origins of ambiguityunclear problems
identify the best locations to plant new treeshow many?
what kinds of trees? move old trees?
replace old trees?
aesthetically pleasing? maximize growth? increase foliage? offset CO2 emissions?

Lorem Ipsum: a narrative about blankets.
Author: Charlie Brown
Date: 31 Jan 2012 !Lorem Ipsum is a dummy text used when typesetting or marking up documents. It has a long history starting from the 1500s and is still used in digital millennium for typesetting electronic documents, page designs, etc. !In itself, the original text of Lorem Ipsum might have been taken from an ancient Latin book that was written about 50 BC. Nevertheless, Lorem Ipsum’s words have been changed so they don’t read as a proper text. !Naturally, page designs that are made for text documents must contain some text rather than placeholder dots or something else. However, should they contain proper English words and sentences almost every reader will deliberately try to interpret it eventually, missing the design itself. !However, a placeholder text must have a natural distribution of letters and punctuation or otherwise the markup will look strange and unnatural. That’s what Lorem Ipsum helps to achieve. !I would like to thank Peppermint Patty for her support on studying
Lorem Ipsum as well as the infinite wisdom of Linus van Pelt and his willingness to use his blanket in my experiments.
