1. Which term describes a substance's ability to undergo a change that transforms it into a different substance?

• A. Density
• B. Mass
• C. Reactivity
• D. Volume

Correct answer: C

Rationale: Reactivity refers to a substance's ability to undergo a change that transforms it into a different substance through a chemical reaction. In this context, reactivity specifically refers to the chemical behavior of a substance. Density, mass, and volume are physical properties of a substance and do not describe its ability to undergo a chemical change. Density is the mass per unit volume, mass is the amount of matter in an object, and volume is the amount of space occupied by an object. Therefore, reactivity is the most appropriate term to describe a substance's ability to undergo a transformation into a different substance.

2. Identify the organ responsible for blood filtration.

• A. Liver
• B. Kidneys
• C. Spleen
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys are the organs responsible for blood filtration in the human body. They filter waste products and excess substances from the blood to produce urine. The liver is primarily involved in detoxification and metabolism, the spleen functions in immune responses and blood storage, and the pancreas aids in digestion and blood sugar regulation. Therefore, choices A, C, and D are incorrect as they do not primarily serve the function of blood filtration.

3. Which word is most closely synonymous with the word patronage as it appears in the following statement? . . . that I am sure he will need no charitable aid or condescending patronage

• A. Auspices
• B. Aberration
• C. Acerbic
• D. Adulation

Correct answer: A

Rationale: In the context provided, the word 'patronage' implies supporting or helping someone in a condescending manner. 'Auspices' is the correct answer as it refers to support or sponsorship, especially from an influential or powerful source, without the negative connotations associated with patronage. 'Aberration' (choice B) means a departure from what is normal or expected and is not a synonym for patronage. 'Acerbic' (choice C) means sharp or bitter in tone, which is not related to patronage. 'Adulation' (choice D) means excessive admiration or praise, which is not synonymous with patronage.

4. Parrots, among the most intelligent birds in the world, have been prized pets for many centuries; in fact, the first recorded instance of parrot training was written in the thirteenth century. Which of the following is a synonym for prized as used in the sentence?

• A. unlikely
• B. misunderstood
• C. rewarded
• D. valued

Correct answer: D

Rationale: In the context of the sentence, 'prized' is used to describe how much people value parrots as pets. Synonyms for 'prized' in this context would include esteemed, cherished, or valued, making option D the most suitable choice. Options A, B, and C do not accurately capture the meaning of 'prized' in this sentence.

5. What is the functional group present in amines?

• A. Hydroxyl
• B. Carbonyl
• C. Amine
• D. Nitro

Correct answer: C

Rationale: The functional group present in amines is the amine group, represented as -NH2. Amines are organic compounds characterized by the presence of a nitrogen atom bonded to hydrogen atoms. The amine group distinguishes amines from other types of organic compounds, such as alcohols with the hydroxyl group, ketones with the carbonyl group, and nitro compounds with the nitro group. Therefore, the correct answer is 'C: Amine.'
