Problem: Zhejiang:

At the beginning of the Three Kingdoms era (220–280 CE), Zhejiang was home to the warlords Yan Baihu and Wang Lang prior to their defeat by Sun Ce and Sun Quan, who eventually established the Kingdom of Wu. Despite the removal of their court from Kuaiji to Jianye (present-day Nanjing), they continued development of the region and benefitted from influxes of refugees fleeing the turmoil in northern China. Industrial kilns were established and trade reached as far as Manchuria and Funan (south Vietnam).

What kingdom did Sun Ce and Sun Quan eventually establish?
---
A: the Kingdom of Wu


Problem: Brigham Young University:

Brigham Young University is a part of the Church Educational System of LDS Church. It is organized under a Board of Trustees, with the President of the Church (currently Thomas S. Monson) as chairman. This board consists of the same people as the Church Board of Education, a pattern that has been in place since 1939. Prior to 1939, BYU had a separate board of trustees that was subordinate to the Church Board of Education. The President of BYU, currently Kevin J Worthen, reports to the Board, through the Commissioner of Education.

What is part of the LSD Church?

A: unanswerable


Problem: Zinc:

Zinc(I) compounds are rare, and require bulky ligands to stabilize the low oxidation state. Most zinc(I) compounds contain formally the [Zn2]2+ core, which is analogous to the [Hg2]2+ dimeric cation present in mercury(I) compounds. The diamagnetic nature of the ion confirms its dimeric structure. The first zinc(I) compound containing the Zn—Zn bond, (η5-C5Me5)2Zn2, is also the first dimetallocene. The [Zn2]2+ ion rapidly disproportionates into zinc metal and zinc(II), and has only been obtained as a yellow glass formed by cooling a solution of metallic zinc in molten ZnCl2.

When a solution of metallic zinc is cooled in molten ZnCl2, what is formed?
---
A: yellow glass


Problem: Mali:

Mali faces numerous health challenges related to poverty, malnutrition, and inadequate hygiene and sanitation. Mali's health and development indicators rank among the worst in the world. Life expectancy at birth is estimated to be 53.06 years in 2012. In 2000, 62–65 percent of the population was estimated to have access to safe drinking water and only 69 percent to sanitation services of some kind. In 2001, the general government expenditures on health totalled about US$4 per capita at an average exchange rate.

In 2000 what percentage of the population had access to safe drinking water?
---
A:
62–65
