Instruction: Identify the assumptions that must hold for the statement to be valid, then choose the correct option.
Statement: While technological advancements in energy production have made renewable sources more cost-competitive, their intermittent nature means that large-scale adoption will require significant investments in energy storage technologies to stabilize the grid.
Assumptions:
I. Renewable energy sources are not continuous and need energy storage solutions.
II. The high cost of renewable energy production makes its adoption difficult without subsidies.
III. Energy storage technologies are a necessary component of a stable energy grid with high renewable energy input.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Only I and III are implicit.
Assumptions:
I. Implicit (this is the main reason mentioned - intermittent nature).
II. Not implicit (because statement says renewables are becoming cost-competitive, so cost is not the issue.
III. Implicit (because it is directly stated (to stabilize the grid)).
