      Question

      Read the passage below and identify which of the

      following statements (1, 2, and 3) can be logically inferred. Select the correct combination from the options provided. Passage: Ocean thermal energy conversion (OTEC) is being explored as a renewable energy source for coastal regions, but its implementation is currently stalled due to the high cost of the specialized deep-sea pipes and the lack of a minimum 20°C temperature difference between the surface and deep water. A research lead at the National Institute of Ocean Technology stated that while OTEC could provide 24/7 baseload power, current atmospheric conditions have caused surface waters to cool slightly, making the thermal gradient insufficient for power generation this season. Government officials have noted that OTEC is a key part of the green energy roadmap, provided the logistical hurdles of offshore installation are met. Statements: 1. OTEC is the only renewable energy source capable of providing 24/7 baseload power for coastal regions. 2. The difference in temperature between surface and deep water is a critical factor in the viability of OTEC. 3. Generating electricity through ocean thermal energy is technically possible.
      A Only 1 Correct Answer Incorrect Answer
      B Only 2 Correct Answer Incorrect Answer
      C Only 2 and 3 Correct Answer Incorrect Answer
      D Only 1 and 3 Correct Answer Incorrect Answer
      E All 1, 2, and 3 Correct Answer Incorrect Answer

      Solution

      Statement 1 is incorrect: While the passage mentions OTEC "could provide 24/7 baseload power," it does not state that it is the only source capable of doing so. Using the word "only" makes the statement an exclusive claim not supported by the text. Statement 2 is correct: The passage explicitly mentions that implementation is stalled because of the "lack of a minimum 20°C temperature difference" and that the current "thermal gradient is insufficient." This confirms that the temperature difference is a requirement that must be taken into consideration. Statement 3 is correct: Similar to the logic in your example, since OTEC is being "explored," is part of a "roadmap," and has specific "requirements for inducing" power, we can infer that the process itself is a scientific possibility, even if current conditions prevent immediate execution.
