Select the correct text in the passage. which sentences in this excerpt from ernest shackleton's south! suggest that the author is writing a memoir? the outlook was disappointing. i looked down a sheer precipice to a chaos of crumpled ice 1500 ft. below. there was no way down for us. the country to the east was a great snow upland, sloping upwards for a distance of seven or eight miles to a height of over 4000 ft. to the north it fell away steeply in glaciers into the bays, and to the south it was broken by huge outfalls from the inland ice-sheet. our path lay between the glaciers and the outfalls, but first we had to descend from the ridge on which we stood. cutting steps with the adze, we moved in a lateral direction round the base of a dolomite, which blocked our view to the north. the same precipice confronted us. away to the north-east there appeared to be a snow-slope that might give a path to the lower country, and so we retraced our steps down the long slope that had taken us three hours to climb. we were at the bottom in an hour. we were now feeling the strain of the unaccustomed marching. we had done little walking since january and our muscles were out of tune. skirting the base of the mountain above us, we came to a gigantic bergschrund, a mile and a half long and 1000 ft. deep. this tremendous gully, cut in the snow and ice by the fierce winds blowing round the mountain, was semicircular in form, and it ended in a gentle incline. we passed through it, under the towering precipice of ice, and at the far end we had another meal and a short rest. this was at 12: 30 p. m. half a pot of steaming bovril ration warmed us up, and when we marched again ice-inclines at angles of 45 degrees did not look quite as formidable as before.
