Problem: As a result of continued warming, the polar ice caps melted and much of Gondwana became a desert. In Eastern Antarctica, seed ferns or pteridosperms became abundant and large amounts of sandstone and shale were laid down at this time. Synapsids, commonly known as "mammal-like reptiles", were common in Antarctica during the Early Triassic and included forms such as Lystrosaurus. The Antarctic Peninsula began to form during the Jurassic period (206–146 Ma), and islands gradually rose out of the ocean. Ginkgo trees, conifers, bennettites, horsetails, ferns and cycads were plentiful during this period. In West Antarctica, coniferous forests dominated through the entire Cretaceous period (146–66 Ma), though southern beech became more prominent towards the end of this period. Ammonites were common in the seas around Antarctica, and dinosaurs were also present, though only three Antarctic dinosaur genera (Cryolophosaurus and Glacialisaurus, from the Hanson Formation, and Antarctopelta) have been described to date. It was during this era that Gondwana began to break up.
During what period did Gondwana begin to break apart?
---
Answer: Cretaceous


Problem: To make pulp from wood, a chemical pulping process separates lignin from cellulose fibres. This is accomplished by dissolving lignin in a cooking liquor, so that it may be washed from the cellulose; this preserves the length of the cellulose fibres. Paper made from chemical pulps are also known as wood-free papers–not to be confused with tree-free paper; this is because they do not contain lignin, which deteriorates over time. The pulp can also be bleached to produce white paper, but this consumes 5% of the fibres; chemical pulping processes are not used to make paper made from cotton, which is already 90% cellulose.
 What percentage of fibres are used in the bleaching process?
---
Answer: unanswerable


Problem: 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).
What was the name of Shen Fu's memoir?
---
Answer:
Six Chapters of a Floating Life
