Fill in the blanks:
Though their design was ___________ in the 1950s for newer technological developments, Stanford scientists are ___________ it today as a way to bring refrigeration to areas without electricity.

"Abandoned" means left unused or given up, which makes sense as the design was discarded in the past."Revisiting" means looking at something again, which fits the context of scientists reconsidering the old design for modern use.Neglected, discarding – If something is being discarded today, it wouldn't be used for refrigeration.Outdated, rejecting – "Rejecting" does not fit because the scientists are actually reconsidering the design.Dismissed, overlooking – "Overlooking" means ignoring, which contradicts the idea of reusing the design.Option 1, completes the sentence in all the aspects making it the correct answer.
