Problem: Southeast Asia:

Homo sapiens reached the region by around 45,000 years ago, having moved eastwards from the Indian subcontinent. Homo floresiensis also lived in the area up until 12,000 years ago, when they became extinct. Austronesian people, who form the majority of the modern population in Indonesia, Malaysia, Brunei, East Timor, and the Philippines, may have migrated to Southeast Asia from Taiwan. They arrived in Indonesia around 2000 BC,and as they spread through the archipelago, they often settled along coastal areas and confined indigenous peoples such as Negritos of the Philippines or Papuans of New Guinea to inland regions.

A: unanswerable

Problem: Hydrogen:

A molecular form called protonated molecular hydrogen (H+
3) is found in the interstellar medium, where it is generated by ionization of molecular hydrogen from cosmic rays. This charged ion has also been observed in the upper atmosphere of the planet Jupiter. The ion is relatively stable in the environment of outer space due to the low temperature and density. H+
3 is one of the most abundant ions in the Universe, and it plays a notable role in the chemistry of the interstellar medium. Neutral triatomic hydrogen H3 can only exist in an excited form and is unstable. By contrast, the positive hydrogen molecular ion (H+
2) is a rare molecule in the universe.

What molecular form is found in the interstellar medium?
---
A: protonated molecular hydrogen

Problem: Hellenistic period:

After Cassander's death in 298 BCE, however, Demetrius, who still maintained a sizable loyal army and fleet, invaded Macedon, seized the Macedonian throne (294) and conquered Thessaly and most of central Greece (293-291). He was defeated in 288 BC when Lysimachus of Thrace and Pyrrhus of Epirus invaded Macedon on two fronts, and quickly carved up the kingdom for themselves. Demetrius fled to central Greece with his mercenaries and began to build support there and in the northern Peloponnese. He once again laid siege to Athens after they turned on him, but then struck a treaty with the Athenians and Ptolemy, which allowed him to cross over to Asia minor and wage war on Lysimachus' holdings in Ionia, leaving his son Antigonus Gonatas in Greece. After initial successes, he was forced to surrender to Seleucus in 285 and later died in captivity. Lysimachus, who had seized Macedon and Thessaly for himself, was forced into war when Seleucus invaded his territories in Asia minor and was defeated and killed in 281 BCE at the Battle of Corupedium, near Sardis. Seleucus then attempted to conquer Lysimachus' European territories in Thrace and Macedon, but he was assassinated by Ptolemy Ceraunus ("the thunderbolt"), who had taken refuge at the Seleucid court and then had himself acclaimed as king of Macedon. Ptolemy was killed when Macedon was invaded by Gauls in 279, his head stuck on a spear and the country fell into anarchy. Antigonus II Gonatas invaded Thrace in the summer of 277 and defeated a large force of 18,000 Gauls. He was quickly hailed as king of Macedon and went on to rule for 35 years.

When did Demetrius seize the Macedonian throne?
---
A: 294

Problem: Egypt:

Muhammad Ali Pasha evolved the military from one that convened under the tradition of the corvee to a great modernised army. He introduced conscription of the male peasantry in 19th century Egypt, and took a novel approach to create his great army, strengthening it with numbers and in skill. Education and training of the new soldiers was not an option; the new concepts were furthermore enforced by isolation. The men were held in barracks to avoid distraction of their growth as a military unit to be reckoned with. The resentment for the military way of life eventually faded from the men and a new ideology took hold, one of nationalism and pride. It was with the help of this newly reborn martial unit that Muhammad Ali imposed his rule over Egypt.

Who modernized Egyptian army?
---
A:
Muhammad Ali Pasha
