Diving InIt was a hot day at the beach, so why did the ocean feel like ice? Carol wanted to cool off, but she had only managed to wade in up to her ankles. Her feet were nearly numb from the cold water."Wow, it's freezing today," said her sister, Pauline. They stood side by side, half-shivering in the water and half-baking in the sun.Carol noticed the windsurfers in the distance. Of course, she thought. They're wearing wetsuits. But then she saw an old man swimming nearby, wearing only his trunks and a swim cap. A few more courageous heads bobbed up and down in the chilly sea."Okay, that's it," Pauline said. "I'm doing it." She took a deep breath, ran into the surf, and dived into a large, breaking wave. She emerged farther out, a big grin on her face.Carol inched forward. As she did, her shins, then her knees, and then her thighs stung from the cold. She noticed that her feet felt okay now, but when the water touched her stomach, she shrieked. The breakers now splashed water across her back and shoulders."It's too cold!" Carol shouted. "I'm going back!"Then she froze. She saw a big wave approaching. There was no time to turn back; she was in too deep. She watched with dread as the crest swelled above her head. She closed her eyes and dunked beneath the wave.A freezing sensation enveloped her for an instant, but then she felt fine. Refreshed, even.Finally, she swam out to her sister.Which of the following best describes the main theme or lesson of the story?Going through something painful makes you stronger.Sometimes it's better when unpleasant experiences happen quickly.Not everybody can be brave.Submit

Nothing can describe the confusion of thought which I felt when I sank into the water. Though I swam very well, I could not deliver myself from the waves so as to draw breath, till that wave having driven me, or rather carried me, a vast way on towards the shore, and having spent itself, went back, and left me upon the land almost dry, but half dead with the water I took in. I had so much presence of mind, as well as breath left, that seeing myself nearer the mainland than I expected, I got upon my feet, and endeavored to make on towards the land as fast as I could before another wave should return and take me up again. However, I soon found it was impossible to avoid it; for I saw the sea come after me as high as a great hill, and as furious as an enemy, which I had no means or strength to contend with: my business was to hold my breath, and raise myself upon the water if I could. By swimming, I could preserve my breathing, and pilot myself towards the shore, if possible. My greatest concern now being that the sea, as it would carry me a great way towards the shore when it came on, might not carry me back again with it when it gave back towards the sea.     The wave that came upon me again buried me at once twenty or thirty feet deep in its own body. I could feel myself carried with a mighty force and swiftness towards the shore a very great way, but I held my breath, and assisted myself to swim still forward with all my might. I was ready to burst with holding my breath, when, as I felt myself rising up, so, to my immediate relief, I found my head and hands shoot out above the surface of the water. Though it was not two seconds of time that I could keep myself so, yet it relieved me greatly, gave me breath, and new courage. I was covered again with water a good while, but not so long but I held it out; and finding the water had spent itself, and began to return, I struck forward against the return of the waves, and felt ground again with my feet. I stood still a few moments to recover breath, and till the waters went from me, and then took to my heels and ran with what strength I had further towards the shore. But neither would this deliver me from the fury of the sea, which came pouring in after me again; and twice more I was lifted up by the waves and carried forward as before, the shore being very flat.     The last time of these two had well-nigh been fatal to me, for the sea having hurried me along as before, landed me, or rather dashed me, against a piece of rock, and that with such force, that it left me senseless, and indeed helpless, as to my own deliverance. The blow taking my side and breast, beat the breath as it were quite out of my body; and had it returned again immediately, I must have been strangled in the water; but I recovered a little before the return of the waves. Seeing I should be covered again with the water, I resolved to hold fast by a piece of the rock, and so to hold my breath, if possible, till the wave went back. Now, as the waves were not so high as at first, being nearer land, I held my hold till the wave abated, and then fetched another run, which brought me so near the shore that the next wave, though it went over me, did not so swallow me up as to carry me away. The next run I took, I got to the mainland, where, to my great comfort, I clambered up the cliffs of the shore and sat me down upon the grass, free from danger and quite out of the reach of the water.3Select ALL the correct answers.Which two statements should be included in a summary of the passage?
