Question: Approximately 10,000 years ago, desertification forced hunter-gatherer societies south into the Sahel regions of northern Central Africa, where some groups settled and began farming as part of the Neolithic Revolution. Initial farming of white yam progressed into millet and sorghum, and before 3000 BC the domestication of African oil palm improved the groups' nutrition and allowed for expansion of the local populations. Bananas arrived in the region and added an important source of carbohydrates to the diet; they were also used in the production of alcoholic beverages.[when?] This Agricultural Revolution, combined with a "Fish-stew Revolution", in which fishing began to take place, and the use of boats, allowed for the transportation of goods. Products were often moved in ceramic pots, which are the first known examples of artistic expression from the region's inhabitants.
Is there an answer to this question: What did dedertification allow for the expansion of?

Answer: unanswerable

Question: In 1992, Yitzhak Rabin became Prime Minister following an election in which his party called for compromise with Israel's neighbors. The following year, Shimon Peres on behalf of Israel, and Mahmoud Abbas for the PLO, signed the Oslo Accords, which gave the Palestinian National Authority the right to govern parts of the West Bank and the Gaza Strip. The PLO also recognized Israel's right to exist and pledged an end to terrorism. In 1994, the IsraelJordan Treaty of Peace was signed, making Jordan the second Arab country to normalize relations with Israel. Arab public support for the Accords was damaged by the continuation of Israeli settlements and checkpoints, and the deterioration of economic conditions. Israeli public support for the Accords waned as Israel was struck by Palestinian suicide attacks. Finally, while leaving a peace rally in November 1995, Yitzhak Rabin was assassinated by a far-right-wing Jew who opposed the Accords.
Is there an answer to this question: Who became the Prime Minister in 1992?

Answer: Yitzhak Rabin

Question: Eleven days after Orsini's assassination attempt in France, Victoria's eldest daughter married Prince Frederick William of Prussia in London. They had been betrothed since September 1855, when Princess Victoria was 14 years old; the marriage was delayed by the Queen and Prince Albert until the bride was 17. The Queen and Albert hoped that their daughter and son-in-law would be a liberalising influence in the enlarging Prussian state. Victoria felt "sick at heart" to see her daughter leave England for Germany; "It really makes me shudder", she wrote to Princess Victoria in one of her frequent letters, "when I look round to all your sweet, happy, unconscious sisters, and think I must give them up too one by one." Almost exactly a year later, Princess Victoria gave birth to the Queen's first grandchild, Wilhelm, who would become the last German Kaiser.
Is there an answer to this question: Who did Princess Victoria marry at the age of 17?

Answer:
Prince Frederick William of Prussia
