Anatomy

1. What is the function of the pericardium, the sac surrounding the heart?

Correct answer: D

Rationale: The pericardium, the sac surrounding the heart, serves primarily to protect the heart and anchor it in place. It acts as a protective barrier against external infections or damage and helps to maintain the heart's position within the chest cavity. Additionally, the pericardium also provides some degree of shock absorption to minimize physical trauma to the heart. While the heart's electrical impulses for contraction originate from within the heart itself and are not generated by the pericardium, it does not play a role in directly generating these impulses. Therefore, option D, 'To protect the heart and anchor it in place,' is the correct function of the pericardium.

2. The final sentence highlights the need for

Correct answer: C

Rationale: The emphasis on "international cooperation," "robust scientific research," and "adapting" suggests a focus on collaborative and multi-faceted solutions, aligning with C.

3. What is the least common multiple (LCM) of 4 and 6?

Correct answer: B

Rationale: The LCM is the smallest number that is a multiple of both 4 and 6. We can find this by listing out the multiples of each number until we find a common value. In this case, 12 is the first number divisible by both 4 (4 x 3) and 6 (6 x 2).

4. A lampshade consists of a cylindrical base (diameter 20cm, height 10cm) and a hemispherical top (same diameter as the base). What is its total surface area?

Correct answer: D

Rationale: Calculate the surface area of the cylinder (base + lateral surface) and the hemisphere (half of a sphere's surface area). Add both areas to find the total surface area.

5. What is the meaning of the phrase "to be on the same page"?

Correct answer: B

Rationale: The phrase means to be in agreement or share the same understanding.

6. What is the main idea of the passage?

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.
