Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
By the mid-18th century, Charles Town had become a bustling trade center, the hub of the Atlantic trade for the southern colonies. Charles Towne was also the wealthiest and largest city south of Philadelphia, in part because of the lucrative slave trade. By 1770, it was the fourth-largest port in the colonies, after Boston, New York, and Philadelphia, with a population of 11,000slightly more than half of them slaves. By 1708, the majority of the colony's population was slaves, and the future state would continue to be a majority of African descent until after the Great Migration of the early 20th century.

Context and question: Digimon was first conceived as a virtual pet toy in the vein of Tamagotchis and, as such, took influence from Tamagotchis' cute and round designs. The small areas of the screens (16 by 16 pixels) meant that character designers had to create monsters whose forms would be easily recognizable. As such, many of the early Digimonincluding Tyrannomon, the first one ever createdwere based on dinosaurs. Many further designs were created by Kenji Watanabe, who was brought in to help with the "X-Antibody" creatures and art for the Digimon collectible card game. Watanabe was one influenced by American comics, which were beginning to gain popularity in Japan, and as such began to make his characters look stronger and "cool." The character creation process, however, has for most of the franchise's history been collaborative and reliant on conversation and brainstorming.
What were becoming unpopular in Japan?

Question: The Convention came into force as international law on 12 January 1951 after the minimum 20 countries became parties. At that time however, only two of the five permanent members of the UN Security Council were parties to the treaty: France and the Republic of China. The Soviet Union ratified in 1954, the United Kingdom in 1970, the People's Republic of China in 1983 (having replaced the Taiwan-based Republic of China on the UNSC in 1971), and the United States in 1988. This long delay in support for the Convention by the world's most powerful nations caused the Convention to languish for over four decades. Only in the 1990s did the international law on the crime of genocide begin to be enforced.
Is there an answer to this question: Of the five permanent members of the UN Security Council, how many were parties to the treaty?

Answer: only two

QUES: Japanese land forces continued to advance in the Solomon Islands and New Guinea. From July 1942, a few Australian reserve battalions, many of them very young and untrained, fought a stubborn rearguard action in New Guinea, against a Japanese advance along the Kokoda Track, towards Port Moresby, over the rugged Owen Stanley Ranges. The militia, worn out and severely depleted by casualties, were relieved in late August by regular troops from the Second Australian Imperial Force, returning from action in the Mediterranean theater. In early September 1942 Japanese marines attacked a strategic Royal Australian Air Force base at Milne Bay, near the eastern tip of New Guinea. They were beaten back by Allied (primarily Australian Army) forces.

What forces releived the worn Australian reserve battalions?
What is the answer?
ANS:
Second Australian Imperial Force
