Final answer:
The word 'light' in the given text has two meanings: as actual illumination from a flashlight in the first instance, and metaphorically as the spark of an idea in Richard's mind in the second instance.
Step-by-step explanation:
In the context of the seventh paragraph from 'A Kenyan Teen's Discovery Let There Be Lights to Save Lions' by Nina Gregory, the word light is used in two different ways. In the first sentence, the word light refers to the illumination that makes things visible, specifically the flashlight Richard was using to scare lions away from livestock. In contrast, the second sentence uses the word light metaphorically to describe the beginnings of an idea that sparked in Richard's mind after he noticed the effect of the moving flashlight on lions.
