Unit 21:
The Twins
Katie and Alice were twins. They were so alike that few people could tell the siblings apart. They were almost like clones. They even used the same colloquial language as each other. They were best friends.
But the twins’ attributes were not all identical. Alice liked humanities, and Katie was a good linguist. One summer, Katie decided to be a participant at a summer camp in France. Alice wasn’t interested in the French language, so she didn’t go. But she felt angry that Katie wanted to spend the summer away from her.
Two months later, Katie returned. Alice dashed to the airport to greet her sister. But when Alice saw Katie, she was astounded. Katie was now bilingual, and she looked completely different! She was wearing nice clothes, cosmetics and looked skinnier. Alice felt very messy next to her. She was just wearing a fluorescent t-shirt, and her hair had knots in it.
When Alice asked Katie about France, Katie was vague and didn’t say much. It made Alice furious and filled her with disgust because in the past they’d always told each other everything. Now there was a huge gulf between them. Over the weeks, the sisters spoke even less.
Two months later, it was the twins’ birthday. All their lives, they’d had a ritual. Before their birthday, they’d talk all night long. That night, Alice came into Katie’s bedroom.
“I’m sorry I haven’t spoken much lately,” Katie said.
“I understand. You have new friends now,” said Alice, angrily.
Katie said, “My French friends don’t write much nowadays. For a while, I thought they were more exciting than my friends at home. But I was wrong. You’re my sister, and you’ll always be my best friend.”
Alice said, “I’m sorry, too. I wanted our relationship to stay the same forever. But it’s totally plausible for twins to have different interests. We can still be best friends without being together all the time.”

Unit 22:
The New Bioco
Jack got a new job at a biotechnology company called Bioco. Bioco manufactured drugs to treat diabetes and high cholesterol. Jack’s job was to use a tiny mechanism to get nectar from flowers. The nectar was a main ingredient in the drugs. Jack liked his job, and he thought that Bioco was a caring company. However, Jack soon learned that the company wasn’t as kind as he first thought.
Bioco’s motto was “Make the Earth a Better Place.” However, this motto was deceptive. The company actually did a number of really bad things to the environment. The company produced a lot of smog and harmful acid. Bioco poured the acid in a nearby river, which caused erosion and made fish prone to illness.
After a few weeks at the new job, Jack saw all the bad things Bioco was doing. He had always had strong ethics, and he knew he had to do something. One day, while the Bioco workers were eating in the cafeteria, Jack stood up and gave a speech. He said, “My fellow coworkers, I know you have all seen the evil things our company is doing. I have a notion that we can fix them if we form a coalition. We can go to the administration and tell them we’ll quit if they don’t eliminate the problems. They’ll have no choice but to listen to us.”
Jack explained what they were to do. His coworkers liked his explicit plan. They went to the administrative offices and demanded that Bioco stop damaging the environment, or they all would quit. One supervisor said to them, “Thank you for being straightforward about this issue. Since I can’t afford to lose all of you workers, I guess we’ll just have to fix things.”
Jack, his supervisor, and his coworkers spent the next month designing a new framework for the company. They cleaned up the acid from the river and minimized the amount of air pollution the company released. At last, the company motto became apt.
Unit 25:
The Man and the Monkey
While flying over a jungle, a wealthy executive’s private plane crashed. Some of the crew were hurt, so the pilot decided to stay with them and wait for help. The arrogant executive, though, didn’t care about the welfare of the pilot and crew. Rather, he thought he could walkout of the jungle and find a town to stay in.
He followed a trail through a canyon and along a creek. The jungle was actually very stunning. If the arrogant executive had stopped to look around, he might have perceived the jungle’s beauty. But he was in a nasty mood and had no care for the aesthetic value of the jungle. He continued to walk up the steep incline of the jungle’s hills.
Soon, he was lost. Several days passed, and fatigue and hunger weakened him. He was very tired and afraid.
Just then, a monkey came out of the trees. It was carrying a twig covered in honey. It walked up to a mound where termites lived. He then used the twig like a drill to make a hole in the mound. Then very carefully, it removed the twig from the hole. The sticky twig was covered with termites.
Instead of eating the bugs, the monkey offered them to the executive, but he didn’t want what the monkey offered. He shouted at the monkey, “Get away from me, you stupid primate!”
The executive’s stereotype of the monkey was wrong. The monkey was not stupid. It knew how to find food, whereas the executive did not. He refused the help of the monkey, thereby leaving himself to starve.
When the executive was finally found, he was very skinny and sick. He had not eaten for a very longtime. Because he held a bias against the primitive ways of the monkey, he had gone hungry and almost died. The executive didn’t understand that it was his arrogant attitude that had caused all of his problems.
Unit 23:
How Comet Got His Tail
A solitary rock roamed through the cold gloom of outer space. It slowly drifted through the debris of broken asteroids with a feeling of sadness. In the vast and beautiful galaxy, it was only a tiny rock. It felt like an insignificant atom.
In its journeys it encountered many amazing objects. It flew by beautiful crescent moons that were covered with craters and moon dust.
“Why can’t I be as beautiful as them?” it thought.
The rock passed a gigantic planet. The sphere had a circumference hundreds of times larger than the breadth of the small rock.
“Why can’t I be as large as that?” it wondered.
The rock was filled with despair. It was surrounded by beauty and greatness, yet it was just a small and ugly fragment of rock.
One day, it approached the area of an astronomical star.
“What’s wrong?” the star asked.
“Oh, I wish I had a higher status in the galaxy. All the other objects are so beautiful and large,” the rock replied. “But I’m just an ugly rock.”
The star considered the problem. At last it said, “You don’t have to worry anymore. I think I can help.” The star radiated its light brighter and hotter than it had ever done before. “Come a little closer,” the star said to the rock.
The rock drifted closer to the star. Suddenly, the ice that was embedded in the rock’s tiny cracks melted and became steam. Then the steam extended behind the comet to form a brilliant tail. The tail shined with all the colors of the spectrum.
The little rock had become a beautiful comet. It looked so amazing. It realized that the star helped it change its appearance. “Thank you,” the comet said and then flew away with its new beautiful tail following behind it like a galactic cape.

Unit 24:
The Resourceful Landlord
A kind landlord was afraid that he would lose his apartment building. He needed to make some mandatory repairs to the old building, or his tenants would have to leave by the end of the month. Without tenants to lease the rooms, the landlord would be unable to pay his mortgage. He’d be bankrupt, and the bank would take his building.
But he didn’t have the money whereby he could employ the personnel needed to make the repairs. It would seem like he did not want to conform to the city’s codes before the forthcoming inspection. He had requested an extension, but it was denied by the city.
He held a meeting with his tenants and explained the unfortunate situation. “If the building does not meet the appropriate standards for safety and hygiene,” he said, “the city will expel everyone.”
The tenants were all sad for the kind old man.
“Maybe we can help,” the hairdresser who lived on the first floor stated. The other tenants agreed.
One tenant had worked for the city’s utilities. He knew a lot about plumbing, so that’s how he helped. Another tenant was a carpenter; he mended the holes in the floor and walls. Others cleaned the building from top to bottom so that it was more hygienic. They even furnished some of the apartments with new beds, dressers, and chairs. When they were done, all of the people dispersed, and the landlord went home to rest.
When the deadline of the inspection arrived, the apartment building was hygienic and safe. The landlord couldn’t believe it. His old building now looked like one of the trendiest buildings in town. The building passed its inspection, and the landlord and the tenants had a big party.
“Thank you all so much,” the landlord said during the party. “I could never have done it by myself. But by working together, we now all have a beautiful place to live.”

They were given wings and instructed to orbit the Earth. After successful flights, the boys officially became men. Cosmo certainly wanted to be a man, but he was scared. He went to the oracle of a god named Dano. Cosmo said, “I’m not sure I can make such a long trip. What if I get tired? What if my strength stalls, and I can’t stay in the air. I’ll crash and die!”
Dano replied, “Don’t be afraid. You have all the relevant skills in your personal inventory that have been building up over the years. To ease your worry, let me tell you a little about what will happen tomorrow. You’ll begin over Africa. You’ll keep flying north until you come to the Himalayas. The mountaintops will look like small loaves of bread at such a high distance. The rivers of the world will look like pieces of blue string that cross the globe. Keep your body horizontal when flying against the winds of the Pacific Ocean. Keep your eyes open and enjoy the beauty of the Earth. You will be fine, you’ll see.”
Cosmo replied, “Thanks for the overview of my journey, I’ll do my best.”
The next morning, Cosmo was provided with a divine set of wings and sent on his way. He flapped his wings and went high above the Earth. He flew over mountains, oceans, and glaciers. After a while, his inward thoughts were no longer about falling. He was actually having fun! He began to hum a song as he enjoyed the view. When he reached home, his tribe was there to greet him.
The chief said, “On behalf of the tribe, I declare you a man. We’re proud of you, Cosmo!”
Cosmo was proud of himself, too.

The First Organ Transplant
In 1954, a man named Richard was dying of kidney disease. He wouldn’t survive for long unless he got a new kidney right away. Richard’s twin brother, Robert, was willing to donate one of his kidneys to his dying brother. At the time, however, no doctor had ever performed a successful internal organ transplant. The idea of taking an organ out of one person and putting it into another was just a fantasy. But the brothers decided to be brave and found a doctor who could make organ transplants a reality.
Since Richard and Robert were twins, their heredity was identical. They had the exact same biological traits. Even their kidneys were identical on the cellular level. Therefore, Robert’s working kidney could be substituted for Richard’s bad one. Richard’s body could adapt to the new organ if the operation was done correctly.
The twins went to Dr. Murray, who was a pioneer of new surgical methods. His dynamic team of surgeons performed the transplant. Dr. Murray made sure his surgeons followed a rigid sequence of directions so that no mistakes were made. First, they made a minimal cut in Richard’s side and removed the bad kidney. Then, they made another small cut in Robert’s side, removed his kidney, and transferred it into Richard’s body. Finally, they sewed up the respective cuts. The entire operation only took about one hour.
After the surgery, it was clear that both brothers were going to be OK. The operation was confirmed a success. Richard’s new kidney worked great! Doctors prescribed medicine for the pain caused by the surgery. Since Richard was still weak, he used physical therapy to revive his strength. At last, Richard’s transition into a healthy, happy person was complete.
Dr. Murray became a hero in the medical world. His success gave other doctors confidence to try organ transplants themselves. Now, doctors perform life-saving transplants and surgeries every day.
