The lecture will extend its coverage beyond established renewable technologies to concentrate on _________________ fields.
✅ Why correct: The passage explicitly states the lecture will "explore nascent fields like advanced geothermal, bioenergy 2.0, and ocean energy." The word "nascent" directly aligns with the idea of moving beyond established technologies to focus on new, emerging areas. ❌ Why wrong: * **Experimental:** While nascent fields might involve experimentation, the passage uses the more precise term "nascent" to describe their early stage of development, not just their experimental nature. * **Declining:** The passage clearly focuses on new and advancing technologies, making "declining" a direct opposite and incorrect option. * **Alternative:** While these fields are alternatives to traditional energy, "nascent" specifically highlights their emerging and developing status, which is a more precise fit for the context of moving "beyond established renewable technologies." ⚠️ Trap pattern: Distractor based on partial truth/related concept. "Experimental" and "alternative" are somewhat related to nascent fields, but they don't capture the exact emphasis of the passage on the *emerging* nature of these technologies. 💡 Next step: When encountering sentence completion tasks, pay close attention to adjectives and adverbs. They often provide crucial clues about the specific nuance required to complete the sentence accurately. Also, reread the surrounding sentences in the passage to ensure your chosen word fits the broader context.
