Read the quotation from henry david thoreau’s walden. once it chanced that i stood in the very abutment of a rainbow’s arch, which filled the lower stratum of the atmosphere, tinging the grass and leaves around, and dazzling me as if i looked through colored crystal. it was a lake of rainbow light, in which, for a short while, i lived like a dolphin. if it had lasted longer it might have tinged my employments and life. which is the best example of a vivid sensory detail? 1.“once it chanced that i stood” 2.“if it had lasted longer” 3.“which, for a short while” 4.“it was a lake of rainbow light”
