Nature's energy efficiency often (i) _______ human technology: despite the intensity of the light fireflies produce, the amount of heat is negligible; only recently have humans developed chemical light-producing systems whose efficiency (ii) _______ the firefly's system.
Kudos for the right answer and explanation
| Blank (i) | Blank (ii) |
|---|---|
| outstrips | stimulates |
| inhibits | rivals |
| determines | reproduce |

The first blank is described by this sentence: "despite the intensity of the light fireflies produce", which means fireflies produce the high intensity of light with very little heat. Hence, they are efficient. The second sentence starts with "only recently...." so that means human technology used to be less efficient than nature. The first blank now very easy to fill and the answer is "outstrips".
The second blank should be something similar to compete because of the logic of the sentence that suggests that only now humans have started to catch up with the fireflies for efficiency. Hence, the correct answer is "rivals".

Stimulate is completely out of scope.
The sense of the sentence is often mather nature is far away more efficient and clever than our science and technology.
Think for instance the spider's web: ceratin web are millions of times more resistant and yet biodegradable of our most resistant and lightweight material such as the kevlar.
This is the sense of outstripping in the first blank.
Therefore, the second part tells us that now we have paired the nature in a certain thing. So, now OUR material rivals with that we do find in nature.
Hope this helps
