Read the following passage and answer the question below. As the world shifts toward renewable energy sources such as solar and wind power, the development of efficient energy storage technology has become increasingly critical. Because renewable sources are intermittent, generating electricity only when the sun shines or the wind blows, batteries are needed to store excess energy for use during periods of low generation. Lithium-ion batteries, widely used in everything from smartphones to electric vehicles, have become the dominant storage technology due to their high energy density and relatively long lifespan. However, researchers are actively exploring alternative battery chemistries, such as solid-state and sodium-ion batteries, which promise improved safety, lower costs, and reduced reliance on scarce materials like cobalt and lithium. Large-scale battery storage facilities are also being built alongside power grids to help balance supply and demand, reducing the need for fossil-fuel-based backup power plants. Continued advances in battery technology are widely seen as essential to achieving a fully renewable and reliable electricity grid. Question: What is the passage primarily about?
Difficulty: Medium
About this MCQ
This Medium Reading Comprehension question asks: Read the following passage and answer the question below. As the world shifts toward renewable energy sources such as solar and wind power, the development of efficient energy storage technology has become increasingly critical. Because renewable sources are intermittent, generating electricity only when the sun shines or the wind blows, batteries are needed to store excess energy for use during periods of low generation. Lithium-ion batteries, widely used in everything from smartphones to electric vehicles, have become the dominant storage technology due to their high energy density and relatively long lifespan.

Large-scale battery storage facilities are also being built alongside power grids to help balance supply and demand, reducing the need for fossil-fuel-based backup power plants. Continued advances in battery technology are widely seen as essential to achieving a fully renewable and reliable electricity grid. Question: What is the passage primarily about? The correct choice is C. The role of battery technology in supporting the shift to renewable energy. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Reading Comprehension items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Reading Comprehension so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Reading Comprehension item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. The chemistry of lithium extraction
Why not A: “The chemistry of lithium extraction” does not fit this question. The answer is The role of battery technology in supporting the shift to renewable energy.
- B. The design of solar panels
Why not B: “The design of solar panels” does not fit this question. The answer is The role of battery technology in supporting the shift to renewable energy.
- C. The role of battery technology in supporting the shift to renewable energy ✓
- D. The history of the electric vehicle
Why not D: “The history of the electric vehicle” does not fit this question. The answer is The role of battery technology in supporting the shift to renewable energy.
