Reading

1. The author's attitude towards history seems to be

Correct answer: C

Rationale: The passage's overall tone highlights the value and utility of history, showcasing its potential to inspire and guide us, suggesting an optimistic and encouraging view.

2. A group of antibiotics that target the cell wall of bacteria are classified as:

Correct answer: A

Rationale: Rationale: Penicillins are a group of antibiotics that target the cell wall of bacteria by inhibiting the synthesis of peptidoglycan, a key component of the bacterial cell wall. By interfering with cell wall synthesis, penicillins weaken the cell wall, leading to bacterial cell lysis and death. This mechanism of action makes penicillins effective against a wide range of bacteria, particularly Gram-positive bacteria. Tetracyclines (B), Macrolides (C), and Fluoroquinolones (D) have different mechanisms of action and do not specifically target the bacterial cell wall. Tetracyclines inhibit protein synthesis, Macrolides interfere with bacterial ribosomes, and Fluoroquinolones target bacterial DNA gyrase and topoisomerase IV.

3. T cells in the immune system can be categorized into different types. What type of T cell directly kills infected body cells?

Correct answer: B

Rationale: Cytotoxic T cells directly kill infected body cells. These T cells recognize and destroy cells that are infected with viruses or other pathogens. They are crucial for eliminating threats within the body. Helper T cells, on the other hand, assist in coordinating the immune response by activating other immune cells. Regulatory T cells help maintain immune tolerance and prevent autoimmune reactions. Memory T cells are responsible for 'remembering' specific pathogens to mount a faster and stronger immune response upon re-exposure. Therefore, cytotoxic T cells are the correct answer as they directly target and kill infected cells.

4. Centrioles are structures involved in cell division. What is their specific role?

Correct answer: C

Rationale: Centrioles are cylindrical structures found in animal cells that play a crucial role in organizing microtubules during cell division. They form the spindle fibers that help separate chromosomes during mitosis and meiosis. This organization is essential for the proper alignment and separation of chromosomes, ensuring accurate distribution of genetic material to daughter cells. Centrioles do not participate in forming the nuclear envelope, replicating DNA, or protein synthesis. Therefore, the correct answer is C, as centrioles are primarily involved in microtubule organization to facilitate cell division.

5. What is the main function of energy storage technologies in the context of renewable energy?

Correct answer: C

Rationale: Choice C directly addresses the passage's emphasis on managing the fluctuating availability of renewable energy, hence being the main function of storage technologies.

6. Identify the indirect object in the following sentence: "He gave his mother a bouquet of flowers."

Correct answer: A

Rationale: The indirect object tells who or what benefits from the action of the verb.
