Chicago's first railway opened in 1848. They are called Galena and Chicago Union Railroad as well as the Illinois and Michigan canal. 
 You're welcome. 
 Great. Any other info regarding history or infrastructure? 
 That sounds like a crazy idea! Thanks so much for your help today! 
 Chicago P.D. is my favorite! Had no idea it was in Chicago. Just kidding! Haha. What can you tell me about Chicago's infrastructure?

Sure. Mont Blanc was first climbed way back in 1785. However, most of the Alpine four-thousanders (peaks of at least 4,000m above sea level) weren't climbed until the second half of the 19th century. The Matterhorn ascent in 1865 was considered the end of the golden age of alpinism. 
 That is very interesting! I did not know it was broken into that many sections. Could you provide me with some idea of the ascents? 
 Interesting, seems people have been climbing those mountains for a long time. Do you have any additional information about the Four-thousanders? 
 Unfortunately, I don't have any information about recent years, beyond that the summits of all the peaks in range have been climbed at some point. According to the Union Internationale des Associations d'Alpinisme (UIAA), that's a total of 82 "official" Alpine summits of at least 4,000 feet! 
 Have there been many ascents of the Four-thousanders in recent years?

I do not have any information, but can tell you that it became the first non secular democratic Muslim majority state in history. 
 A very unique history by the sound of it. Speaking of how the country came to be, what can you tell me about its geography? 
 Unfortunately, most of my information is surrounding wars, but a notable fact is the number of ethnic Azerbaijanis in Iran out number those in Azerbaijan. 
 Hey could you tell me about Azerbaijan? 
 What a tragedy. Is there any history of the country that doesn't have to do with war?

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
