Read the excerpt from muir's essay "calypso borealis" and answer the question. [5] how long i sat beside calypso i don't know. hunger and weariness vanished, and only after the sun was low in the west i splashed on through the swamp, strong and exhilarated as if never more to feel any mortal care. at length i saw maple woods on a hill and found a log house. i was gladly received. "where ha ye come fra? the swamp, that awfu' swamp. what were ye doin' there? " etc. "mony a puir body has been lost in that muckle, cauld, dreary bog and never been found." when i told her i had entered it in search of plants and had been in it all day, she wondered how plants could draw me to these awful places, and said, "it's god's mercy ye ever got out." examine the details muir includes in this paragraph. which statement accurately explains how muir's response to nature compares to the log house owner's response? he is enthusiastic and in awe while she is doubtful and fearful. muir cautiously admires whereas the lady shows religious dedication. the lady is more interested in the bog while muir is fascinated by plants. they both admire nature—its intense dangers and its true treasures.

"when did you come, rahmun? " i asked him. "last evening," he said, "i was released from jail." the words struck harsh upon my ears. i had never before talked with one who had wounded his fellow, and my heart shrank within itself when i realised this; for i felt that the day would have been better-omened had he not turned up.
