Problem: Oklahoma:

The new state became a focal point for the emerging oil industry, as discoveries of oil pools prompted towns to grow rapidly in population and wealth. Tulsa eventually became known as the "Oil Capital of the World" for most of the 20th century and oil investments fueled much of the state's early economy. In 1927, Oklahoman businessman Cyrus Avery, known as the "Father of Route 66", began the campaign to create U.S. Route 66. Using a stretch of highway from Amarillo, Texas to Tulsa, Oklahoma to form the original portion of Highway 66, Avery spearheaded the creation of the U.S. Highway 66 Association to oversee the planning of Route 66, based in his hometown of Tulsa.

Who was the "Father of Route 66"?

A: Cyrus Avery

Problem: Myanmar:

Under British administration, Myanmar was the second-wealthiest country in South-East Asia. It had been the world's largest exporter of rice. Myanmar also had a wealth of natural and labour resources. British Burma began exporting crude oil in 1853, making it one of the earliest petroleum producers in the world. It produced 75% of the world's teak and had a highly literate population. The wealth was however, mainly concentrated in the hands of Europeans. In 1930s, agricultural production fell dramatically as international rice prices declined, and did not recover for several decades.

What wood product was produced primarily in Myanmar during British rule ?
---
A: 75% of the world's teak

Problem: FA Cup:

The FA permitted artificial turf (3G) pitches in all rounds of the competition from the 201415 edition and beyond. Under the 2015-16 rules, the pitch must be of FIFA One Star quality, or Two Star for ties if they involve one of the 92 professional clubs. This followed approval two years previously for their use in the qualifying rounds only - if a team with a 3G pitch progressed to the competition proper, they had to switch their tie to the ground of another eligible entrant with a natural grass pitch. Having been strong proponents of the surface, the first match in the proper rounds to be played on a 3G surface was a televised first round replay at Maidstone United's Gallagher Stadium on 20 November 2015.

Where was the last match with a 3G surface played?

A: unanswerable

Problem: Phonology:

In addition to the minimal units that can serve the purpose of differentiating meaning (the phonemes), phonology studies how sounds alternate, i.e. replace one another in different forms of the same morpheme (allomorphs), as well as, for example, syllable structure, stress, feature geometry, accent, and intonation.

What do phonemes differentiate?
