      Question

      An argument is given, followed by three statements that

      either strengthen or weaken the given argument. Choose the option that correctly identifies the relationship: 'S' for strengthening and 'W' for weakening. Argument: A leading automobile manufacturer plans to transition its entire production line to solid-state batteries (SSBs) by 2030 to increase the range and safety of its electric vehicles. Statements: I. Recent laboratory breakthroughs have demonstrated that solid-state batteries can provide twice the energy density of current lithium-ion batteries while being significantly less prone to fire. II. Industry reports suggest that the rare-earth minerals required for solid-state electrolytes are currently subject to extreme supply chain volatility and high extraction costs. III. A survey of current electric vehicle owners indicates that "range anxiety" remains the single largest deterrent for consumers considering a long-term switch from internal combustion engines.
      A SWS Correct Answer Incorrect Answer
      B SSW Correct Answer Incorrect Answer
      C SWW Correct Answer Incorrect Answer
      D WSW Correct Answer Incorrect Answer
      E WWW Correct Answer Incorrect Answer

      Solution

      Statement I is 'S' (Strengthening): It validates the technical claims of the manufacturer by confirming that SSBs fulfill the goals of increased range (energy density) and safety (less fire-prone). Statement II is 'W' (Weakening): It raises a practical and economic barrier. High costs and supply chain volatility suggest that transitioning the "entire production line" might be financially unfeasible or risky by 2030. Statement III is 'S' (Strengthening): It strengthens the rationale behind the plan. By showing that the market's biggest concern is exactly what the new technology addresses (range), it supports the strategic necessity of the move.
