Atechnician removes the cap from the brake fluid reservoir and finds that the rubber boot in the cap is swollen. technician a says this is because there is water in the brake fluid. technician b says this is because the brake fluid level is too low. which technician is correct?

Technician A is correct, there could be water or other contaminant in the brake fluid reservoir. The swollen cap needs to be replaced, some sell only the rubber part of the cap which could help save you money.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
