fide Orthodoxa explicitly use Mary's "pre purification" as a key to understanding her absolute holiness and unsullied human nature. In fact, Damascene (along with Nazianzen) serves as the source for nearly all subsequent promotion of Mary's complete holiness from her Conception by the "all pure seed" of Joachim and the womb "wider than heaven" of St. Ann.

Question: What event happened to Theotokos that was of significant religious note ?
Ans: she was "purified" at the Annunciation


Here is a question about this article: The Greece women's national water polo team have emerged as one of the leading powers in the world, becoming World Champions after their gold medal win against the hosts China at the 2011 World Championship. They have also won the silver medal at the 2004 Summer Olympics, the gold medal at the 2005 World League and the silver medals at the 2010 and 2012 European Championships. The Greece men's national water polo team became the third best water polo team in the world in 2005, after their win against Croatia in the bronze medal game at the 2005 World Aquatics Championships in Canada. The domestic top water polo leagues, Greek Men's Water Polo League and Greek Women's Water Polo League are considered amongst the top national leagues in European water polo, as its clubs have made significant success in European competitions. In men's European competitions, Olympiacos has won the Champions League, the European Super Cup and the Triple Crown in 2002 becoming the first club in Water polo history to win every title in which it has competed within a single year (National championship, National cup, Champions League and European Super Cup), while NC Vouliagmeni has won the LEN Cup Winners' Cup in 1997. In women's European competitions, Greek water polo teams (NC Vouliagmeni, Glyfada NSC, Olympiacos, Ethnikos Piraeus) are amongst the most successful in European water polο, having won as many as 4 LEN Champions Cups, 3 LEN Trophies and 2 European Supercups.
What is the answer to this question: The Greece Men's water polo team held which world ranking in 2005?
****
So... third


The problem: Answer a question about this article:
Scarab beetles held religious and cultural symbolism in Old Egypt, Greece and some shamanistic Old World cultures. The ancient Chinese regarded cicadas as symbols of rebirth or immortality. In Mesopotamian literature, the epic poem of Gilgamesh has allusions to Odonata which signify the impossibility of immortality. Amongst the Aborigines of Australia of the Arrernte language groups, honey ants and witchety grubs served as personal clan totems. In the case of the 'San' bush-men of the Kalahari, it is the praying mantis which holds much cultural significance including creation and zen-like patience in waiting.:9
The praying mantis symbolizes patience and what else?
****
The answer: creation


Problem: Please answer a question about the following article about Electric motor:
In 1886, Frank Julian Sprague invented the first practical DC motor, a non-sparking motor that maintained relatively constant speed under variable loads. Other Sprague electric inventions about this time greatly improved grid electric distribution (prior work done while employed by Thomas Edison), allowed power from electric motors to be returned to the electric grid, provided for electric distribution to trolleys via overhead wires and the trolley pole, and provided controls systems for electric operations. This allowed Sprague to use electric motors to invent the first electric trolley system in 1887–88 in Richmond VA, the electric elevator and control system in 1892, and the electric subway with independently powered centrally controlled cars, which were first installed in 1892 in Chicago by the South Side Elevated Railway where it became popularly known as the "L". Sprague's motor and related inventions led to an explosion of interest and use in electric motors for industry, while almost simultaneously another great inventor was developing its primary competitor, which would become much more widespread. The development of electric motors of acceptable efficiency was delayed for several decades by failure to recognize the extreme importance of a relatively small air gap between rotor and stator. Efficient designs have a comparatively small air gap. [a] The St. Louis motor, long used in classrooms to illustrate motor principles, is extremely inefficient for the same reason, as well as appearing nothing like a modern motor.
What was the name of Chicago's first electric trolley system?
A: South Side Elevated Railway

The art of writing Chinese characters is called Chinese calligraphy. It is usually done with ink brushes. In ancient China, Chinese calligraphy is one of the Four Arts of the Chinese Scholars. There is a minimalist set of rules of Chinese calligraphy. Every character from the Chinese scripts is built into a uniform shape by means of assigning it a geometric area in which the character must occur. Each character has a set number of brushstrokes; none must be added or taken away from the character to enhance it visually, lest the meaning be lost. Finally, strict regularity is not required, meaning the strokes may be accentuated for dramatic effect of individual style. Calligraphy was the means by which scholars could mark their thoughts and teachings for immortality, and as such, represent some of the more precious treasures that can be found from ancient China.

What is one of the Four Arts of the Chinese Scholars?
Answer: Chinese calligraphy
