Input: Read this: Judaism shares some of the characteristics of a nation, an ethnicity, a religion, and a culture, making the definition of who is a Jew vary slightly depending on whether a religious or national approach to identity is used. Generally, in modern secular usage Jews include three groups: people who were born to a Jewish family regardless of whether or not they follow the religion, those who have some Jewish ancestral background or lineage (sometimes including those who do not have strictly matrilineal descent), and people without any Jewish ancestral background or lineage who have formally converted to Judaism and therefore are followers of the religion.

Input: Read this: The eastern shoreline of Funafuti Lagoon was modified during World War II when the airfield (what is now Funafuti International Airport) was constructed. The coral base of the atoll was used as fill to create the runway. The resulting borrow pits impacted the fresh-water aquifer. In the low areas of Funafuti the sea water can be seen bubbling up through the porous coral rock to form pools with each high tide. Since 1994 a project has been in development to assess the environmental impact of transporting sand from the lagoon to fill all the borrow pits and low-lying areas on Fongafale. In 2014 the Tuvalu Borrow Pits Remediation (BPR) project was approved in order to fill 10 borrow pits, leaving Tafua Pond, which is a natural pond. The New Zealand Government funded the BPR project. The project was carried out in 2015 with 365,000 sqm of sand being dredged from the lagoon to fill the holes and improve living conditions on the island. This project increase the usable land space on Fongafale by eight per cent.
Question: What has the pits from the Tuvalu air runways construction impacted?

Output: fresh-water aquifer

Input: Read this: A year before Alfonso III "the Great" of Asturias death, three of Alfonso's sons rose in rebellion and forced him to abdicate, partitioning the kingdom among them. The eldest son, Garcia, became king of Leon. The second son, Ordono, reigned in Galicia, while the third, Fruela, received Asturias with Oviedo as his capital. Alfonso died in Zamora, probably in 910. His former realm would be reunited when first Garcia died childless and Leon passed to Ordono. He in turn died when his children were too young to ascend; Fruela became king of a reunited crown. His death the next year initiated a series of internecine struggles that led to unstable succession for over a century. It continued under that name[clarification needed] until incorporated into the Kingdom of Castile in 1230, after Ferdinand III became joint king of the two kingdoms. This was done to avoid dynastic feuds and to maintain the Christian Kingdoms strong enough to prevent complete Muslim take over of the Iberian Peninsula and to further the Reconquista of Iberia by Christian armies.
Question: In which year was the Kingdom of Castile formed?

Output:
1230
