Input: Indigenous peoples of the Americas
Most Venezuelans have some indigenous heritage, but the indigenous population make up only around 2% of the total population. They speak around 29 different languages and many more dialects, but some of the ethnic groups are very small and their languages are in danger of becoming extinct in the next decades. The most important indigenous groups are the Ye'kuana, the Wayuu, the Pemon and the Warao. The most advanced native people to have lived in present-day Venezuela is thought to have been the Timoto-cuicas, who mainly lived in the Venezuelan Andes. In total it is estimated that there were between 350 thousand and 500 thousand inhabitants, the most densely populated area being the Andean region (Timoto-cuicas), thanks to the advanced agricultural techniques used.

What made the Timoto-cuicas so advanced?
Output: agricultural techniques used

Input: Gene
De novo or "orphan" genes, whose sequence shows no similarity to existing genes, are extremely rare. Estimates of the number of de novo genes in the human genome range from 18 to 60. Such genes are typically shorter and simpler in structure than most eukaryotic genes, with few if any introns. Two primary sources of orphan protein-coding genes are gene duplication followed by extremely rapid sequence change, such that the original relationship is undetectable by sequence comparisons, and formation through mutation of "cryptic" transcription start sites that introduce a new open reading frame in a region of the genome that did not previously code for a protein.

What is one primary source of orphan protein-coding genes?
Output: gene duplication followed by extremely rapid sequence change

Input: Flowering plant
Island genetics provides one proposed explanation for the sudden, fully developed appearance of flowering plants. Island genetics is believed to be a common source of speciation in general, especially when it comes to radical adaptations that seem to have required inferior transitional forms. Flowering plants may have evolved in an isolated setting like an island or island chain, where the plants bearing them were able to develop a highly specialized relationship with some specific animal (a wasp, for example). Such a relationship, with a hypothetical wasp carrying pollen from one plant to another much the way fig wasps do today, could result in the development of a high degree of specialization in both the plant(s) and their partners. Note that the wasp example is not incidental; bees, which, it is postulated, evolved specifically due to mutualistic plant relationships, are descended from wasps.

What is one proposed explanation for the instant appearance of flowering plants?
Output: Island genetics

Input: Zhejiang
Valleys and plains are found along the coastline and rivers. The north of the province lies just south of the Yangtze Delta, and consists of plains around the cities of Hangzhou, Jiaxing, and Huzhou, where the Grand Canal of China enters from the northern border to end at Hangzhou. Another relatively flat area is found along the Qu River around the cities of Quzhou and Jinhua. Major rivers include the Qiangtang and Ou Rivers. Most rivers carve out valleys in the highlands, with plenty of rapids and other features associated with such topography. Well-known lakes include the West Lake of Hangzhou and the South Lake of Jiaxing.

What is a well-known lake of Hangzhou?
Output:
West Lake
