• List two major obstacles engineers may face when working on this challenge and explain why it may be a barrier.

You may answer these questions in bullets or in paragraph form, as long as all questions are answered in sufficient detail. Please back your answers with scholarly sources, not just your opinion. Please include links to all sources used.
