1. After discussing the possible effects of the low patient satisfaction rate, the staff started to list

• A. Collaboration
• B. Majority rule
• C. Dominance
• D. Compromise

Correct answer: B

Rationale: The correct answer is B: 'Majority rule.' In this scenario, the staff is likely listing potential solutions or actions based on the opinion or agreement of the majority. Collaboration (A) involves working together towards a common goal, while Dominance (C) implies one person or group having control. Compromise (D) suggests finding a middle ground between different viewpoints. Majority rule best fits the situation where a decision or list of actions is being determined by what most people agree on, which is a common approach in group decision-making processes.

2. Which number is the opposite of -3?

• A. -6
• B. 3
• C. 0
• D. 6

Correct answer: B

Rationale: The opposite of a number is the one with the same distance from zero but on the opposite side of the number line. So, the opposite of -3 is 3.

3. What is the function of ribosomal RNA (rRNA)?

• A. Carries amino acids to the ribosomes
• B. Reads th(a) Carries amino acids to the ribosomes: This is the function of transfer RNA (tRNA), not ribosomal RNA. (b) Reads the genetic code on mRNA: This is the function of the ribosomes as a whole, not just the ribosomal RNA. (d) Controls the rate of protein synthesis: This is a more complex process involving various factors, not solely ribosomal RNA. e genetic code on mRNA
• C. Forms the structural framework of ribosomes
• D. Controls the rate of protein synthesis

Correct answer: C

Rationale: Rationale: Ribosomal RNA (rRNA) plays a crucial role in forming the structural framework of ribosomes, which are the cellular organelles responsible for protein synthesis. Ribosomes consist of both protein and rRNA components, with rRNA providing the structural support necessary for the ribosome to function properly. This structural framework allows the ribosome to interact with messenger RNA (mRNA) and transfer RNA (tRNA) during the process of translation, where the genetic information encoded in mRNA is used to assemble proteins from amino acids. Therefore, the primary function of rRNA is to contribute to the structure and function of ribosomes, rather than directly carrying amino acids, reading the genetic code, or controlling the rate of protein synthesis.

4. Elements tend to gain or lose electrons to achieve stable electron configurations like those of noble gases. Their group number often indicates the number of electrons gained/lost and the resulting ionic charge, providing a good starting point for prediction.

• A. Ionic bonds involve electron sharing, while metallic bonds involve electron transfer
• B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional
• C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals
• D. Ionic bonds form discrete molecules, while metallic bonds form extended structures

Correct answer: D

Rationale: Ionic bonds involve complete electron transfer between atoms, creating strong, non-directional electrostatic attraction. Metallic bonds involve a delocalized "sea" of electrons shared across all metal atoms, resulting in a strong, extended structure.

5. Identify the appositive in the following sentence: "My favorite author, Agatha Christie, wrote many detective novels."

• A. favorite
• B. Agatha Christie
• C. many
• D. novels

Correct answer: B

Rationale: An appositive renames or clarifies the noun or pronoun preceding it.

6. Which of the following is responsible for generating the electrical impulses that regulate the heartbeat?

• A. Aorta
• B. Pulmonary veins
• C. Coronary arteries
• D. Sinoatrial (SA) node

Correct answer: D

Rationale: The correct answer is D: Sinoatrial (SA) node. The SA node, also known as the heart's natural pacemaker, is responsible for generating the electrical impulses that regulate the heartbeat. These impulses initiate each heartbeat by causing the atria to contract. The other options, Aorta, Pulmonary veins, and Coronary arteries, are important structures in the cardiovascular system but are not directly responsible for generating the electrical impulses that regulate the heartbeat.
