Question

Instruction: Identify the assumptions that must hold for the statement to be valid, then choose the correction option. Statement: While technological advancements in energy production have made renewable sources more costcompetition, their intermittent nature means that largescale adoption will require significant investments in energy storage technologies to stabilise the grid. Assumptions:

I. Renewable energy sources are not continuous and need energy storage solution.

II. The high cost of renewable energy production makes its adoption difficult without subsidies.

III. Eneregy storage technologies are a necessary component of a stable energy grid with high renewable energy input.

1. A. Only I and III are implicit (Correct answer)
2. B. Only II and III are implicit
3. C. Only I is implicit
4. D. All assumptions are implicit

Correct Answer

Option A — Only I and III are implicit

Detailed Solution & Explanation

The correct answer is Only I and III are implicit.

Key Points

• The argument says renewable energy's intermittent nature means large-scale adoption needs investment in storage to stabilise the grid.
• This silently assumes (I) that renewables are not continuous and need storage — that is what 'intermittent' commits to — and (III) that storage technologies are necessary for a stable, renewables-heavy grid, which is the very link the recommendation stands on.
• Assumption II (about production cost and subsidies) introduces economics the statement never touches; an argument can't be assuming something it doesn't need.
• An assumption is implicit only if denying it breaks the argument.
