Hi I can’t get past lesson08 knowledge test, the question with the drag and drop options for water testing. The options aren’t worded very well ie stir,crush&stir,crush to a paste.I have rewatched the video a number of times and there is no reference to the different ways of crushing/stirring/crushing to a paste re the tablets! Also ‘cap tube’ is misleading as you would do this more than once through the entire process. Help!!
