Problem: Please answer a question about the following article about Seattle:
The main mode of transportation, however, relies on Seattle's streets, which are laid out in a cardinal directions grid pattern, except in the central business district where early city leaders Arthur Denny and Carson Boren insisted on orienting their plats relative to the shoreline rather than to true North. Only two roads, Interstate 5 and State Route 99 (both limited-access highways), run uninterrupted through the city from north to south. State Route 99 runs through downtown Seattle on the Alaskan Way Viaduct, which was built in 1953. However, due to damage sustained during the 2001 Nisqually earthquake the viaduct will be replaced by a tunnel. The 2-mile (3.2 km) Alaskan Way Viaduct replacement tunnel was originally scheduled to be completed in December 2015 at a cost of US$4.25 billion. Unfortunately, due to issues with the worlds largest tunnel boring machine (TBM), which is nicknamed "Bertha" and is 57 feet (17 m) in diameter, the projected date of completion has been pushed back to 2017. Seattle has the 8th worst traffic congestion of all American cities, and is 10th among all North American cities.
What is planned to replace the Alaska Way Viaduct?
A: tunnel

Problem: Please answer a question about the following article about Avicenna:
Avicenna's astronomical writings had some influence on later writers, although in general his work could be considered less developed than Alhazen or Al-Biruni. One important feature of his writing is that he considers mathematical astronomy as a separate discipline to astrology. He criticized Aristotle's view of the stars receiving their light from the Sun, stating that the stars are self-luminous, and believed that the planets are also self-luminous. He claimed to have observed Venus as a spot on the Sun. This is possible, as there was a transit on May 24, 1032, but Avicenna did not give the date of his observation, and modern scholars have questioned whether he could have observed the transit from his location at that time; he may have mistaken a sunspot for Venus. He used his transit observation to help establish that Venus was, at least sometimes, below the Sun in Ptolemaic cosmology, i.e. the sphere of Venus comes before the sphere of the Sun when moving out from the Earth in the prevailing geocentric model.
What subject did Avicenna consider to be a separate discipline from astrology?
A: mathematical astronomy
Problem: Please answer a question about the following article about North Carolina:
On November 21, 1789, North Carolina became the twelfth state to ratify the Constitution. In 1840, it completed the state capitol building in Raleigh, still standing today. Most of North Carolina's slave owners and large plantations were located in the eastern portion of the state. Although North Carolina's plantation system was smaller and less cohesive than that of Virginia, Georgia, or South Carolina, significant numbers of planters were concentrated in the counties around the port cities of Wilmington and Edenton, as well as suburban planters around the cities of Raleigh, Charlotte, and Durham in the Piedmont. Planters owning large estates wielded significant political and socio-economic power in antebellum North Carolina, which was a slave society. They placed their interests above those of the generally non-slave-holding "yeoman" farmers of western North Carolina. In mid-century, the state's rural and commercial areas were connected by the construction of a 129-mile (208 km) wooden plank road, known as a "farmer's railroad", from Fayetteville in the east to Bethania (northwest of Winston-Salem).
What part of the state were most slave and plantation owners concentrated in?
A:
eastern
