By 6000 BCE predynastic Egyptians in the southwestern corner of Egypt were herding cattle and constructing large buildings. Subsistence in organized and permanent settlements in predynastic Egypt by the middle of the 6th millennium BCE centered predominantly on cereal and animal agriculture: cattle, goats, pigs and sheep. Metal objects replaced prior ones of stone. Tanning of animal skins, pottery and weaving were commonplace in this era also. There are indications of seasonal or only temporary occupation of the Al Fayyum in the 6th millennium BCE, with food activities centering on fishing, hunting and food-gathering. Stone arrowheads, knives and scrapers from the era are commonly found. Burial items included pottery, jewelry, farming and hunting equipment, and assorted foods including dried meat and fruit. Burial in desert environments appears to enhance Egyptian preservation rites, and dead were buried facing due west.

What were Egyptians herding in the early BCE period?
Output: cattle

Input: List of numbered streets in Manhattan
155th Street starts on the West Side at Riverside Drive, crossing Broadway, Amsterdam Avenue and St. Nicholas Avenue. At St. Nicholas Place, the terrain drops off steeply, and 155th Street is carried on a 1,600-foot (490 m) long viaduct, a City Landmark constructed in 1893, that slopes down towards the Harlem River, continuing onto the Macombs Dam Bridge, crossing over (but not intersecting with) the Harlem River Drive. A separate, unconnected section of 155th Street runs under the viaduct, connecting Bradhurst Avenue and the Harlem River Drive.

In what year was the viaduct along 155th Street constructed?
Output: 1893

Input: European Central Bank
This changed with the recent sovereign-debt crisis. The ECB always could, and through the late summer of 2011 did, purchase bonds issued by the weaker states even though it assumes, in doing so, the risk of a deteriorating balance sheet. ECB buying focused primarily on Spanish and Italian debt. Certain techniques can minimise the impact. Purchases of Italian bonds by the central bank, for example, were intended to dampen international speculation and strengthen portfolios in the private sector and also the central bank.

Why were italian bonds purchased by the ECB?
Output: intended to dampen international speculation and strengthen portfolios in the private sector and also the central bank

The Prime Minister has the right to appoint a maximum of three such ministers, as the limit of ministers in one government is fifteen. It is also known as the cabinet. The cabinet carries out the country's domestic and foreign policy, shaped by parliament; it directs and co-ordinates the work of government institutions and bears full responsibility for everything occurring within the authority of executive power. The government, headed by the Prime Minister, thus represents the political leadership of the country and makes decisions in the name of the whole executive power.

What strategy does the cabinet execute?
Output:
domestic and foreign policy
