Problem: Lighting:

Vehicles typically include headlamps and tail lights. Headlamps are white or selective yellow lights placed in the front of the vehicle, designed to illuminate the upcoming road and to make the vehicle more visible. Many manufactures are turning to LED headlights as an energy-efficient alternative to traditional headlamps. Tail and brake lights are red and emit light to the rear so as to reveal the vehicle's direction of travel to following drivers. White rear-facing reversing lamps indicate that the vehicle's transmission has been placed in the reverse gear, warning anyone behind the vehicle that it is moving backwards, or about to do so. Flashing turn signals on the front, side, and rear of the vehicle indicate an intended change of position or direction. In the late 1950s, some automakers began to use electroluminescent technology to backlight their cars' speedometers and other gauges or to draw attention to logos or other decorative elements.

What color are tail lights?

Melbourne has an integrated public transport system based around extensive train, tram, bus and taxi systems. Flinders Street Station was the world's busiest passenger station in 1927 and Melbourne's tram network overtook Sydney's to become the world's largest in the 1940s, at which time 25% of travellers used public transport but by 2003 it had declined to just 7.6%. The public transport system was privatised in 1999, symbolising the peak of the decline. Despite privatisation and successive governments persisting with auto-centric urban development into the 21st century, there have since been large increases in public transport patronage, with the mode share for commuters increasing to 14.8% and 8.4% of all trips. A target of 20% public transport mode share for Melbourne by 2020 was set by the state government in 2006. Since 2006 public transport patronage has grown by over 20%.
In 2003, what percentage of travellers used public transport?
A: 7.6%

Context and question: The Valencia Cathedral was called Iglesia Mayor in the early days of the Reconquista, then Iglesia de la Seo (Seo is from the Latin sedes, i.e., (archiepiscopal) See), and by virtue of the papal concession of 16 October 1866, it was called the Basilica Metropolitana. It is situated in the centre of the ancient Roman city where some believe the temple of Diana stood. In Gothic times, it seems to have been dedicated to the Holy Saviour; the Cid dedicated it to the Blessed Virgin; King James I of Aragon did likewise, leaving in the main chapel the image of the Blessed Virgin, which he carried with him and is reputed to be the one now preserved in the sacristy. The Moorish mosque, which had been converted into a Christian Church by the conqueror, was deemed unworthy of the title of the cathedral of Valencia, and in 1262 Bishop Andres de Albalat laid the cornerstone of the new Gothic building, with three naves; these reach only to the choir of the present building. Bishop Vidal de Blanes built the chapter hall, and James I added the tower, called El Miguelete because it was blessed on St. Michael's day in 1418. The tower is about 58 m high and topped with a belfry (16601736).
How tall is the cathedral's tower?
Answer: 58 m

Question: Feminist anthropology is a four field approach to anthropology (archeological, biological, cultural, linguistic) that seeks to reduce male bias in research findings, anthropological hiring practices, and the scholarly production of knowledge. Anthropology engages often with feminists from non-Western traditions, whose perspectives and experiences can differ from those of white European and American feminists. Historically, such 'peripheral' perspectives have sometimes been marginalized and regarded as less valid or important than knowledge from the western world. Feminist anthropologists have claimed that their research helps to correct this systematic bias in mainstream feminist theory. Feminist anthropologists are centrally concerned with the construction of gender across societies. Feminist anthropology is inclusive of birth anthropology as a specialization.
Is there an answer to this question: Who's experiences are similar to white European and American feminists?

Answer: unanswerable

By 1840, the Market Hall and Sheds, where fresh meat and produce were brought daily, became a hub of commercial activity. The slave trade also depended on the port of Charleston, where ships could be unloaded and the slaves bought and sold. The legal importation of African slaves had ended in 1808, although smuggling was significant. However, the domestic trade was booming. More than one million slaves were transported from the Upper South to the Deep South in the antebellum years, as cotton plantations were widely developed through what became known as the Black Belt. Many slaves were transported in the coastwise slave trade, with slave ships stopping at ports such as Charleston.
What year did the legal importation of slaves start?
A:
unanswerable
