1. Which sentence uses the pronoun "they" correctly?

• A. Her friends told her they liked her new haircut.
• B. Sarah and I, they went to the movies.
• C. They gave the awards to whomever deserved them.
• D. The birds, they were singing in the trees.

Correct answer: A

Rationale: Option A agrees with the closest noun, "friends."

2. What is the name for the process where a solid changes directly into a gas?

• A. Evaporation
• B. Sublimation
• C. Condensation
• D. Melting

Correct answer: B

Rationale: Sublimation occurs when a solid directly transforms into a gas without passing through a liquid phase.

3. He likewise stresses the need for all the employees to follow orders and instructions from

• A. Scalar chain
• B. Discipline
• C. Unity of command
• D. Order

Correct answer: B

Rationale: The correct answer is B: 'Discipline.' In a business context, discipline refers to the adherence to rules, orders, and instructions to ensure smooth operations and efficiency. The concept of discipline is essential in maintaining order, consistency, and productivity within an organization. It encompasses obeying rules, following instructions, and respecting authority. While the other options like 'Scalar chain,' 'Unity of command,' and 'Order' are important principles in management, they do not directly address the importance of employees adhering to orders and instructions, which is the central focus in this question. Therefore, 'Discipline' is the most suitable answer in this context.

4. Which of the following is NOT a state of matter?

• A. Solid
• B. Liquid
• C. Gas
• D. Superfluid

Correct answer: D

Rationale: While superfluids exhibit some liquid-like properties, they are a distinct state of matter with unique characteristics beyond the traditional solid, liquid, gas, and plasma classifications.

5. Which of the following is the basic unit of the nervous system?

• A. Neuron
• B. Nerve
• C. Ganglion
• D. Neuroglia

Correct answer: A

Rationale: Rationale: Neurons are the basic structural and functional units of the nervous system. They are specialized cells that transmit information through electrical and chemical signals. Nerves are bundles of neurons, ganglia are clusters of nerve cell bodies outside the central nervous system, and neuroglia are support cells for neurons. However, neurons are specifically responsible for transmitting and processing information in the nervous system, making them the basic unit of this system.

6. What type of molecule forms the cell membrane and controls what enters and exits the cell?

• A. Proteins
• B. Carbohydrates
• C. Lipids
• D. Nucleic acids

Correct answer: C

Rationale: The correct answer is C: Lipids. The cell membrane is primarily composed of a double layer of lipids called phospholipids. These phospholipids have a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails, which arrange themselves to form a barrier that controls the passage of substances in and out of the cell. While proteins are also present in the cell membrane and play important roles in transport and cell signaling, lipids are the main structural component responsible for the selective permeability of the membrane. Carbohydrates are typically found on the outer surface of the membrane and are involved in cell recognition and communication. Nucleic acids are not a major component of the cell membrane; they are primarily responsible for storing and transmitting genetic information within the cell.
