1. What is the most visible part of the ear?

• A. Pinna
• B. Organ of Corti
• C. Cochlea
• D. Ear canal

Correct answer: A

Rationale: The pinna, also known as the auricle, is the external part of the ear that is most visible. It helps in collecting sound waves and directing them into the ear canal for further processing by the ear structures. The pinna's visible location makes it easily identifiable as the prominent external feature of the ear. Choices B, C, and D are incorrect. The Organ of Corti is located within the cochlea and is responsible for converting sound vibrations into electrical signals. The cochlea is a spiral-shaped, fluid-filled structure in the inner ear that plays a crucial role in hearing. The ear canal is a passage that leads to the eardrum and is not the most visible part of the ear.

2. Select the meaning of the word 'distended' in the sentence: 'Wracked by abdominal pain, the victim of food poisoning moaned and rubbed his distended belly.'

• A. concave
• B. sore
• C. swollen
• D. empty

Correct answer: C

Rationale: The correct answer is C: 'swollen.' In the context provided, 'distended' refers to the victim's belly being enlarged or bloated due to abdominal pain. This matches the description of the victim moaning and rubbing his belly, indicating discomfort from swelling. Choices A, B, and D are incorrect. 'Concave' means having an inward curve, opposite to the intended meaning. 'Sore' means experiencing pain or discomfort, which is not directly related to the physical enlargement described in the sentence. 'Empty' means containing nothing, which contrasts with the idea of the belly being visibly enlarged or bloated.

3. Which organelle is the site of photosynthesis in plant cells?

• A. Mitochondria
• B. Chloroplasts
• C. Ribosomes
• D. Endoplasmic Reticulum

Correct answer: B

Rationale: The correct answer is B: Chloroplasts. Chloroplasts are responsible for conducting photosynthesis in plant cells. They contain chlorophyll, a pigment that captures light energy and converts it into chemical energy through the process of photosynthesis. Mitochondria (choice A) are known as the powerhouse of the cell and are involved in cellular respiration, not photosynthesis. Ribosomes (choice C) are responsible for protein synthesis. The endoplasmic reticulum (choice D) is involved in protein and lipid synthesis and transport within the cell, not photosynthesis.

4. LABILE also means .

• A. Extremely changing
• B. Suicidal
• C. Rapidly changing
• D. With a high fever

Correct answer: A

Rationale: The word 'labile' is used to describe something that is constantly changing or easily altered. Therefore, the best synonym for 'labile' is 'extremely changing.' Choice B, 'suicidal,' is incorrect as it does not relate to the meaning of 'labile.' Choice C, 'rapidly changing,' is close but not as precise as 'extremely changing.' Choice D, 'with a high fever,' is completely unrelated to the meaning of 'labile.'

5. Choose the word or phrase that best indicates the meaning of the 'quoted' word. 'Rational' means:

• A. Angry
• B. Reason
• C. Rodent
• D. Proportion

Correct answer: B

Rationale: The correct answer is 'B: Reason.' 'Rational' means based on reason or logic. Choice A, 'Angry,' is incorrect as it does not relate to the meaning of 'rational.' Choice C, 'Rodent,' is a completely unrelated term. Choice D, 'Proportion,' also does not capture the meaning of 'rational,' which is about being logical or reasonable.
