1. Which vitamin requires intrinsic factor from the stomach for proper absorption?

A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin B12

Correct answer: D

Rationale: The correct answer is D, Vitamin B12. Vitamin B12 requires intrinsic factor, a glycoprotein produced by the parietal cells in the stomach, for proper absorption in the small intestine. Intrinsic factor binds to B12 and facilitates its absorption in the ileum. Without intrinsic factor, the body cannot effectively absorb Vitamin B12, leading to deficiencies and various health issues. Vitamins A, C, and D do not require intrinsic factor for absorption and have different mechanisms for uptake and utilization within the body.

A. Petra is a modern city built for tourism.
B. Petra's historical significance lies in its architectural achievements.
C. Petra's prosperity was linked to its strategic location on trade routes.
D. Petra's obscurity remains a mystery despite its rediscovery.

Correct answer: C

Rationale: B mentions Petra's architecture, but not its connection to trade. A and D are factually incorrect and not supported by the passage. Choice C accurately identifies Petra's rise and fall as tied to its position on the Silk Road, making it the main idea.

5. Which condition is characterized by inflammation of the inner lining of the stomach?

A. Gastroesophageal reflux disease (GERD)
B. Diverticulitis
C. Ulcerative colitis
D. Gastritis

Correct answer: D

Rationale: The correct answer is D, gastritis. Gastritis refers to the inflammation of the inner lining of the stomach, which can be caused by various factors such as excessive alcohol consumption, prolonged use of NSAIDs, or bacterial infections like H. pylori. Gastroesophageal reflux disease (GERD) is characterized by the backflow of stomach acid into the esophagus, not inflammation of the stomach lining. Diverticulitis is inflammation of small pouches that can develop in the colon, while ulcerative colitis is inflammation in the large intestine. Therefore, gastritis best fits the description of inflammation in the inner lining of the stomach.

6. As a manager, she focuses her energy on both the quality of services rendered to the patients

A. Country club management
B. Organization man management
C. Team management
D. Authority-obedience management

Correct answer: B

Rationale: The correct answer is 'B: Organization man management.' This type of management focuses on maintaining the efficiency and structure of an organization. In this scenario, the manager's emphasis on the quality of services aligns with the principles of organization man management, which prioritizes the coordination of tasks and resources to achieve optimal results within the organization. This contrasts with 'Country club management,' which emphasizes employee satisfaction over task accomplishment; 'Team management,' which focuses on collaboration and teamwork; and 'Authority-obedience management,' which centers on strict hierarchical control. Therefore, the most appropriate choice is 'B: Organization man management.'
