Q.2. Read the following passage carefully and answer the questions that follow:
The human brain is a complex and remarkable organ that plays a crucial role in our thoughts, emotions, and behaviors. It consists of billions of interconnected neurons that work together to process information and carry out various functions. Understanding the brain and its functions is a topic of ongoing scientific research and exploration.

One of the key features of the brain is its plasticity, also known as neuroplasticity. Neuroplasticity refers to the brain's ability to change and adapt throughout life. It allows the brain to reorganize itself in response to new experiences, learning, and even injuries. This remarkable capacity for adaptation is what enables us to learn new skills, form memories, and recover from brain injuries.

Another important aspect of the brain is the division of labor between its different regions. Each region of the brain has specialized functions and is responsible for specific cognitive processes and behaviors. For example, the frontal lobe is involved in decision-making and problem-solving, while the temporal lobe plays a role in memory and auditory processing.

The brain also relies on chemical messengers called neurotransmitters to transmit signals between neurons. Neurotransmitters, such as dopamine and serotonin, are involved in regulating mood, emotions, and various bodily functions. Imbalances in neurotransmitter levels have been linked to mental health disorders, such as depression and anxiety.

However, there is still much to uncover about the intricacies of the brain. Many questions remain unanswered, such as the exact mechanisms of consciousness and the nature of human intelligence.

Q.3. Read the following passage carefully and answer the questions that follow:
The human brain is a complex organ that is responsible for a wide range of functions. It is composed of billions of neurons that communicate with each other through electrical and chemical signals. One of the key functions of the brain is to process and interpret information from the environment, allowing us to perceive and interact with the world around us.

One common misconception about the brain is that humans only use 10% of their brain capacity. This notion has been popularized in movies and books, but it is not supported by scientific evidence. In reality, every part of the brain has a specific function, and even small injuries to certain areas can have significant effects on our abilities.

Another interesting aspect of the brain is its ability to change and adapt. This phenomenon is known as neuroplasticity. Research has shown that the brain can reorganize itself in response to new experiences or changes in the environment. This plasticity is particularly evident in children, whose brains are more flexible and capable of forming new connections.

Memory is another important function of the brain. There are different types of memory, including short-term memory and long-term memory. Short-term memory allows us to hold and manipulate information for a brief period of time, while long-term memory involves the storage and retrieval of information over a longer period. Memory is not a fixed entity and can be influenced by various factors, such as attention, rehearsal, and emotional significance.

In conclusion, the human brain is a remarkable organ that plays a vital role in our daily lives. It is responsible for processing information, adapting to new experiences, and storing memories.
