1. Select the meaning of the word 'trepidation' in the sentence: 'The students approached the cadaver with some trepidation.'

• A. Wonder
• B. Confusion
• C. Eagerness
• D. Apprehension

Correct answer: D

Rationale: In this sentence, the word 'trepidation' is used to describe the feeling the students had when approaching the cadaver. Trepidation means a feeling of fear or anxiety about something that may happen, so it aligns most closely with the meaning of 'apprehension.' The students were hesitant or worried about facing the cadaver. Choice A ('Wonder') is incorrect as trepidation does not signify a feeling of wonder. Choice B ('Confusion') is incorrect as trepidation is not about being confused. Choice C ('Eagerness') is incorrect as trepidation is the opposite of eagerness; it indicates hesitation or anxiety, not excitement or enthusiasm.

2. To be convoluted is to be _______.

• A. Complex
• B. Clever
• C. Candid
• D. Asinine

Correct answer: A

Rationale: The correct answer is A, 'Complex.' The term 'convoluted' is used to describe something that is intricate, complex, or twisted. 'Clever' (choice B) means showing intelligence or skill, 'Candid' (choice C) means truthful and straightforward, and 'Asinine' (choice D) means extremely foolish or silly. These choices do not accurately reflect the meaning of 'convoluted.'

3. A car, starting from rest, accelerates at 10 m/s² for 5 seconds. What is the velocity of the car after 5 seconds?

• A. 2 m/s
• B. 5 m/s
• C. 50 m/s
• D. The answer cannot be determined from the information given.

Correct answer: C

Rationale: The velocity of an object can be calculated using the formula: final velocity = initial velocity + (acceleration × time). In this case, the car starts from rest, so the initial velocity is 0 m/s. Given that the acceleration is 10 m/s² and the time is 5 seconds, we can plug these values into the formula to find the final velocity: final velocity = 0 m/s + (10 m/s² × 5 s) = 0 m/s + 50 m/s = 50 m/s. Therefore, the velocity of the car after 5 seconds is 50 m/s. Choice A (2 m/s) and Choice B (5 m/s) are incorrect because they do not consider the acceleration the car undergoes over the 5 seconds, resulting in a final velocity greater than both. Choice D (The answer cannot be determined from the information given) is incorrect as the final velocity can be determined using the provided data and the kinematic equation.

4. Which substance causes a drop to rapidly turn litmus dye from blue to red?

• A. Milk
• B. Sea water
• C. Ammonia
• D. Lemon juice

Correct answer: D

Rationale: Lemon juice is the correct answer as it is acidic in nature. Acids like lemon juice release hydrogen ions when dissolved in water, which causes litmus dye to change color from blue to red. Milk (Choice A) is neutral, sea water (Choice B) is slightly alkaline, and ammonia (Choice C) is a base. Therefore, these substances do not cause litmus dye to change from blue to red.

5. You have been given a sample tissue that has pillar-shaped cells arranged tightly together. The tissue you have is:

• A. Squamous Epithelium
• B. Cuboidal Epithelium
• C. Columnar Epithelium
• D. Transitional Epithelium

Correct answer: C

Rationale: The correct answer is C: Columnar Epithelium. Columnar epithelium is characterized by tall, pillar-like cells that are closely packed together. This arrangement allows for absorption and secretion in tissues like the digestive tract, where this type of epithelium is commonly found. Squamous epithelium (choice A) consists of flat cells, cuboidal epithelium (choice B) has cube-shaped cells, and transitional epithelium (choice D) is found in areas that need to stretch and expand, like the urinary bladder.
