Reading

1. What can be inferred about the water management systems in Petra?

Correct answer: C

Rationale: The passage highlights the "elaborate" water systems, suggesting their complexity and importance.

2. In the cardiovascular system, what is the primary function of red blood cells?

Correct answer: A

Rationale: The correct answer is A: 'To transport oxygen throughout the body.' Red blood cells contain hemoglobin, a protein that binds to oxygen in the lungs and carries it to tissues throughout the body. This process is essential for cellular respiration, where oxygen is used to produce energy. Red blood cells do not fight infection (B), regulate blood clotting (C), or remove waste products (D); those functions are carried out by other components of the immune and circulatory systems.

3. In a horizontal chart, the lowest level worker is located at the

Correct answer: B

Rationale: In a horizontal chart, the lowest level worker is typically positioned at the leftmost side, with higher-level workers placed to the right. This arrangement signifies hierarchy, with the top level usually being on the rightmost side. Therefore, the correct answer is B: 'Middle,' as the lowest level worker is situated towards the left of the chart, not the extreme left or right. This positioning helps visually represent the organization's structure and indicates the progression from lower to higher levels as one moves from left to right on the chart.

4. The term "magic number" in nuclear physics refers to specific numbers of protons or neutrons that contribute to:

Correct answer: C

Rationale: The term "magic number" in nuclear physics refers to specific numbers of protons or neutrons that result in exceptional stability of the nucleus. When the number of protons or neutrons in a nucleus align with a magic number, the nucleus is more stable and less likely to undergo spontaneous radioactive decay. This stability is due to the arrangement of nucleons within the nucleus, leading to lower energy states and increased binding energy. Magic numbers play a crucial role in determining the overall stability and behavior of atomic nuclei. Therefore, the correct answer is C: "Exceptional stability of the nucleus."

5. Which of the following can weaken the immune system and increase susceptibility to infections?

Correct answer: C

Rationale: Chronic stress can weaken the immune system by increasing the production of stress hormones like cortisol, which can suppress immune function over time. Prolonged stress can also lead to inflammation, making the body more vulnerable to infections. It is important to manage stress levels through relaxation techniques, exercise, and seeking support to maintain a healthy immune system.

6. What is the tone of the following sentence: "The presentation was informative and engaging."

Correct answer: B

Rationale: The sentence objectively describes the presentation without expressing any specific emotions.
