Problem: To protect crops from wind and drought, the Grain Intendant Zhao Guo () created the alternating fields system (daitianfa ) during Emperor Wu's reign. This system switched the positions of furrows and ridges between growing seasons. Once experiments with this system yielded successful results, the government officially sponsored it and encouraged peasants to use it. Han farmers also used the pit field system (aotian ) for growing crops, which involved heavily fertilized pits that did not require plows or oxen and could be placed on sloping terrain. In southern and small parts of central Han-era China, paddy fields were chiefly used to grow rice, while farmers along the Huai River used transplantation methods of rice production.
What helped insure the safety of crops from wind?
The answer is the following: the alternating fields system

Problem: Palmerston died in 1865, and after a brief ministry led by Russell, Derby returned to power. In 1866, Victoria attended the State Opening of Parliament for the first time since Albert's death. The following year she supported the passing of the Reform Act 1867 which doubled the electorate by extending the franchise to many urban working men, though she was not in favour of votes for women. Derby resigned in 1868, to be replaced by Benjamin Disraeli, who charmed Victoria. "Everyone likes flattery," he said, "and when you come to royalty you should lay it on with a trowel." With the phrase "we authors, Ma'am", he complimented her. Disraeli's ministry only lasted a matter of months, and at the end of the year his Liberal rival, William Ewart Gladstone, was appointed prime minister. Victoria found Gladstone's demeanour far less appealing; he spoke to her, she is thought to have complained, as though she were "a public meeting rather than a woman".
Following Alberts death, what was the first year that Victoria attended the State opening of Parliment?
The answer is the following: 1866

Problem: Himachal Pradesh is governed through a parliamentary system of representative democracy, a feature the state shares with other Indian states. Universal suffrage is granted to residents. The legislature consists of elected members and special office bearers such as the Speaker and the Deputy Speaker who are elected by the members. Assembly meetings are presided over by the Speaker or the Deputy Speaker in the Speaker's absence. The judiciary is composed of the Himachal Pradesh High Court and a system of lower courts. Executive authority is vested in the Council of Ministers headed by the Chief Minister, although the titular head of government is the Governor. The Governor is the head of state appointed by the President of India. The leader of the party or coalition with a majority in the Legislative Assembly is appointed as the Chief Minister by the Governor, and the Council of Ministers are appointed by the Governor on the advice of the Chief Minister. The Council of Ministers reports to the Legislative Assembly. The Assembly is unicameral with 68 Members of the Legislative Assembly (MLA). Terms of office run for 5 years, unless the Assembly is dissolved prior to the completion of the term. Auxiliary authorities known as panchayats, for which local body elections are regularly held, govern local affairs.
