1. What is Diffusion?

• A. Movement of materials from low concentration to high concentration
• B. Movement of materials from high concentration to low concentration
• C. Absorption of nutrients
• D. Breaking of materials

Correct answer: B

Rationale: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Choice A is incorrect because diffusion occurs down the concentration gradient, from high to low concentration, not from low to high concentration. Choice C is incorrect as it refers to the uptake of substances by cells, not the general process of diffusion. Choice D is incorrect as it does not accurately describe the process of diffusion; diffusion involves the movement of substances, not the breaking of materials.

2. What does alimentary mean?

• A. Related to nourishment
• B. Related to outflow
• C. Related to simplicity
• D. Related to protection

Correct answer: A

Rationale: The term 'alimentary' is used to describe things that are related to nourishment or the process of providing food or nourishment. It is often associated with the digestive system and the intake of food. Therefore, the correct answer is A: Related to nourishment. Choice B, 'Related to outflow,' is incorrect because alimentary is not associated with outflow but rather with intake. Choice C, 'Related to simplicity,' and choice D, 'Related to protection,' are unrelated to the meaning of alimentary.

3. 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.

4. The meteorologist had forecast rain, ____________ Sheila brought her umbrella to work.

• A. Nor
• B. Yet
• C. Because
• D. So

Correct answer: C

Rationale: The sentence implies a cause-and-effect relationship, so 'because' is the appropriate conjunction. 'Nor' is used in negative constructions, 'Yet' indicates contrast, and 'So' is used to show a consequence, none of which fit the context of the sentence.

5. What is the best description for the abbreviation EEG?

• A. A test of brain activity
• B. A medical service
• C. A heartbeat monitor
• D. A specialist in dentistry

Correct answer: A

Rationale: The correct answer is A: 'A test of brain activity.' EEG stands for Electroencephalogram, a test used to evaluate the electrical activity in the brain. It helps diagnose conditions like epilepsy, seizures, and other brain disorders. Choice B, 'A medical service,' is too broad and does not specifically refer to EEG. Choice C, 'A heartbeat monitor,' is incorrect as EEG does not monitor the heart. Choice D, 'A specialist in dentistry,' is unrelated to the abbreviation EEG.
