Example Input: Article: Columbus made four voyages to the west between 1492 and 1504 in his vain search for a sea route to Asia. The mystery of why he failed to find it haunted him and filled him with sadness. Wherever he went to Cuba, Puerto Rico, Jamaica, South America, Panama, down the coast of Central America--it was always the same story. Instead of golden palaces, there were grass huts and palm-leaf tents. Instead of silk-robed merchant princes, he found "Indians" who did not have so much as a shirt on their backs. When Columbus explored the West Indies in 1493,he heard tales of a fierce Indian tribe who literally devoured its defeated enemies after a battle. These people were called by many names in the area, including Calina, Canima, Carib, and Caniba. Columbus recorded the name of the American natives as Canibales in Spanish, a word which came to refer, within a few years, to any eater of human flesh. In the similar fashion, the word Caribbean, a title for the sea as well as for the region, came into English. At times Columbus knew that this new land was not China, not Japan, not the Spice Islands. He seemed to accept it as a part of the earth that the geographers of Europe had never heard of before. It was another world--and he called it exactly that--but Columbus also insisted until he died that land he had reached was an unknown part of Asia.

Example Input: Article: My father left me a treasure when he died. It wasn't a big house or a car. It wasn't cash or gold. In the eyes of the world my father died a poor man. He was a simple mechanic who worked hard to support his family. My father's treasure, rather, was in a thousand wonderful memories that he gave me over the course of his life. One particular one stood out in my mind today. I was just a boy playing in the backyard of a friend's house while my father spent the afternoon under the hood of an old car, trying to get it running again. It seemed to take hours and I wasn't sure whether he could bring the ancient car back to life again this time. At long last, though, he closed the hood and turned the key in the ignition . There was a sweet smile of satisfaction on his face as the engine started. There was a twinkle of joy in his eye when he shook his head. And there was a quiet hum of happiness in his voice as we drove back home that day. This memory made a home in my heart and became a priceless pearl for my soul to cherish. Time and time again, my father showed me that a kind life, a giving life and a heavenly life was created one choice at a time. Not all of his choices were the right ones, but most of them were. He did the best he could. He lived the best he could. And he helped to bring out the best in me, too. He once said to me, "It is lucky that all of your choices are driven by love and inspired by joy." As I look back into those memories my father left me, I realize that each one of them inspired me to live and to love. May all of your choices bring memories of happiness to those around you!
Answer: Memories of his father and himself.
Example Output: What was the most precious thing the author's father passed on to him?

Example Input: Article: Watch out, Yahoo.There's a search engine out there with super speed and accuracy.It's really cool. Google is the Web's largest search engine.In just two years it has gained a fame for surprising speed and accuracy, sending exactly what you're looking for in a second.The site now does this 40 million times a day--a number achieved without spending a penny on a TV or newspaper ad. Google doesn't need them. In the past six months alone, the site has won a Webby (the online version of the Oscar) for technical excellence, sets a new record for search engines by indexing a billion Web pages. Yahoo still has 10 times the audience, but Google consistently ranks first in customer satisfaction: 97% of users find what they're looking for most or all of the time."You see people smile when they use it, like they've found something no one else knows about," says Danny Sullivan, editor of an online newsletter. No one is smiling more than Larry Page, 27, and Sergey Brin, 26, who seem certain to become billionaires when the company goes public, probably sometime next year.They make a great comedy.When they first met as PhD students, the pair say, they found each other horrible--"I still find him horrible," adds Brin--but were driven together by a computer science project aimed at coming up with better ways of searching the Web. The idea behind Google is that traditional search engines are stupid.They think the connection is based on repetition; if you type in a request for Tiger Woods, say, you'll get websites listed according to how many times those words appear.Not only is this no guarantee of quality, but it's also open to bad use.If you own a Tiger fan site and want to lead more people to it, simply type his name thousands of times in the site's source code.
Answer: Google.

Which of the following wins greater customer satisfaction?
