Ammy is a college student. She wrote in her diary:
For breakfast, I usually have cereal and milk and a piece of fruit – an apple or a banana. If I wake up really hungry then
I’ll also have a piece of bread with jam on it. Sometimes I’ll have eggs, an omelet with cheese and maybe ham. And if
I’m late for class, I’ll just have a cup of coffee.
I don’t have a lot of time in between classes this semester, so for lunch I will typically grab something quick to eat, like a slice of pizza. Or a sandwich, either turkey or bacon with lettuce and tomatoes. Despite the junk food at lunch time, I try to keep healthy by having another piece of fruit or a granola bar for a snack in the middle of the afternoon.
Now, answer: In the text read Ann talks about:
The Irish hollowed out turnips and placed a light inside to keep away the bad Jack. As the legend says, Jack was a man who tricked the devil and after Jack had died he was allowed neither in heaven nor in hell. With a lantern in his hand he began to search for a resting place on Earth. This was the original Jack-o-Lantern. Since celebration came to America from Ireland (Scotland and Wales) people used pumpkins because they were bigger and easier to hollow out than turnips.
This text makes reference to a custom of one of the best-known festivals in the United States:
Text from question:
Fox and the grapes
It was a very hot and sunny afternoon. A fox, which had been hunting the whole day, was very thirsty. 'How I wish there
was some water, the fox thought to himself.
Just then, he saw bunches of fat and juicy grapes hanging from a vine above his head. The grapes looked ripe and ready to
burst with juice.
'Oh, my! Oh, my!' the fox said as his mouth began to water. 'Sweet grape juice, quench my thirst!'
The fox stood on tiptoe and stretched as high as he could, but the grapes were out of his reach. Not about to give up, the
fox walked back a short distance and took a running leap at the grapes. Again, he could not reach the grapes.
The fox jumped and leapt, again and again, but each time he could not reach the grapes. Until, at last, the fox was tired
and thirstier than ever. 'What a fool I am!' said the fox furiously. 'These grapes are sour and not fit for eating. Why would
I want them anyway?'

TEXTO III
Nobel Prize in Chemistry Awarded to 3 Scientists for Exploring the Nanoworld1
Three pioneering scientists, Moungi G. Bawendi, Louis E. Brus, and Alexei I. Ekimov, have been honored with the Nobel Prize in Chemistry for their groundbreaking work on quantum dots, which are semiconductor particles small enough to significantly alter their electron behavior. These quantum dots, comprising only a few thousand atoms, have applications ranging from enhancing LED lights to potential advancements in solar cells and quantum information encryption.
Semiconductors, essential in powering our modern electronics, traditionally consist of large molecular-level crystals. However, quantum dots are vastly smaller. To provide perspective, the Nobel Foundation likened the size difference between a quantum dot and a soccer ball to that between a soccer ball and the Earth.
These nanoscale dots are now utilized in LED lights to refine color and in televisions to improve resolution. Additionally, they hold potential in the biomedical field, such as in cancer tissue removal. Despite initial skepticism regarding the feasibility of creating such __________________ minuscule particles, this year’s laureates prevailed. Their achievement, particularly Bawendi’s method for crafting specific size, highquality nanoparticles, has propelled technological applications like QLED screens and various imaging in biochemistry and medicine.
However, the announcement of this year's laureates was surrounded by unusual circumstances. Before the official statement from the Royal Swedish Academy of Sciences, Swedish media sources leaked the information, citing an email mistakenly sent early from the Academy.
About the winners: Dr. Bawendi, a professor at MIT and a former postdoc under Dr. Brus, was born in France. Dr. Brus, a professor emeritus at Columbia University, was born in the U.S. Dr. Ekimov, once the chief scientist at Nanocrystals Technology in New York, was born in the former Soviet Union.
Their achievements in the realm of nanotechnology have enabled the exploration of distinct properties of extremely small matter, and have had profound implications in various technological domains. Their efforts in the 1980s, which led to the creation of quantum dots, needed further refinement before technological applications could be realized. Their work is regarded as monumental in bridging theoretical concepts with real-world applications. According to the American Chemical Society’s president, Judith Giordan, their discoveries are not just of academic interest but aim to benefit humanity at large.
Upon winning the prize, Dr. Bawendi expressed surprise and honor, emphasizing the significance of sharing the award with his mentor, Dr. Brus. Other notable winners this year include Katalin Karikó and Drew Weissman for their contributions to Covid-19 vaccine development in the Physiology or Medicine category, and Pierre Agostini, Ferenc Krausz, and Anne L’Huillier in Physics.
