Input: Consider Input: In 1584, Elizabeth I granted a charter to Sir Walter Raleigh, for whom the state capital is named, for land in present-day North Carolina (then part of the territory of Virginia). It was the second American territory which the English attempted to colonize. Raleigh established two colonies on the coast in the late 1580s, but both failed. The fate of the "Lost Colony" of Roanoke Island remains one of the most widely debated mysteries of American history. Virginia Dare, the first English child to be born in North America, was born on Roanoke Island on August 18, 1587; Dare County is named for her.

Output: Who is the North Carolina state capital named for?


Input: Consider Input: Advances were made in irrigation and farming, using new technology such as the windmill. Crops such as almonds and citrus fruit were brought to Europe through al-Andalus, and sugar cultivation was gradually adopted by the Europeans. Arab merchants dominated trade in the Indian Ocean until the arrival of the Portuguese in the 16th century. Hormuz was an important center for this trade. There was also a dense network of trade routes in the Mediterranean, along which Muslim countries traded with each other and with European powers such as Venice, Genoa and Catalonia. The Silk Road crossing Central Asia passed through Muslim states between China and Europe.

Output: which crops were brought to europe from the Muslim World?


Input: Consider Input: In British English, the word 'asphalt' is used to refer to a mixture of mineral aggregate and asphalt/bitumen (also called tarmac in common parlance). When bitumen is mixed with clay it is usually called asphaltum. The earlier word 'asphaltum' is now archaic and not commonly used.[citation needed] In American English, 'asphalt' is equivalent to the British 'bitumen'. However, 'asphalt' is also commonly used as a shortened form of 'asphalt concrete' (therefore equivalent to the British 'asphalt' or 'tarmac'). In Australian English, bitumen is often used as the generic term for road surfaces. In Canadian English, the word bitumen is used to refer to the vast Canadian deposits of extremely heavy crude oil, while asphalt is used for the oil refinery product used to pave roads and manufacture roof shingles and various waterproofing products. Diluted bitumen (diluted with naphtha to make it flow in pipelines) is known as dilbit in the Canadian petroleum industry, while bitumen "upgraded" to synthetic crude oil is known as syncrude and syncrude blended with bitumen as synbit. Bitumen is still the preferred geological term for naturally occurring deposits of the solid or semi-solid form of petroleum. Bituminous rock is a form of sandstone impregnated with bitumen. The tar sands of Alberta, Canada are a similar material.


Output: To what type of aggregate did asphalt used to refer?
