On the text of María Teresa Ruiz : "Children of the stars". 1) How can we "see" the past and reconstruct the "history of the universe"?​

well stockyards mean a large yard containing pens and sheds, typically adjacent to a slaughterhouse, in which livestock is kept and sorted. and i'm assuming that by party you   mean a large group of people which does make sense because chicago is a very crowded place much like new york. stockyards tend to take up a lot of room due to needing the area for pens to keep animals in and the fact that stockyards are usually right by slaughterhouse where they process and distribute the product. so its much like a zoo but with some dead animal products close by.

3 is blunder, i’m not sure about the last one but the first two look correct
