1. The old clock hadn't worked in years, and _____ Ally finally decided to take it off the wall. Which of the following transition words or phrases is most appropriate to complete the sentence?

• A. as a result
• B. conversely
• C. then again
• D. similarly

Correct answer: A

Rationale: The correct answer is 'as a result.' This transition word is most suitable in this context as it indicates a logical consequence. The old clock not working for years led to Ally deciding to take it off the wall. Choices B, C, and D are incorrect. 'Conversely' suggests a contrast, 'then again' implies reconsideration or a contrasting point, and 'similarly' indicates a comparison, none of which align with the cause-and-effect relationship presented in the sentence.

2. Which organ plays a significant role in immune cell production and maturation?

• A. Liver
• B. Kidneys
• C. Bone marrow
• D. Spleen

Correct answer: C

Rationale: The bone marrow is the correct answer. It is the primary site for immune cell production and maturation. The bone marrow is responsible for generating various types of blood cells, including white blood cells crucial for the immune system's function. The liver, kidneys, and spleen have essential functions in the body, such as filtering blood, detoxification, and storage of blood, respectively. However, they are not primarily involved in immune cell production and maturation, making them incorrect choices for this question.

3. What is the primary composition of the stratum corneum, the outermost layer of the epidermis?

• A. Keratinized dead cells
• B. Melanocytes
• C. Langerhans cells
• D. Merkel cells

Correct answer: A

Rationale: The stratum corneum, the outermost layer of the epidermis, is primarily composed of keratinized dead cells. These cells are flattened, fully keratinized, and lack nuclei, serving a protective function for the skin. Melanocytes are responsible for producing melanin, providing skin pigmentation. Langerhans cells are involved in the immune response within the skin. Merkel cells are associated with sensory functions in the skin, particularly in touch sensations. Therefore, the correct answer is A as it accurately reflects the main constituent of the stratum corneum, which acts as a barrier against external factors.

4. A pediatrician notes that an infant's cartilage is disappearing and being replaced by bone. What process has the doctor observed?

• A. Mineralization
• B. Ossification
• C. Osteoporosis
• D. Calcification

Correct answer: B

Rationale: The doctor has observed the process of ossification. Ossification is the natural process where cartilage in the body is replaced by bone. This process takes place during fetal development, growth, and bone fracture healing. Ossification involves the formation of bone tissue by depositing minerals like calcium and phosphorus within the cartilage matrix, leading to the development of a bone structure. Choice A, mineralization, refers to the process of forming mineral deposits in tissues, but it does not involve the replacement of cartilage by bone. Choice C, osteoporosis, is a condition characterized by bone density loss and increased fragility, not the natural process of cartilage replacement by bone. Choice D, calcification, is the process of deposition of calcium salts in various tissues, but it does not specifically involve the replacement of cartilage by bone as in ossification.

5. Based on the information provided within the passage, which of the following can be inferred about King James II's son?

• A. Considering his resemblance to King James II, the young James was likely the legitimate child of the king and the queen.
• B. Given the queen's previous inability to produce a healthy child, there were suspicions about the prince's legitimacy by the English and the Lowland Scots.
• C. James 'the Pretender' was not as popular among the Highland clans as his son Bonnie Prince Charlie.
• D. James was unable to acquire the resources needed to build the army and plan the invasion that his son succeeded in doing.

Correct answer: A

Rationale: The passage describes that the young James bore a strong resemblance to King James II, suggesting that he was likely the legitimate child of the king and the queen. This resemblance supports the inference that the young James was indeed their offspring. Choice B is incorrect because although there were suspicions about the prince's legitimacy, the passage does not mention these suspicions being based on the queen's previous inability to produce a healthy child. Choice C is incorrect as the passage does not compare the popularity of James 'the Pretender' among the Highland clans to his son Bonnie Prince Charlie. Choice D is also incorrect as the passage does not mention James's inability to acquire resources for building an army or planning an invasion.
