Q: Read the following article and answer the question. Article: Erden Eruc has been rowing across the Pacific Ocean in a rowboat since he left California on July 10, 2007. He has been heading for Australia with only birds, fish, and sharks ever since. Crossing the Pacific is only part of his journey. Eruc has decided to go all the way around the world using his own energy. He will row, bike, walk and climb the world without help from any motors at all. His plan includes climbing the tallest peak on six of the continents along the way. For the first part of his trip, he bicycled 5,546 miles from Seattle, Washington to Mount McKinley in Alaska and back, walked 67 miles to base camp and climbed 20,320 feet to McKinley's peak. Now in the second part of his adventure , he is rowing to Australia. Why would he try to go around the world this way? He explains that he wants to encourage kids to dream their dreams and get to their own goals. He wants to show kids that there might be hard parts along the way, and sometimes they might not even get to that final goal. But they can have adventures and learn a lot along the way. When his trip around the world takes him across land, he enjoys meeting people---especially children. He has already visited many schools and shared his story. Eruc encourages all kids to set their eyes on a goal and not give up. He says, "with goals, we will make progress, and we will be farther along than when we started, even if we don't get to some goals. That's called life!" Question: We can learn from the passage that Eruc _ during his adventure. Answer:
A:
