Superconductors are materials that can conduct electricity with zero resistance, leading to unprecedented energy efficiency and technological advancements. In summary, LK-99 represents an exciting prospect as a potential room-temperature superconductor, but its superconducting properties have yet to be confirmed and independently verified.
Room temperature superconductors could revolutionize the energy sector by enabling lossless power transmission over long distances. With reduced energy dissipation during transmission, electricity could be distributed more efficiently, lowering carbon footprints and electricity costs.

Gabarito
Errado
Comentário do professor
Comentário: A afirmação está ERRADA porque o adjetivo “groundbreaking” significa algo inovador ou revolucionário, enquanto “conventional” se refere a algo tradicional ou comum. Substituir “groundbreaking” por “conventional” mudaria significativamente o sentido da frase, pois o texto destaca a importância e a novidade do LK-99 como supercondutor potencial, ao passo que “conventional” sugeriria que se trata de algo já estabelecido e familiar, o que não se aplica ao contexto apresentado.
