Rachel has a glass of juice. She pours her juice into a teacup, and then she pours the juice into a pint glass. She then pours it from the pint glass back into the original glass. She knows the amount of juice has not substantially changed. What does this exemplify

is this an essay or multiple choice

is there a year set? the question is incomplete

dude the first thing it says is that copied answers will get a zero. plus it would take anyone on an incredibly long time to answer. ive seen 2 people asking the exact same question and their questions got taken down. i have the assignment too, and im in the progress of doing it. i suggest going to a more private website, because this is the first place teachers look.

where is the rest of the question. this isn't making sense. can you upload a picture of the question?
