Islamic architecture used mosaic technique to decorate religious buildings and palaces after the Muslim conquests of the eastern provinces of the Byzantine Empire. In Syria and Egypt the Arabs were influenced by the great tradition of Roman and Early Christian mosaic art. During the Umayyad Dynasty mosaic making remained a flourishing art form in Islamic culture and it is continued in the art of zellige and azulejo in various parts of the Arab world, although tile was to become the main Islamic form of wall decoration.
In Syria and Egypt, other than early Christians, who influenced their mosaic work?
****
The answer: Roman

The U.S. Census Bureau reports a 2010 population of 129,779, with 47,094 households and 25,854 families within the city of New Haven. The population density is 6,859.8 people per square mile (2,648.6/km). There are 52,941 housing units at an average density of 2,808.5 per square mile (1,084.4/km). The racial makeup of the city is 42.6% White, 35.4% African American, 0.5% Native American, 4.6% Asian, 0.1% Pacific Islander, 12.9% from other races, and 3.9% from two or more races. Hispanic or Latino residents of any race were 27.4% of the population. Non-Hispanic Whites were 31.8% of the population in 2010, down from 69.6% in 1970. The city's demography is shifting rapidly: New Haven has always been a city of immigrants and currently the Latino population is growing rapidly. Previous influxes among ethnic groups have been African-Americans in the postwar era, and Irish, Italian and (to a lesser degree) Slavic peoples in the prewar period.
What is the total population of New Haven as reported by the U.S. Census Bureau in 2010?
****
The answer: 129,779

Apple announced a battery replacement program on November 14, 2003, a week before a high publicity stunt and website by the Neistat Brothers. The initial cost was US$99, and it was lowered to US$59 in 2005. One week later, Apple offered an extended iPod warranty for US$59. For the iPod Nano, soldering tools are needed because the battery is soldered onto the main board. Fifth generation iPods have their battery attached to the backplate with adhesive.
What generation saw iPod batterys being affixed with glue?
****
The answer: Fifth generation

The problem: Answer a question about this article:
Polarization is the sum of the E-plane orientations over time projected onto an imaginary plane perpendicular to the direction of motion of the radio wave. In the most general case, polarization is elliptical, meaning that the polarization of the radio waves varies over time. Two special cases are linear polarization (the ellipse collapses into a line) as we have discussed above, and circular polarization (in which the two axes of the ellipse are equal). In linear polarization the electric field of the radio wave oscillates back and forth along one direction; this can be affected by the mounting of the antenna but usually the desired direction is either horizontal or vertical polarization. In circular polarization, the electric field (and magnetic field) of the radio wave rotates at the radio frequency circularly around the axis of propagation. Circular or elliptically polarized radio waves are designated as right-handed or left-handed using the "thumb in the direction of the propagation" rule. Note that for circular polarization, optical researchers use the opposite right hand rule from the one used by radio engineers.
What is the name to describe polarization of radio waves varies over times?
****
The answer:
elliptical
