Read the poems below and answer the question that follows.War Is Kindby Stephen CraneDo not weep, maiden, for war is kind.Because your lover threw wild hands toward the skyAnd the affrighted steed ran on alone,Do not weep.War is kind.Hoarse, booming drums of the regiment,Little souls who thirst for fight,These men were born to drill and die.The unexplained glory files above them,Great is the battle-god, great, and his kingdomA field where a thousand corpses lie.Do not weep, babe, for war is kind.Because your father tumbled in the yellow trenches,Raged at his breast, gulped and died,Do not weep.War is kind.Swift blazing flag of the regiment,Eagle with crest of red and gold,These men were born to drill and die.Point for them the virtue of the slaughter,Make plain to them the excellence of killingAnd a field where a thousand corpses lie.Mother whose heart hung humble as a buttonOn the bright splendid shroud of your son,Do not weep.War is kind.Mending Wallby Robert FrostSomething there is that doesnt love a wall,That sends the frozen-ground-swell under it,And spills the upper boulders in the sun,And makes gaps even two can pass abreast.The work of hunters is another thing:I have come after them and made repairWhere they have left not one stone on a stone,But they would have the rabbit out of hiding,To please the yelping dogs. The gaps I mean,No one has seen them made or heard them made,But at spring mending-time we find them there.I let my neighbor know beyond the hill;And on a day we meet to walk the lineAnd set the wall between us once again.We keep the wall between us as we go.To each the boulders that have fallen to each.And some are loaves and some so nearly ballsWe have to use a spell to make them balance:Stay where you are until our backs are turned!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 acrossAnd 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 wonderIf I could put a notion in his head:Why do they make good neighbors? Isnt itWhere there are cows?But here there are no cows.Before I built a wall Id ask to knowWhat I was walling in or walling out,And to whom I was like to give offence.Something there is that doesnt love a wall,That wants it down. I could say Elves to him,But its not elves exactly, and Id ratherHe said it for himself. I see him thereBringing a stone grasped firmly by the topIn each hand, like an old-stone savage armed.He moves in darkness as it seems to meNot of woods only and the shade of trees.He will not go behind his fathers saying,And he likes having thought of it so wellHe says again, Good fences make good neighbors.These two poems have which of the following in common?A.apostropheB.third-person point of viewC.first-person point of viewD.colloquialismsE.imagery PART B: How does the phrase sick in his heart contribute to the tone of the entire passage?A. by creating conflict between Stephen and the other boys to support a tense toneB. by adding detail to Stephens character to support a melancholy toneC. by illustrating Stephens inner thoughts to support a serious toneD. by describing characters who are suspicious of each other to support an angrytone pls help will mark brainliest how did our solar system form ? draw and label a diagram of the water cycle using the words below.GravitySunlightEvaporationCondensationPrecipitationwater cycleTranspirationRunoff Mr. Jones has fives eats on the schools trip to Grand Canyon for his students.
