Article: Exposure to antibiotics early in life is associated with increased body mass in humans and mouse models. Early life is a critical period for the establishment of the intestinal microbiota and for metabolic development. Mice exposed to subtherapeutic antibiotic treatment (STAT) with either penicillin, vancomycin, penicillin and vancomycin, or chlortetracycline had altered composition of the gut microbiota as well as its metabolic capabilities. Moreover, research have shown that mice given low-dose penicillin (1 g/g body weight) around birth and throughout the weaning process had an increased body mass and fat mass, accelerated growth, and increased hepatic expression of genes involved in adipogenesis, compared to controlled mice. In addition, penicillin in combination with a high-fat diet increased fasting insulin levels in mice. However, it is unclear whether or not antibiotics cause obesity in humans. Studies have found a correlation between early exposure of antibiotics (<6 months) and increased body mass (at 10 and 20 months). Another study found that the type of antibiotic exposure was also significant with the highest risk of being overweight in those given macrolides compared to penicillin and cephalosporin. Therefore, there is correlation between antibiotic exposure in early life and obesity in humans, but whether or not there is a causal relationship remains unclear. Although there is a correlation between antibiotic use in early life and obesity, the effect of antibiotics on obesity in humans needs to be weighed against the beneficial effects of clinically indicated treatment with antibiotics in infancy.

Question: What is one common result of using antibiotics from a young age?
Ans: increased body mass

Article: Roughly 70% of the area in the RSFSR consisted of broad plains, with mountainous tundra regions mainly concentrated in the east. The area is rich in mineral resources, including petroleum, natural gas, and iron ore.

Question: Along with petroleum and iron ore, what resource was abundant in the RSFSR?

Article: Though the music varied widely between regions and artists, the post-punk movement has been characterized by its "conceptual assault" on rock conventions and rejection of aesthetics perceived of as traditionalist, hegemonic or rockist in favor of experimentation with production techniques and non-rock musical styles such as dub, electronic music, disco, noise, jazz, krautrock, world music and the avant-garde. While post-punk musicians often avoided or intentionally obscured conventional influences, previous musical styles did serve as touchstones for the movement, including particular brands of glam, art rock and "[the] dark undercurrent of '60s music".[nb 1] According to Reynolds, artists once again approached the studio as an instrument, using new recording methods and pursuing novel sonic territories. Author Matthew Bannister wrote that post-punk artists rejected the high cultural references of 1960s rock artists like the Beatles and Bob Dylan as well as paradigms that defined "rock as progressive, as art, as 'sterile' studio perfectionism ... by adopting an avant-garde aesthetic".

Question: What references did post-punk artists specifically reject of the 1960s rock artists?
Ans: high cultural

Article: The Chicago White Stockings, (today's Chicago Cubs), began spring training in Hot Springs, Arkansas in 1886. President Albert Spalding (founder of Spalding Sporting Goods) and player/manager Cap Anson brought their players to Hot Springs and played at the Hot Springs Baseball Grounds. The concept was for the players to have training and fitness before the start of the regular season. After the White Stockings had a successful season in 1886, winning the National League Pennant, other teams began bringing their players to "spring training". The Chicago Cubs, St. Louis Browns, New York Yankees, St. Louis Cardinals, Cleveland Spiders, Detroit Tigers, Pittsburgh Pirates, Cincinnati Reds, New York Highlanders, Brooklyn Dodgers and Boston Red Sox were among the early squads to arrive. Whittington Park (1894) and later Majestic Park (1909) and Fogel Field (1912) were all built in Hot Springs specifically to host Major League teams.

Question: Who began spring training in Hot Springs, Arkansas in 1886?
Ans:
Chicago White Stockings
