Problem: Child labour:

Many factors played a role in Britain's long-term economic growth, such as the industrial revolution in the late 1700s and the prominent presence of child labour during the industrial age. Children who worked at an early age were often not forced; but did so because they needed to help their family survive financially. Due to poor employment opportunities for many parents, sending their children to work on farms and in factories was a way to help feed and support the family. Child Labour first started to occur in England when household businesses were turned into local labour markets that mass-produced the once homemade goods. Because children often helped produce the goods out of their homes, working in a factory to make those same goods was a simple change for many of these youths. Although there are many counts of children under the age of ten working for factories, the majority of children workers were between the ages of ten and fourteen. This age range was an important time for many youths as they were first helping to provide for their families; while also transitioning to save for their own future families.

Problem: United States Air Force:

The first USAF dress uniform, in 1947, was dubbed and patented "Uxbridge Blue" after "Uxbridge 1683 Blue", developed at the former Bachman-Uxbridge Worsted Company. The current Service Dress Uniform, which was adopted in 1993 and standardized in 1995, consists of a three-button, pocketless coat, similar to that of a men's "sport jacket" (with silver "U.S." pins on the lapels, with a silver ring surrounding on those of enlisted members), matching trousers, and either a service cap or flight cap, all in Shade 1620, "Air Force Blue" (a darker purplish-blue). This is worn with a light blue shirt (Shade 1550) and Shade 1620 herringbone patterned necktie. Enlisted members wear sleeve insignia on both the jacket and shirt, while officers wear metal rank insignia pinned onto the coat, and Air Force Blue slide-on epaulet loops on the shirt. USAF personnel assigned to Base Honor Guard duties wear, for certain occasions, a modified version of the standard service dress uniform, but with silver trim on the sleeves and trousers, with the addition of a ceremonial belt (if necessary), wheel cap with silver trim and Hap Arnold Device, and a silver aiguillette placed on the left shoulder seam and all devices and accoutrement.

Where was the Uxbridge Blue dress uniform developed?

Problem: Neptune:

Models suggest that Neptune's troposphere is banded by clouds of varying compositions depending on altitude. The upper-level clouds lie at pressures below one bar, where the temperature is suitable for methane to condense. For pressures between one and five bars (100 and 500 kPa), clouds of ammonia and hydrogen sulfide are thought to form. Above a pressure of five bars, the clouds may consist of ammonia, ammonium sulfide, hydrogen sulfide and water. Deeper clouds of water ice should be found at pressures of about 50 bars (5.0 MPa), where the temperature reaches 273 K (0 C). Underneath, clouds of ammonia and hydrogen sulfide may be found.

What is the temperature on Neptune's clouds that are at 50 bars?

A: 273 K (0 C)

Problem: Saint Barth%C3%A9lemy:

The island covers an area of 25 square kilometres (2,500 ha). The eastern side is wetter than the western. Although the climate is essentially arid, the rainfall does average 1000 mm annually, but with considerable variation over the terrain. Summer is from May to November, which is also the rainy season. Winter from December to April is the dry season. Sunshine is very prominent for nearly the entire year and even during the rainy season. Humidity, however, is not very high due to the winds. The average temperature is around 25 C with day temperatures rising to 32 C. The average high and low temperatures in January are 28 C and 22 C, respectively, while in July they are 30 C and 24 C. The lowest night temperature recorded is 13 C. The Caribbean sea waters in the vicinity generally maintain a temperature of about 27 C.

What type of climate does St. Barts typically have?
---
A:
arid
