1. What is the main function of energy storage technologies in the context of renewable energy?
- A. Reduce the cost of producing solar and wind power.
- B. Enhance the efficiency of energy transmission and distribution.
- C. Compensate for the intermittent nature of renewable energy sources.
- D. Eliminate the need for fossil fuels in electricity generation.
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.
2. The phrase "illuminates not only past events" suggests that history
- A. primarily serves as a nostalgic exercise in remembering old stories.
- B. offers valuable lessons beyond simply recalling occurrences from the past.
- C. is focused solely on factual accuracy and avoids drawing any interpretations.
- D. exists only as a static record of unchanging events with no relevance to our lives.
Correct answer: B
Rationale: The phrase highlights that history goes beyond mere chronology, offering valuable insights and lessons beyond the dates and facts.
3. Which word best completes the sentence: "The scientist conducted the experiment with _____ precision."
- A. extreme
- B. great
- C. utter
- D. remarkable
Correct answer: C
Rationale: Option C emphasizes the absolute and complete accuracy of the experiment.
4. Identify the spectator ions in the reaction: 2KCl + Pb(NO3)2 → 2KNO3 + PbCl2.
- A. K+ and NO3-
- B. K+ and Cl-
- C. Pb2+ and NO3-
- D. Pb2+ and Cl-
Correct answer: B
Rationale: Rationale: - In the reaction, potassium ions (K+) and chloride ions (Cl-) are present on both sides of the equation. They are not involved in the formation of the products and remain unchanged. - Lead ions (Pb2+) and nitrate ions (NO3-) are involved in the formation of the products potassium nitrate (KNO3) and lead(II) chloride (PbCl2). - Therefore, the spectator ions in this reaction are K+ and Cl-.
5. Which sentence uses parentheses correctly?
- A. The suspect was seen driving a red car (a witness reported).
- B. The movie (released in 2022) received critical acclaim.
- C. The restaurant offers a variety of dishes (including vegetarian options).
- D. All participants (must register by Friday) will receive a free gift.
Correct answer: B
Rationale: Parentheses are used for non-essential information that clarifies or adds detail. Option (a) is unnecessary and disrupts the flow of the sentence.
6. Which muscle plays a significant role in the process of forced exhalation by contracting to reduce the thoracic cavity volume?
- A. Diaphragm
- B. External intercostal muscles
- C. Internal intercostal muscles
- D. Abdominal muscles
Correct answer: C
Rationale: The correct answer is C: Internal intercostal muscles. During forced exhalation, these muscles contract to depress the ribs and decrease the thoracic cavity volume, assisting in pushing air out of the lungs. The diaphragm is primarily responsible for inhalation by contracting to increase thoracic cavity volume. External intercostal muscles aid in inhalation by elevating the ribs. Abdominal muscles are involved in activities like coughing, sneezing, and forced exhalation by compressing the abdominal contents to further reduce thoracic volume. Therefore, the internal intercostal muscles have a significant role in forced exhalation.
