When you are brainstorming, what should you be careful to avoid? A. Editing your ideas as you go
B. Setting boundaries for your session
C. Writing down all your ideas D. Setting a time limit for your session

It's most likely B. Setting boundaries for your session

reason: Brainstorming is supposed to be coming up with q bunch of creative ideas. setting to many boundaries may make it harder to come up with new stuff.

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?
