Input: Asphalt
Roads in the US have been paved with materials that include asphalt/bitumen since at least 1870, when a street in front of the Newark, NJ City Hall was paved. In many cases, these early pavings were made from naturally occurring "bituminous rock", such as at Ritchie Mines in Macfarlan in Ritchie County, West Virginia from 1852 to 1873. In 1876, asphalt-based paving was used to pave Pennsylvania Avenue in Washington, DC, in time for the celebration of the national centennial. Asphalt/bitumen was also used for flooring, paving and waterproofing of baths and swimming pools during the early 20th century, following similar trends in Europe.

From what Virginia  mines was asphalt obtained for early street pavings?
Output: Ritchie Mines

Input: Queen Victoria
Eleven days after Orsini's assassination attempt in France, Victoria's eldest daughter married Prince Frederick William of Prussia in London. They had been betrothed since September 1855, when Princess Victoria was 14 years old; the marriage was delayed by the Queen and Prince Albert until the bride was 17. The Queen and Albert hoped that their daughter and son-in-law would be a liberalising influence in the enlarging Prussian state. Victoria felt "sick at heart" to see her daughter leave England for Germany; "It really makes me shudder", she wrote to Princess Victoria in one of her frequent letters, "when I look round to all your sweet, happy, unconscious sisters, and think I must give them up too – one by one." Almost exactly a year later, Princess Victoria gave birth to the Queen's first grandchild, Wilhelm, who would become the last German Kaiser.

When was Victoria's oldest daughter married?
Output: Eleven days after Orsini's assassination attempt

Input: Bird
Most birds scoop water in their beaks and raise their head to let water run down the throat. Some species, especially of arid zones, belonging to the pigeon, finch, mousebird, button-quail and bustard families are capable of sucking up water without the need to tilt back their heads. Some desert birds depend on water sources and sandgrouse are particularly well known for their daily congregations at waterholes. Nesting sandgrouse and many plovers carry water to their young by wetting their belly feathers. Some birds carry water for chicks at the nest in their crop or regurgitate it along with food. The pigeon family, flamingos and penguins have adaptations to produce a nutritive fluid called crop milk that they provide to their chicks.

What is crop milk?
Output: a nutritive fluid

Input: Mary (mother of Jesus)
The adoption of the mother of Jesus as a virtual goddess may represent a reintroduction of aspects of the worship of Isis. "When looking at images of the Egyptian goddess Isis and those of the Virgin Mary, one may initially observe iconographic similarities. These parallels have led many scholars to suggest that there is a distinct iconographic relationship between Isis and Mary. In fact, some scholars have gone even further, and have suggested, on the basis of this relationship, a direct link between the cult of Mary and that of Isis." 

Which Egyptian goddess do some scholars ascribe similarities to?
Output:
Isis
