Animal Intelligence: The Minds of Crows and Dolphins
For many years, scientists believed that only humans had the ability to think logically and use tools. However, recent studies on animal intelligence have shown that both crows and dolphins possess remarkable cognitive skills that challenge this traditional view.
Crows, in particular, have surprised researchers with their advanced problem-solving abilities. In one famous experiment, a crow named Betty was placed in a room with a straight piece of wire and a small bucket of food inside a glass tube. The food was too deep to reach with her beak. Betty independently bent the wire into a hook shape and used it to pull the food out. This demonstrated an understanding of cause and effect, as well as the ability to create tools without prior training.
Similarly, dolphins are widely known for their large brains and complex social structures. Marine biologists have discovered that dolphins use a sophisticated system of clicks and whistles to communicate with one another. These sounds are not just random noises; they function much like a language. Each dolphin even has a unique "signature whistle," which acts like a personal name to identify themselves to others in their pod. Furthermore, dolphins have been frequently observed working together to catch fish, showing advanced teamwork and planning.
While crows and dolphins live in completely different environments, their intelligence shares common traits. Both species can adapt to new situations, communicate effectively, and solve complex problems. These discoveries suggest that high levels of intelligence can evolve in various forms across the animal kingdom.
According to paragraph 1, what did scientists traditionally believe about intelligence?
What did the crow named Betty do to solve her problem in the experiment?
She broke the glass tube and used her beak to get the food.
What is the primary purpose of a dolphin's "signature whistle"?
What is the main conclusion drawn at the end of the passage?

Some people think teenagers are too young to run a class while still being students, but that is not true. In a new government scheme, sixteen-year-olds are already helping to teach lessons to primary school children, since the scheme allows school leavers to as teaching assistants in local primary schools. Head teachers say the extra support is welcomed. New rules were recently introduced allowing primary school teachers more time during the school day to focus on their lessons properly before each class begins, even though this sometimes leaves less time for actual teaching. To fill this gap, teenagers now step in instead of the missing teachers. They complete a two-year course starting at age fourteen, which gives them a valuable in their careers. Supporters call this a fair opportunity for young people. The government believes that about 18,000 teenagers could get jobs in this , although many people still doubt whether such young teenagers can really manage a full class of children.

The invention of the modern microwave oven occurred completely by accident during a routine scientific experiment. In 1945, a talented American engineer named Percy Spencer was working on complex radar equipment for a large military organization. While he was carefully testing a new vacuum tube, he suddenly noticed that a solid chocolate bar in his pocket had completely melted. Because he was incredibly curious about this strange phenomenon, Spencer decided to run several more experiments using different types of food. First, he successfully popped dry popcorn kernels, and then he managed to cook a raw egg until it suddenly exploded. Spencer quickly realized that the invisible radio waves were generating heat directly inside the food itself without any fire. Shortly after these successful initial tests, his engineering company finally built the world's first commercial microwave oven in 1947. This original machine was nearly two meters tall, and it weighed over three hundred kilograms, making it entirely unsuitable for regular home kitchens. However, as electronic technology gradually improved over the next two decades, engineers managed to design much smaller and significantly cheaper versions. By the late 1970s, the modern microwave had successfully become an extremely popular appliance in millions of households worldwide. Today, this incredibly convenient device allows busy families to easily prepare hot meals in just a few short minutes.
Spencer wanted to invent a new machine for cooking food in 1945.
