user: From the passage provided, extract the difference in caffeine between a light roast and a dark roast.

assistant: <think>
Sucrose is rapidly lost during the roasting process, and may disappear entirely in darker roasts. During roasting, aromatic oils and acids weaken, changing the flavor; at 205 °C (401 °F), other oils start to develop. One of these oils, caffeol, is created at about 200 °C (392 °F), which is largely responsible for coffee's aroma and flavor. The difference of caffeine content between a light roast and a dark roast is only about 0.1%.</think>
Light roasts and dark roasts differ in caffeine content by about 0.1%.

user: here is a blurb about the 98th Illinois General Assembly, what were the notable laws that were passed?

assistant: <think>
The 98th General Assembly enacted a total of 1,175 bills into law. Notable among these was the Illinois Religious Freedom and Marriage Fairness Act, which removed legal barriers to same-sex marriage in Illinois. The House of Representatives passed the bill by a 61–54 vote on November 5, 2013, and the Senate passed it by a 32–21 vote. The governor signed the bill into law on November 20, and the law took effect on June 1, 2014.

The General Assembly also passed the Illinois Bill of Rights for the Homeless, which made Illinois the second state to ban discrimination against the homeless.

The General Assembly also passed the Firearm Concealed Carry Act (FCCA), a change to Illinois gun law that made Illinois the last state in the country to enact concealed carry. Passed over the governor's veto, the FCCA took effect "mere hours before the seventh circuit's deadline" in Moore v. Madigan.

Late in the legislative session, the General Assembly passed a bill that changes the original Illinois wiretapping law adding that in order to commit a criminal offense, a person must be recording "in a surreptitious manner". On December 30, 2014, Governor Quinn signed the bill into law as Public Act 098-1142. The bill's sponsors, Elaine Nekritz and Kwame Raoul, claimed the law upholds the rights of citizens to record in public.

The General Assembly approved five ballot measures for the 2014 Illinois general election, an unusually large number for the state, including three advisory referendums and two constitutional amendments. The constitutional amendments, Marsy's Law and the Illinois Right to Vote Amendment, both passed with the required 60% majority of the popular vote.</think>

user: Based on this article, how did the existence of trains impact the development of Roche Percee?

assistant: <think>
In 1872 the Boundary Commission travelled through this area while surveying the border between Canada and the United States. During the 1874 March West trek of the North-West Mounted Police, the force established its first camp (called Short Creek Camp) at this location. The community began being served by the Soo Line in 1893, permitting the coal mines in the region to become operational. Roche Percée incorporated as a village on January 12, 1909.</think>
The area that became Roche Percee was impacted by trains when the Soo Line connected the village to a train line. This train line allowed for coal mining in the region to develop by providing access for transporting coal. After the development of these coal mines, the area was eventually able to grow enough to become incorporated as a village.
