1. According to the Cahn-Ingold-Prelog (CIP) ranking system, which functional group has the highest priority?

• A. Alcohol (OH)
• B. Aldehyde (CHO)
• C. Carboxylic Acid (COOH)
• D. Amine (NH2)

Correct answer: C

Rationale: In the Cahn-Ingold-Prelog (CIP) ranking system, functional groups are prioritized based on the atomic number of the atoms directly attached to the functional group. Carboxylic acid (COOH) holds the highest priority as the carbon atom is directly bonded to two oxygen atoms, which have higher atomic numbers compared to carbon, hydrogen, or nitrogen. The higher the atomic number of the attached atoms, the higher the priority of the functional group in the CIP ranking system. Therefore, choices A, B, and D are incorrect as they have lower atomic numbers in the atoms directly attached to them, making them lower in priority according to the CIP system.

2. Identify the conjunction in the following sentence:

• A. went
• B. to
• C. but
• D. they

Correct answer: C

Rationale: The correct answer is 'C: but.' Conjunctions are words that connect words, phrases, or clauses. In the sentence 'He went to the store, but they were already closed,' 'but' is a conjunction that joins two contrasting ideas - him going to the store and finding it closed. Choice 'A: went' is a verb, not a conjunction. Choice 'B: to' is a preposition, not a conjunction. Choice 'D: they' is a pronoun, not a conjunction.

3. What is the primary function of antibodies?

• A. Production of white blood cells
• B. Initiation of gluconeogenesis
• C. Promotion of intracellular storage of lipids
• D. Facilitate the breakdown of antigens

Correct answer: D

Rationale: The correct answer is D: Facilitate the breakdown of antigens. Antibodies are protein molecules produced by the immune system in response to the presence of foreign substances, known as antigens, in the body. Antibodies bind to specific antigens and mark them for destruction by other immune cells, thereby helping the body to defend against infections and other threats. Choices A, B, and C are incorrect because antibodies do not have a direct role in the production of white blood cells, initiation of gluconeogenesis, or promotion of intracellular storage of lipids. The primary function of antibodies is to target and facilitate the destruction of antigens in the body.

4. Which of the following sentences uses a comma correctly?

• A. Let's eat Grandma!
• B. Let's eat, Grandma!
• C. Lets eat, Grandma!
• D. Lets, eat Grandma!

Correct answer: B

Rationale: The correct answer is B: 'Let's eat, Grandma!' The comma is correctly used to separate the direct address 'Grandma' from the rest of the sentence. In choice A, there should be a comma after 'eat' to separate the direct address. Choice C is missing an apostrophe in 'Lets,' and there should be a comma after 'eat' to separate the direct address. Choice D incorrectly places a comma after 'Lets,' and there should be a comma after 'eat' to separate the direct address.

5. What property of a wave determines the loudness of sound when heard by the human ear?

• A. Frequency
• B. Amplitude
• C. Wavelength
• D. Velocity

Correct answer: B

Rationale: The amplitude of a wave determines the loudness of sound when heard by the human ear. The greater the amplitude of a sound wave, the louder the sound will be perceived. Frequency (Choice A) refers to the number of wave cycles in a given time period. Wavelength (Choice C) is the distance between two corresponding points on a wave. Velocity (Choice D) is the speed at which the wave travels and does not directly affect the loudness of sound perceived by the human ear.
