Problem: Time:

Einstein showed in his thought experiments that people travelling at different speeds, while agreeing on cause and effect, measure different time separations between events, and can even observe different chronological orderings between non-causally related events. Though these effects are typically minute in the human experience, the effect becomes much more pronounced for objects moving at speeds approaching the speed of light. Many subatomic particles exist for only a fixed fraction of a second in a lab relatively at rest, but some that travel close to the speed of light can be measured to travel farther and survive much longer than expected (a muon is one example). According to the special theory of relativity, in the high-speed particle's frame of reference, it exists, on the average, for a standard amount of time known as its mean lifetime, and the distance it travels in that time is zero, because its velocity is zero. Relative to a frame of reference at rest, time seems to "slow down" for the particle. Relative to the high-speed particle, distances seem to shorten. Einstein showed how both temporal and spatial dimensions can be altered (or "warped") by high-speed motion.

Einstein showed how what could be altered by fixed particles?

Problem: War on Terror:

Following the ceasefire agreement that suspended hostilities (but not officially ended) in the 1991 Gulf War, the United States and its allies instituted and began patrolling Iraqi no-fly zones, to protect Iraq's Kurdish and Shi'a Arab populationboth of which suffered attacks from the Hussein regime before and after the Gulf Warin Iraq's northern and southern regions, respectively. U.S. forces continued in combat zone deployments through November 1995 and launched Operation Desert Fox against Iraq in 1998 after it failed to meet U.S. demands of "unconditional cooperation" in weapons inspections.

What was instituted to protect Iraq's Arab and Shi'a Kurdish population?

Problem: Bermuda:

Bermuda's modern black population contains more than one demographic group. Although the number of residents born in Africa is very small, it has tripled between 2000 and 2010 (this group also includes non-blacks). The majority of blacks in Bermuda can be termed "Bermudian blacks", whose ancestry dates back centuries between the 17th century and the end of slavery in 1834, Bermuda's black population was self-sustaining, with its growth resulting largely from natural expansion. This contrasts to the enslaved blacks of the plantation colonies, who were subjected to conditions so harsh as to drop their birth rate below the death rate, and slaveholders in the United States and the West Indies found it necessary to continue importing more enslaved blacks from Africa until the end of slavery (the same had been true for the Native Americans that the Africans had replaced on the New World plantations). The indigenous populations of many West Indian islands, and much of the South-East of what is now the United States that had survived the 16th- and 17th-century epidemics of European-introduced diseases then became the victims of large-scale slave raiding, with much of the region completely depopulated. When the supply of indigenous slaves ran out, the slaveholders looked to Africa). The ancestry of Bermuda's black population is distinguished from that of the British West Indian black population in two ways: firstly, the higher degree of European and Native American admixture; secondly, the source of the African ancestry.

What is one way that the ancestry of Bermudian black population differs from that of British West Indian black population?
---
A: the source of the African ancestry

Problem: Georgian architecture:

Versions of revived Palladian architecture dominated English country house architecture. Houses were increasingly placed in grand landscaped settings, and large houses were generally made wide and relatively shallow, largely to look more impressive from a distance. The height was usually highest in the centre, and the Baroque emphasis on corner pavilions often found on the continent generally avoided. In grand houses, an entrance hall led to steps up to a piano nobile or mezzanine floor where the main reception rooms were. Typically the basement area or "rustic", with kitchens, offices and service areas, as well as male guests with muddy boots, came some way above ground, and was lit by windows that were high on the inside, but just above ground level outside. A single block was typical, with a perhaps a small court for carriages at the front marked off by railings and a gate, but rarely a stone gatehouse, or side wings around the court.

What was done to make houses look more impressive from close-up?
