Problem: Crucifixion of Jesus:

Luke's gospel also describes an interaction between Jesus and the women among the crowd of mourners following him, quoting Jesus as saying "Daughters of Jerusalem, do not weep for me, but weep for yourselves and for your children. For behold, the days are coming when they will say, 'Blessed are the barren and the wombs that never bore and the breasts that never nursed!' Then they will begin to say to the mountains, 'Fall on us,' and to the hills, 'Cover us.' For if they do these things when the wood is green, what will happen when it is dry?"[Lk. 23:28-31]

What color did some women in Jerusalem like to wear?

A: unanswerable


Problem: Incandescent light bulb:

While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.

How does the molecular weight of a gas relate to thermal conductivity?
---
A: Higher molecular weight gasses have lower thermal conductivity


Problem: Hindu philosophy:

Early history of Shaivism is difficult to determine. However, the Śvetāśvatara Upanishad (400 – 200 BCE) is considered to be the earliest textual exposition of a systematic philosophy of Shaivism. Shaivism is represented by various philosophical schools, including non-dualist (abheda), dualist (bheda), and non-dualist-with-dualist (bhedābheda) perspectives. Vidyaranya in his works mentions three major schools of Shaiva thought— Pashupata Shaivism, Shaiva Siddhanta and Pratyabhijña (Kashmir Shaivism).

When was the text on Shaivism written?
---
A: 400 – 200 BCE


Problem: Nanjing:

As in most of eastern China the ethnic makeup of Nanjing is predominantly Han nationality (98.56 percent), with 50 other minority nationalities. In 1999, 77,394 residents belonged to minority nationalities, among which the vast majority (64,832) were Hui nationalities, contributing 83.76 percent to the minority population. The second and third largest minority groups were Manchu (2,311) and Zhuang (533) nationalities. Most of the minority nationalities resided in Jianye District, comprising 9.13 percent of the district's population.
