Reading

1. The author's attitude towards history seems to be

Correct answer: C

Rationale: The passage's overall tone highlights the value and utility of history, showcasing its potential to inspire and guide us, suggesting an optimistic and encouraging view.

2. Two coherent light waves with a slight phase difference interfere. What determines the resulting intensity of the combined wave?

Correct answer: A

Rationale: The intensity of the resulting wave depends on the individual intensities and the phase difference between the interfering waves. Constructive interference leads to higher intensity, while destructive interference leads to lower intensity.

3. The largest bone in the human body is the:

Correct answer: A

Rationale: The correct answer is A: Femur (thigh bone). The femur is the longest and strongest bone in the human body, located in the thigh region. It plays a crucial role in supporting the body's weight and facilitating movement. The tibia (B) is commonly known as the shin bone and is located below the femur. The humerus (C) is the upper arm bone, and the scapula (D) is the shoulder blade. However, neither of these bones is the largest in the human body. Understanding the anatomy of the skeletal system is essential for identifying the largest bone in the body, which is the femur.

4. Which structure in the respiratory system serves as the "windpipe" that conducts air from the larynx to the bronchi?

Correct answer: A

Rationale: The correct answer is A: Trachea. The trachea, also known as the windpipe, is a tube-like structure in the respiratory system that connects the larynx to the bronchi. It serves as the main airway for the passage of air into and out of the lungs. The larynx is commonly known as the voice box and is responsible for producing sound. The bronchi are the two branches that stem from the trachea and lead to the lungs, where they further divide into smaller airways. The alveoli are tiny air sacs in the lungs where gas exchange occurs. Therefore, the trachea is the correct answer as it directly conducts air from the larynx to the bronchi.

5. What is the relationship between mass and inertia?

Correct answer: a

Rationale: Mass is a measure of the amount of matter in an object and is directly related to its inertia.

6. B cells in the immune system are responsible for:

Correct answer: B

Rationale: B cells in the immune system are responsible for producing antibodies specific to a pathogen. This is because B cells are a type of white blood cell that play a crucial role in the adaptive immune response. When a B cell encounters a specific pathogen, it differentiates into plasma cells that produce antibodies targeted against that particular pathogen. These antibodies then tag the pathogen for destruction by other immune cells. B cells do not directly attack and engulf pathogens like phagocytes, nor do they destroy infected body cells like cytotoxic T cells. Therefore, option B is the correct answer as it accurately reflects the primary function of B cells in the immune system.
