Problem: In an ecosystem, predation is a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked). Predators may or may not kill their prey prior to feeding on them, but the act of predation often results in the death of the prey and the eventual absorption of the prey's tissue through consumption. Thus predation is often, though not always, carnivory. Other categories of consumption are herbivory (eating parts of plants), fungivory (eating parts of fungi), and detritivory (the consumption of dead organic material (detritus)). All these consumption categories fall under the rubric of consumer-resource systems. It can often be difficult to separate various types of feeding behaviors. For example, some parasitic species prey on a host organism and then lay their eggs on it for their offspring to feed on it while it continues to live in or on its decaying corpse after it has died. The key characteristic of predation however is the predator's direct impact on the prey population. On the other hand, detritivores simply eat dead organic material arising from the decay of dead individuals and have no direct impact on the "donor" organism(s).

Problem: Zeng Guofan had no prior military experience. Being a classically educated official, he took his blueprint for the Xiang Army from the Ming general Qi Jiguang, who, because of the weakness of regular Ming troops, had decided to form his own "private" army to repel raiding Japanese pirates in the mid-16th century. Qi Jiguang's doctrine was based on Neo-Confucian ideas of binding troops' loyalty to their immediate superiors and also to the regions in which they were raised. Zeng Guofan's original intention for the Xiang Army was simply to eradicate the Taiping rebels. However, the success of the Yongying system led to its becoming a permanent regional force within the Qing military, which in the long run created problems for the beleaguered central government.
Who inspired Zeng Guofan in creating his army?

Answer: Qi Jiguang


Problem: The Qur'an relates detailed narrative accounts of Maryam (Mary) in two places, Qur'an 3:35–47 and 19:16–34. These state beliefs in both the Immaculate Conception of Mary and the Virgin birth of Jesus. The account given in Sura 19 is nearly identical with that in the Gospel according to Luke, and both of these (Luke, Sura 19) begin with an account of the visitation of an angel upon Zakariya (Zecharias) and Good News of the birth of Yahya (John), followed by the account of the annunciation. It mentions how Mary was informed by an angel that she would become the mother of Jesus through the actions of God alone.
Which Sura in the Qur'an describes the visitation of an angel upon Zakariya?
