1. What is the definition of the word haunt in the following passage?
- A. To levitate
- B. To constantly visit
- C. To terrorize
- D. To daunt
Correct answer: B
Rationale: In this context, 'haunt' means to constantly visit a place. Mr. Utterson is repeatedly going over the details of the situation in his mind, engaging with the problem persistently, as seen in the passage. The word does not imply levitation, terrorizing, or daunting in this context, making choices A, C, and D incorrect.
2. Which of the following pathologies is caused by a virus?
- A. Asthma
- B. Cystic Fibrosis
- C. Epiglottitis
- D. Influenza
Correct answer: D
Rationale: The correct answer is D, Influenza. Influenza is a viral infection caused by the influenza virus. Asthma and cystic fibrosis are not caused by viruses. Asthma is a chronic respiratory condition related to inflammation and airway constriction, while cystic fibrosis is a genetic disorder affecting the lungs and other organs. Epiglottitis is most commonly caused by bacteria, particularly Haemophilus influenzae type B, rather than a virus.
3. Which statement about white blood cells is true?
- A. B cells are responsible for antibody production.
- B. White blood cells are produced in the bone marrow before entering the bloodstream.
- C. Platelets, a specialized class of blood cells, function to clot blood and stop bleeding.
- D. The majority of white blood cells are active throughout life, providing immunity across all age groups.
Correct answer: A
Rationale: The correct answer is A: B cells, a type of white blood cell, are responsible for producing antibodies in response to pathogens. Antibodies play a crucial role in identifying and neutralizing foreign substances like bacteria and viruses in the body, aiding in the immune response and protecting against infections. This function is essential for maintaining a healthy immune system. White blood cells, including B cells, are produced in the bone marrow before entering the bloodstream. Platelets, not white blood cells, are a specialized class of blood cells that function to clot blood and stop bleeding. While white blood cells provide immunity, not all of them are active throughout life as some have specific lifespans and functions.
4. Which structure in the respiratory system is responsible for gas exchange?
- A. Trachea
- B. Alveoli
- C. Bronchi
- D. Diaphragm
Correct answer: B
Rationale: The alveoli in the lungs are responsible for gas exchange. Alveoli have a rich blood supply and thin walls, enabling the exchange of oxygen and carbon dioxide. Oxygen diffuses into the blood from the alveoli, while carbon dioxide diffuses out. The trachea functions as an air passage, bronchi are the main airways into the lungs, and the diaphragm is the primary muscle involved in breathing by aiding in lung expansion and contraction, but they are not directly responsible for gas exchange like the alveoli.
5. Complete the following equation: 2 + (2)(2) - 2 รท 2 = ?
- A. 5
- B. 3
- C. 2
- D. 1
Correct answer: A
Rationale: To solve the equation, follow the order of operations (PEMDAS/BODMAS): Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). 1. Calculate inside the parentheses first: (2)(2) = 4. 2. Then, perform multiplication and division: 2 + 4 - 1 = 6 - 1 = 5. Therefore, the correct answer is 5. Choice B (3) is incorrect because multiplication is done before subtraction. Choices C (2) and D (1) are incorrect as they do not follow the correct order of operations to solve the equation.
