Article: As is known from the "Sumerian Farmer's Almanac", after the flood season and after the Spring Equinox and the Akitu or New Year Festival, using the canals, farmers would flood their fields and then drain the water. Next they made oxen stomp the ground and kill weeds. They then dragged the fields with pickaxes. After drying, they plowed, harrowed, and raked the ground three times, and pulverized it with a mattock, before planting seed. Unfortunately the high evaporation rate resulted in a gradual increase in the salinity of the fields. By the Ur III period, farmers had switched from wheat to the more salt-tolerant barley as their principal crop.

Question: The the Ur III period, what crop had Sumerians switched to from wheat for their primary crop?
Ans: salt-tolerant barley


Article: The majority of studies indicate antibiotics do interfere with contraceptive pills, such as clinical studies that suggest the failure rate of contraceptive pills caused by antibiotics is very low (about 1%). In cases where antibacterials have been suggested to affect the efficiency of birth control pills, such as for the broad-spectrum antibacterial rifampicin, these cases may be due to an increase in the activities of hepatic liver enzymes' causing increased breakdown of the pill's active ingredients. Effects on the intestinal flora, which might result in reduced absorption of estrogens in the colon, have also been suggested, but such suggestions have been inconclusive and controversial. Clinicians have recommended that extra contraceptive measures be applied during therapies using antibacterials that are suspected to interact with oral contraceptives.

Question: What do physicians recommend to counteract this potential issue?
Ans: extra contraceptive measures


Article: There are several technologies aimed to provide better experience to passengers suffering from claustrophobia, anthropophobia or social anxiety. Israeli startup DigiGage uses motion sensors to scroll the pre-rendered images, building and floor-specific content on a screen embedded into the wall as the cab moves up and down. British company LiftEye provides a virtual window technology to turn common elevator into panoramic. It creates 3d video panorama using live feed from cameras placed vertically along the facade and synchronizes it with cab movement. The video is projected on a wall-sized screens making it look like the walls are made of glass.

Question: LiftEye uses virtual window technology for what?
Ans: to turn common elevator into panoramic


Article: Qur'anic schools (also known as dugsi) remain the basic system of traditional religious instruction in Somalia. They provide Islamic education for children, thereby filling a clear religious and social role in the country. Known as the most stable local, non-formal system of education providing basic religious and moral instruction, their strength rests on community support and their use of locally made and widely available teaching materials. The Qur'anic system, which teaches the greatest number of students relative to other educational sub-sectors, is oftentimes the only system accessible to Somalis in nomadic as compared to urban areas. A study from 1993 found, among other things, that "unlike in primary schools where gender disparity is enormous, around 40 per cent of Qur'anic school pupils are girls; but the teaching staff have minimum or no qualification necessary to ensure intellectual development of children." To address these concerns, the Somali government on its own part subsequently established the Ministry of Endowment and Islamic Affairs, under which Qur'anic education is now regulated.

Question: What percentage of students at Qur'anic schools are female?
Ans:
40
