The best fit definition for this example would be definition 3. Definition 2 doesn't apply to closing a window correctly so that is already out of the question. A bolt that is part of a window isn't made out of fabric so definition 4 is out as well. Now that it's down to 1 and 3, considering it says "please make sure you latch the bolt", keep in mind that the definition of 'latch' is "a metal bar with a catch and lever used for fastening a door or gate" so choice number 3 would best fit :) Hope this helps! x
