What is the theme of this passage?

Whatever you do,dont challenge a chimpanzee named Ayumu to a number memory game. In 2007, Ayumu became famous for his lightning speed at a game that goes like this: A player views a computer screen where the numbers 1 through 9 appear briefly at once and then turn to white squares. The player then taps the squares where the numbers had been,in order from 1 to 9. People can do it. But no human competitor has ever completed the game faster or more accurately than Ayumu the chimp. For almost five years Ayumu remains undefeated. Psychologist Nicholas Humphrey of Darwin College at Cambridge University in England now thinks he knows the secret behind the chimp s ability. Humphrey suspects Ayumu s brain may have a condition that allows the chimp to see numbers as colors. This would mean that Ayumu may see a color glow after the number disappears. Then,instead of remembering the numbers,he remembers a sequence of colors, each associated with a number. The condition that Humphrey believes Ayumu may have is called synesthesia. Humans with synesthesia may associate numbers and letters with colors. For example,a person may see the number "5"as the color blue. Until now,scientists had assumed only humans could have synesthesia. Humphrey found the inspiration for his idea at a 2011 scientific conference. There, he heard a presentation about Ayumu s memory abilities and another talk about synesthesia. He then put the two ideas together. Not everyone is convinced that Humphrey is correct. Primatologist Tetsuro Matsuzawa of the Primate Research Institute at Kyoto University in Japan has spent decades studying the amazing memories of chimpanzees, including Ayumu. He maintains that chimps simply have faster memory recall than people.

What is Ayumu famous for?

Why did Robby go back to the hot dog seller?

Which word best describes the homeless man?

It was a beautiful day for sightseeing around downtown Portland. We were on our day off and out for some fun. The weather was perfect for a picnic,so when lunch time came,we set our sights on a small park in town. Since we all had different tastes,we decided to split up,get what each of us wanted, and meet back on the grass in a few minutes. When my friends Robby headed for a hot dog stand, I decided to keep her company. We watched the seller put together the perfect hot dog,just the way Robby wanted it. But when she took out her money to pay him,the man surprised us. "It looks a bit smaller on the cool side, "he said, "so never mind paying me. This will be my freebie of the day. " We said our thanks,joined our friends in the park,and dug into our food. But as we talked and ate,I noticed a man sitting alone nearby,looking at us. I could tell that he hadn t showered for days. Another homeless person,I thought,like all the others you see in cities. I didn t pay much more attention than that. We finished eating and decided to head -off for more sightseeing. But when Robby and I went to the garbage can to throw away my lunch bag, I heard a strong voice, " There isn t any food in that bag,is there?" It was the man who had been watching us. I didn t know what to say. "No,I ate it already. " "Oh,"was his only answer, with no shame in his voice at all. He was obviously hungry, couldn t bear to see anything thrown away, and was used to asking this question. I felt bad for the man,but I didnt know what I could do. That s when Robby said, "I’ll be right back. Please wait for me a minute," and ran off. I watched curiously as she went across to the hot dog stand. Then I realized what she was doing. She bought a hot dog,crossed back to the garbage can,and gave the hungry man the food. When she came back to us, Robby said simply," I was just passing on the kindness that someone gave to me. "

Why did the seller offer Robby a free hot dog?
