1. Aseptic meningitis is an inflammation of the meninges caused by:
- A. Bacteria
- B. Viruses
- C. Fungi
- D. Parasites
Correct answer: B
Rationale: Rationale: Aseptic meningitis is typically caused by viral infections, such as enteroviruses (e.g., coxsackievirus, echovirus), herpes simplex virus, varicella-zoster virus, and others. These viruses can infect the meninges, leading to inflammation and symptoms of meningitis without the presence of bacteria. While bacterial meningitis is a serious and life-threatening condition, aseptic meningitis caused by viruses is usually less severe and has a better prognosis. Fungi and parasites are less common causes of meningitis compared to bacteria and viruses.
2. What is the largest part of the brain and is responsible for higher functions like thinking, memory, and learning?
- A. Brainstem
- B. Cerebellum
- C. Cerebrum
- D. Thalamus
Correct answer: C
Rationale: The correct answer is C: Cerebrum. The cerebrum is the largest part of the brain and is responsible for higher functions like thinking, memory, and learning. It is divided into two hemispheres (left and right) and is associated with intelligence, creativity, reasoning, and problem-solving abilities. The brainstem (option A) is responsible for basic life functions like breathing and heart rate. The cerebellum (option B) is involved in coordination and balance. The thalamus (option D) acts as a relay station for sensory information. Therefore, the cerebrum is the most appropriate choice for the part of the brain responsible for higher cognitive functions.
3. What is the main function of the epiglottis, a small flap of cartilage located above the larynx?
- A. To warm and humidify inhaled air
- B. To control the passage of food and air
- C. To produce sound vibrations for speech
- D. To sense the presence of foreign objects
Correct answer: B
Rationale: The correct answer is B: 'To control the passage of food and air.' The epiglottis is a crucial structure that prevents food and liquids from entering the airway during swallowing. It acts as a lid over the trachea, ensuring that food goes down the esophagus while air passes into the respiratory system. This function is essential for preventing choking and ensuring proper breathing. Options A, C, and D are incorrect as the epiglottis is not primarily responsible for warming and humidifying inhaled air, producing sound vibrations for speech, or sensing foreign objects.
4. Which term describes the functional unit of a skeletal muscle responsible for muscle contraction?
- A. Myofibril
- B. Sarcomere
- C. Tendon
- D. Myoglobin
Correct answer: b
Rationale: The correct answer is B: Sarcomere. A sarcomere is the functional unit of a skeletal muscle responsible for muscle contraction. It is made up of overlapping filaments of actin and myosin proteins. Myofibrils are long, cylindrical structures within muscle cells that contain sarcomeres. Tendons are tough bands of fibrous connective tissue that connect muscles to bones and facilitate movement. Myoglobin is a protein found in muscle cells that stores oxygen for muscle use during exercise. Therefore, the sarcomere is specifically responsible for muscle contraction, making it the correct answer in this question.
5. Based on the passage, the author's stance on AI is likely to be
- A. Unconditionally enthusiastic, embracing all forms of AI development without reservations.
- B. Cautiously optimistic, acknowledging both the potential and risks while advocating for responsible use.
- C. Strongly critical, focusing solely on the potential dangers of AI and advocating for its complete halt.
- D. Apathetic and indifferent, lacking any strong opinion on the impact or future of AI.
Correct answer: B
Rationale: The emphasis on balancing benefits and risks suggests a cautious and balanced perspective, aligning with B.
6. She plans of assigning competent people to fill the roles designed in the hierarchy. Which
- A. Staffing
- B. Scheduling
- C. Recruitment
- D. Induction
Correct answer: B
Rationale: The correct answer is B: Scheduling. Scheduling involves assigning people to specific tasks or roles within an organization based on the hierarchy and operational needs. In this scenario, the focus is on assigning competent individuals to fill the roles outlined in the hierarchy, which aligns with the concept of scheduling. Staffing refers to the overall process of acquiring, deploying, and retaining a workforce; recruitment specifically pertains to attracting and selecting candidates for job roles; and induction involves the orientation and integration of new employees into the organization. Therefore, the most relevant term in this context is scheduling.
