Problem: Tuvalu:

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.

How much increase in land space did the filling of the borrow pits cause?
---
A: eight per cent

Problem: Rajasthan:

Modern Rajasthan includes most of Rajputana, which comprises the erstwhile nineteen princely states, two chiefships, and the British district of Ajmer-Merwara. Marwar (Jodhpur), Bikaner, Mewar (Chittorgarh), Alwar and Dhundhar (Jaipur) were some of the main Rajput princely states. Bharatpur and Dholpur were Jat princely states whereas Tonk was a princely state under a Muslim Nawab. Rajput families rose to prominence in the 6th century CE. The Rajputs put up a valiant resistance to the Islamic invasions and protected this land with their warfare and chivalry for more than 500 years. They also resisted Mughal incursions into India and thus contributed to their slower-than-anticipated access to the Indian subcontinent. Later, the Mughals, through skilled warfare, were able to get a firm grip on northern India, including Rajasthan. Mewar led other kingdoms in its resistance to outside rule. Most notably, Rana Sanga fought the Battle of Khanua against Babur, the founder of the Mughal empire.

During what era did Marwar familes become prominent?
---
A: unanswerable

Problem: Bird:

Breeding usually involves some form of courtship display, typically performed by the male. Most displays are rather simple and involve some type of song. Some displays, however, are quite elaborate. Depending on the species, these may include wing or tail drumming, dancing, aerial flights, or communal lekking. Females are generally the ones that drive partner selection, although in the polyandrous phalaropes, this is reversed: plainer males choose brightly coloured females. Courtship feeding, billing and allopreening are commonly performed between partners, generally after the birds have paired and mated.

Which gender typically performs some form of courtship display?
---
A: male

Problem: Child labour:

In southeast Asian colonies, such as Hong Kong, child labour such as the Mui Tsai (), was rationalised as a cultural tradition and ignored by British authorities. The Dutch East India Company officials rationalised their child labour abuses with, "it is a way to save these children from a worse fate." Christian mission schools in regions stretching from Zambia to Nigeria too required work from children, and in exchange provided religious education, not secular education. Elsewhere, the Canadian Dominion Statutes in form of so-called Breaches of Contract Act, stipulated jail terms for uncooperative child workers.

Did the child workers receive anything from the christian mission schools?
---
A:
provided religious education
