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. Select the meaning of the word 'exogenous' in the sentence: 'Exogenous factors will affect the patient’s well-being.'

• A. Produced outside the body
• B. Produced within the body
• C. Produced by the kidneys
• D. Hereditary

Correct answer: A

Rationale: The correct answer is A: 'Produced outside the body.' In the given sentence, 'exogenous' is used to refer to factors that originate externally, such as environmental influences. Choice B, 'Produced within the body,' is incorrect as it describes endogenous factors. Choice C, 'Produced by the kidneys,' is incorrect as it specifies a specific organ rather than the general concept of external origin. Choice D, 'Hereditary,' is incorrect as it relates to genetic inheritance, which is not the meaning of 'exogenous.'

3. Which phrase should be moved to the end of the sentence? 'The painter decided to use the urn as his subject with flowers on the table.'

• A. as his subject
• B. with flowers on the table
• C. use the urn as his subject
• D. with the urn

Correct answer: B

Rationale: Moving 'with flowers on the table' to the end of the sentence improves the sentence flow and clarity. This placement helps to maintain a logical sequence of events, enhancing the reader's understanding. Choice A, 'as his subject,' is an integral part of the main action and should not be moved. Choice C, 'use the urn as his subject,' disrupts the verb-object relationship and makes the sentence less coherent. Choice D, 'with the urn,' lacks context and does not provide a smooth transition when placed at the end of the sentence.

4. Which phrase best completes the sentence: 'Despite _____, he managed to complete the race.'

• A. his injury
• B. his condition
• C. his pain
• D. his fatigue

Correct answer: A

Rationale: The correct answer is 'A: his injury.' In the context of completing a race, an injury would be a significant obstacle to overcome. While choices B, C, and D could also pose challenges, an injury is the most severe hindrance that would make completing a race particularly difficult. His condition, pain, or fatigue may affect performance, but they are not as directly impactful as an injury in this scenario.

5. Which word names an infected swelling with liquid inside?

• A. Blast
• B. Gash
• C. Hive
• D. Boil

Correct answer: D

Rationale: A boil is an infected swelling on the skin filled with pus, which is a type of liquid. It is typically caused by a bacterial infection in a hair follicle or oil gland. The other options, blast, gash, and hive, do not specifically describe an infected swelling with liquid inside like a boil does. A 'blast' is a sudden strong movement or gust, 'gash' refers to a long, deep cut or wound, and 'hive' is a skin reaction characterized by itchy welts.
