Input: Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

Input: Hamilton argued that the natural faculties of blacks were as good as those of free whites, and he warned that the British would arm the slaves if the patriots did not. In his 21st-century biography, Chernow cites this incident as evidence that Hamilton and Laurens saw the Revolution and the struggle against slavery as inseparable. Hamilton attacked his political opponents as demanding freedom for themselves and refusing to allow it to blacks. In January 1785, Hamilton attended the second meeting of the New York Manumission Society (NYMS). John Jay was president and Hamilton was the first secretary and later became president. Chernow notes how the membership soon included many of Hamilton's friends and associates. Hamilton was a member of the committee of the society that petitioned the legislature to end the slave trade, and that succeeded in passing legislation banning the export of slaves from New York. In the same period, Hamilton felt bound by the rule of law of the time and his law practice facilitated the return of a fugitive slave to Henry Laurens of South Carolina. He opposed the compromise at the 1787 Constitutional Convention by which the federal government could not abolish the slave trade for 20 years, and was disappointed when he lost that argument. Hamilton never supported forced emigration for freed slaves. Horton has argued from this that he would be comfortable with a multiracial society, and that this distinguished him from his contemporaries. In international affairs, he supported Toussaint L'Ouverture's black government in Haiti after the revolt that overthrew French control, as he had supported aid to the slaveowners in 1791--both measures hurt France. Scant evidence has been interpreted by a few to indicate Hamilton may have owned household slaves, as did many wealthy New Yorkers (the evidence for this is indirect; McDonald interprets it as referring to paid employees).
"When did Hamilton attend the second meeting of the NYMS where he later became president of?" is "1787"?

Input: Alexander II's death caused a great setback for the reform movement. One of his last ideas was to draft plans for an elected parliament, or Duma, which were completed the day before he died but not yet released to the Russian people. In a matter of 48 hours, Alexander II planned to release his plan for the duma to the Russian people. Had he lived, Russia might have followed a path to constitutional monarchy instead of the long road of oppression that defined his successor's reign. The first action Alexander III took after his father's death was to tear up those plans. A Duma would not come into fruition until 1905, when Alexander II's grandson, Nicholas II, commissioned the Duma following extreme pressure on the monarchy as a result of the Russian Revolution of 1905. The assassination triggered major suppression of civil liberties in Russia, and police brutality burst back in full force after experiencing some restraint under the reign of Alexander II, whose death was witnessed first-hand by his son, Alexander III, and his grandson, Nicholas II, both future emperors who vowed not to have the same fate befall them. Both of them used the Okhrana to arrest protestors and uproot suspected rebel groups, creating further suppression of personal freedom for the Russian people. A series of anti-Jewish pogroms and antisemitic legislation, the May Laws, were yet another result. Finally, the tsar's assassination also inspired anarchists to advocate "'propaganda by deed'--the use of a spectacular act of violence to incite revolution." With construction starting in 1883, the Church of the Savior on Blood was built on the site of Alexander's assassination and dedicated in his memory.
"How many years passed between the fruition of the Duma and the beginning of the construction of the Church of the Savior on Blood?" is "5 years"?
