Problem: Adolescence:

Over the course of adolescence, the amount of white matter in the brain increases linearly, while the amount of grey matter in the brain follows an inverted-U pattern. Through a process called synaptic pruning, unnecessary neuronal connections in the brain are eliminated and the amount of grey matter is pared down. However, this does not mean that the brain loses functionality; rather, it becomes more efficient due to increased myelination (insulation of axons) and the reduction of unused pathways.

During which process are unnecessary neuronal connections in the brain eliminated?
---
A: synaptic pruning

Problem: Crucifixion of Jesus:

The assumption of the use of a two-beamed cross does not determine the number of nails used in the crucifixion and some theories suggest three nails while others suggest four nails. However, throughout history larger numbers of nails have been hypothesized, at times as high as 14 nails. These variations are also present in the artistic depictions of the crucifixion. In the Western Church, before the Renaissance usually four nails would be depicted, with the feet side by side. After the Renaissance most depictions use three nails, with one foot placed on the other. Nails are almost always depicted in art, although Romans sometimes just tied the victims to the cross. The tradition also carries to Christian emblems, e.g. the Jesuits use three nails under the IHS monogram and a cross to symbolize the crucifixion.

How many nails were suggested they used for the crucifixion?
---
A: three nails

Problem: Xbox 360:

When the Xbox 360 was released, Microsoft's online gaming service Xbox Live was shut down for 24 hours and underwent a major upgrade, adding a basic non-subscription service called Xbox Live Silver (later renamed Xbox Live Free) to its already established premium subscription-based service (which was renamed Gold). Xbox Live Free is included with all SKUs of the console. It allows users to create a user profile, join on message boards, and access Microsoft's Xbox Live Arcade and Marketplace and talk to other members. A Live Free account does not generally support multiplayer gaming; however, some games that have rather limited online functions already, (such as Viva Pinata) or games that feature their own subscription service (e.g. EA Sports games) can be played with a Free account. Xbox Live also supports voice the latter a feature possible with the Xbox Live Vision.

What is an example of a game that does not support multiplayer online?
---
A: unanswerable

Problem: Qing dynasty:

Literature grew to new heights in the Qing period. Poetry continued as a mark of the cultivated gentleman, but women wrote in larger and larger numbers and poets came from all walks of life. The poetry of the Qing dynasty is a lively field of research, being studied (along with the poetry of the Ming dynasty) for its association with Chinese opera, developmental trends of Classical Chinese poetry, the transition to a greater role for vernacular language, and for poetry by women in Chinese culture. The Qing dynasty was a period of much literary collection and criticism, and many of the modern popular versions of Classical Chinese poems were transmitted through Qing dynasty anthologies, such as the Quantangshi and the Three Hundred Tang Poems. Pu Songling brought the short story form to a new level in his Strange Stories from a Chinese Studio, published in the mid-18th century, and Shen Fu demonstrated the charm of the informal memoir in Six Chapters of a Floating Life, written in the early 19th century but published only in 1877. The art of the novel reached a pinnacle in Cao Xueqin's Dream of the Red Chamber, but its combination of social commentary and psychological insight were echoed in highly skilled novels such as Wu Jingzi's The Scholars (1750) and Li Ruzhen's Flowers in the Mirror (1827).

Who wrote the novel Dream of the Red Chamber?

A:
Cao Xueqin
