1. The phrase "robust ethical frameworks" refers to

• A. Complex algorithms and mathematical models used in AI development.
• B. Comprehensive sets of guidelines and regulations governing AI development and deployment.
• C. Advanced hardware and software systems necessary for building powerful AI systems.
• D. Public education campaigns raising awareness about the potential benefits and risks of AI.

Correct answer: B

Rationale: Ethical frameworks are sets of principles and guidelines that ensure responsible AI development and address potential risks, aligning with B.

2. The element responsible for the red color of blood is:

• A. Magnesium
• B. Iron
• C. Copper
• D. Zinc

Correct answer: B

Rationale: Hemoglobin, the protein responsible for carrying oxygen in red blood cells, contains iron in its heme group, contributing to the blood's characteristic red color.

3. The T wave on an ECG corresponds to:

• A. Atrial depolarization
• B. Ventricular depolarization
• C. Atrial repolarization
• D. Ventricular repolarization

Correct answer: D

Rationale: The T wave on an ECG corresponds to ventricular repolarization. During this phase, the ventricles are resetting electrically after contraction, preparing for the next heartbeat. Atrial depolarization is represented by the P wave, ventricular depolarization by the QRS complex, and atrial repolarization is typically hidden within the QRS complex. Therefore, option D, 'Ventricular repolarization,' is the correct choice when identifying the electrical activity represented by the T wave on an ECG.

4. What literary device is used in the line "The sea whispered secrets to the shore"?

• A. Alliteration
• B. Personification
• C. Onomatopoeia
• D. Hyperbole

Correct answer: B

Rationale: The sentence gives human qualities to the sea, like whispering, creating personification.

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. In meiosis I, how are sister chromatids distinguished from homologous chromosomes?

• A. Sister chromatids share the same centromere, while homologues have different centromeres.
• B. Sister chromatids have identical DNA sequences, while homologues have slightly different sequences due to crossing over.
• C. Sister chromatids repel each other, while homologues attract each other during synapsis.
• D. Sister chromatids separate during anaphase I, while homologues separate during anaphase II.

Correct answer: B

Rationale: While sister chromatids are identical copies of the same chromosome, homologous chromosomes are paired copies, each inherited from one parent. Crossing over during meiosis I can lead to slight differences in their DNA sequences.
