Article: According to Strabo, the Greco-Bactrians seem to have had contacts with China through the silk road trade routes (Strabo, XI.XI.I). Indian sources also maintain religious contact between Buddhist monks and the Greeks, and some Greco-Bactrians did convert to Buddhism. Demetrius, son and successor of Euthydemus, invaded north-western India in 180 BC, after the destruction of the Mauryan empire there; the Mauryans were probably allies of the Bactrians (and Seleucids). The exact justification for the invasion remains unclear, but by about 175 BC, the Greeks ruled over parts of north-western India. This period also marks the beginning of the obfuscation of Greco-Bactrian history. Demetrius possibly died about 180 BC; numismatic evidence suggest the existence of several other kings shortly thereafter. It is probable that at this point that the Greco-Bactrian kingdom split into several semi-independent regions for some years, often warring amongst themselves. Heliocles was the last Greek to clearly rule Bactria, his power collapsing in the face of central Asian tribal invasions (Scythian and Yuezhi), by about 130 BCE. However, Greek urban civilisation seems to have continued in Bactria after the fall of the kingdom, having a hellenising effect on the tribes which had displaced Greek-rule. The Kushan empire which followed continued to use Greek on their coinage and Greeks continued being influential in the empire.

Question: When did Demetrius, son of Euthydemus invade north-western India?
Ans: 180 BC


Article: Hunting is the practice of killing or trapping any animal, or pursuing or tracking it with the intent of doing so. Hunting wildlife or feral animals is most commonly done by humans for food, recreation, to remove predators which are dangerous to humans or domestic animals, or for trade. In the 2010s, lawful hunting is distinguished from poaching, which is the illegal killing, trapping or capture of the hunted species. The species that are hunted are referred to as game or prey and are usually mammals and birds.

Question: What animals are usually hunted?
Ans: mammals and birds


Article: The artificial intelligence (AI) of enemies in Twilight Princess is more advanced than that of enemies in The Wind Waker. Enemies react to defeated companions and to arrows or slingshot pellets that pass by, and can detect Link from a greater distance than was possible in previous games.

Question: What does AI stand for?
Ans: artificial intelligence


Article: Incestuous matings by the purple-crowned fairy wren Malurus coronatus result in severe fitness costs due to inbreeding depression (greater than 30% reduction in hatchability of eggs). Females paired with related males may undertake extra pair matings (see Promiscuity#Other animals for 90% frequency in avian species) that can reduce the negative effects of inbreeding. However, there are ecological and demographic constraints on extra pair matings. Nevertheless, 43% of broods produced by incestuously paired females contained extra pair young.

Question: What can reduce the negative effects of inbreeding?
Ans:
Females paired with related males may undertake extra pair matings
