" we wear our fingers rough with handling them. oh, just another kind of out-door game, one on a side. it comes to little more: there where it is we do not need the wall: he is all pine and i am apple orchard. my apple trees will never get across and eat the cones under his pines, i tell him. he only says, “good fences make good neighbors." spring is the mischief in me, and i wonder if i could put a notion in his head: "why do they make good neighbors? isn't it where there are cows? but here there are no cows. before i built a wall i'd ask to know what i was walling in or walling out, and to whom i was like to give offence. . " a. the human desire for material gain b. the influence of financial constraints c. the positive effects of friendship d. the uncertain nature of human relations e. the futility of human yearning

Read the passage from sugar changed the world. but it is in india, where it was used as an offering in religious and magical ceremonies, that we have the first written record of sugar. long before the first pyramids were built in egypt, the ancient sumerians traded with the people of harappa and mohenjo daro, who lived along the indus river. unfortunately, we are still not able to read the writings left behind from those ancient cities. so the first documents telling us about life in that region come from a much later period. these hindu sacred teachings were probably first gathered together sometime between 1500 and 900 b.c., and were carefully memorized. only hundreds of years later were they finally written down. the hindu writings tell us of a religion in which fire was extremely important. people believed that the gods gave fire to human beings. yet fire was also a way for humans to reach the gods. by placing offerings in a special fire, a priest could turn them into smoke and send them on to the gods. five ingredients were selected for this special burning: milk, cheese, butter, honey, and sugar cane. which details would best fit in a summary of this passage? select two options.
