QUES: Traditionally the feast also applied to sexual desires, which were supposed to be suppressed during the following fasting. Before Lent began, all rich food and drink were consumed in what became a giant celebration that involved the whole community, and is thought to be the origin of Carnival. The Lenten period of the Liturgical calendar, the six weeks directly before Easter, was originally marked by fasting and other pious or penitential practices. During Lent, no parties or celebrations were held, and people refrained from eating rich foods, such as meat, dairy, fat and sugar.
What type of rich foods did people refrain from eating during Lent?

ANS: meat, dairy, fat and sugar

QUES: There are technical limitations to archiving a web site, and as a consequence, it is possible for opposing parties in litigation to misuse the results provided by web site archives. This problem can be exacerbated by the practice of submitting screen shots of web pages in complaints, answers, or expert witness reports, when the underlying links are not exposed and therefore, can contain errors. For example, archives such as the Wayback Machine do not fill out forms and therefore, do not include the contents of non-RESTful e-commerce databases in their archives.
What kind of sites contain information that the screen shots do not record?

ANS: unanswerable

QUES: The 10th century saw a mass migration of Turkic tribes from Central Asia into the Iranian plateau. Turkic tribesmen were first used in the Abbasid army as mamluks (slave-warriors), replacing Iranian and Arab elements within the army. As a result, the mamluks gained a significant political power. In 999, large portions of Iran came briefly under the rule of the Ghaznavids, whose rulers were of mamluk Turk origin, and longer subsequently under the Turkish Seljuk and Khwarezmian empires. These Turks had been Persianized and had adopted Persian models of administration and rulership. The Seljuks subsequently gave rise to the Sultanate of Rum in Anatolia, while taking their thoroughly Persianized identity with them. The result of the adoption and patronage of Persian culture by Turkish rulers was the development of a distinct Turko-Persian tradition.
In what year did the Ghaznavids briefly control large portions of Iran?

ANS: 999

QUES: In 1827, Hungarian physicist Ányos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of the continuous rotation with the invention of the commutator, he called his early devices "electromagnetic self-rotors". Although they were used only for instructional purposes, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator. The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windings.
What did Jedlik's improved device eliminate the need for?

ANS:
permanent magnets
