A Spark Neglected Burns the House
by Leo Tolstoy (adapted excerpt)
There once lived in a village a peasant named Iván Stcherbakóf. He was comfortably off, in the prime of life, the best worker in the village, and
had three sons all able to work. The eldest was married, the second about to marry, and the third was a big lad who could mind the horses and
was already beginning to plough. Iván's wife was an able and thrifty woman, and they were fortunate in having a quiet, hard-working daughter-
in-law. There was nothing to prevent Iván and his family from living happily. They had only one idle mouth to feed; that was Iván's old father,
who suffered from asthma and had been lying ill for seven years. Iván had all he needed three horses and a colt, a cow with a calf, and fifteen
sheep. The women made all the clothing for the family, besides helping in the fields, and the men tilled the land. They always had grain enough
of their own to last over beyond the next harvest and sold enough oats to pay the taxes and meet their other needs. So Iván and his children
might have lived quite comfortably had it not been for a feud between him and his next-door neighbor, Limping Gabriel, the son of Gordéy
Ivánof.
As long as old Gordéy was alive and Iván's father was still able to manage the household, the peasants lived as neighbors should. If the women
of either house happened to want a sieve or a tub, or the men required a sack, or if a cart-wheel got broken and could not be mended at once,
they used to send to the other house, and helped each other in neighborly fashion. When a calf strayed into the neighbor's thrashing-ground,
they would just drive it out, and only say, "Don't let it get in again, our grain is lying there." And such things as locking up the barns and
outhouses, hiding things from one another, or backbiting were never thought of in those days.
That was in the fathers' time. When the sons came to be at the head of the families, everything changed.

New technology leads to bigger cities in the 1800s, the united states was still a very young nation, trying to solidify its identity. the industrial revolution began in great britain, a fast development of society following the introduction of machines. the united states was slower than great britain to fully embrace the changes. yet key technological developments caused a rapid growth in american urban areas. better farming methods and tools in the 1800s increased food production. americans were able to grow enough food for their families as well as to sell. the abundance caused food prices to fall. the expansion of cotton and the growth of textile factories in northern states produce the first wave of american industry. more people turned to work in northern factories as a way to support their families. thousands of immigrants to the united states also settled in or near port cities, looking for work. even today, the need for work is a common reason people move to urban areas. as a result, cities grew in numbers of people and physical space. as more people and businesses moved in, they needed buildings for living and working. they needed ways to move around the city. we call this process urbanization. in 1820, the united states had only a few cities of 10,000 residents or more. about seven percent of u.s. residents lived in urban areas. the number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the northeast and midwest. by 1860, about 20 percent lived in cities. philadelphia and new york city were the most populated cities in 1860 and would soon reach one million residents. the urbanization of the united states quickened due to technology improvements. without innovations in food production, the factories could not have grown so quickly. the trend quickened after 1860 and continued throughout the 21st century as well. by 2007, more americans lived in or near cities than they did in rural areas. select a sentence from the body of this article that can be removed without affecting the author's explanation. place the sentence in quotes and explain why it is an unnecessary detail.
