NO, IT CANT BE DONE

IF U PULL ONE ITEM FROM ONLY ONE BOX AND ANY BOX. THEN ALL BOXES CAN HAVE BOTH ITEMS OR, IF THAT DIDNT MAKE SENSE...

PULL FROM A BOX IF IT IS A SCREW THEN THE ONLY THING U KNOW IS THAT, THAT BOX DID INDEED INCLUDE A SCREW, BUT THIS DOES NOT CONCLUDE THAT U DONT HAVE NAILS IN IT...THIS IS THE ONLY THING YOU CAN DEDUCE FROM PULLING ANY ONE OBJECT FROM ANY ONE BOX. SO U WILL ALWAYS GET AN ANSWER ON AN OBJECT THAT CAN INDEED BE INCLUDED IN THE BOX BUT THERE IS NO WAY TO BE SURE THAT THE BOX DOESNT INCLUDE THE OTHER TYPE OF ITEM OR NOT. SO YOU WILL NOT KNOW WHAT LABEL TO PUT ON THE BOX. IN THE DIAGRAM THE PART THAT SAYS [bOX 1], [bOX 2] AND SO ON IS JUST FOR LABELING PURPOSES TO BETTER DESCRIBE THE PUZZLE, IT DOESNT MEAN U KNOW BEFOREHAND WHICH BOX IS 1, 2, OR 3 NOR DO U KNOW WHICH BOX IS NAILS, SCREWS, OR NAILS AND SCREWS, ALL U KNOW IS THAT ALL THE LABELS ARE WRONG.

This should be easy since ALL boxes are labeled incorrectly.

Start from box 3. This can only be labeled as nails or as screws since it is incorrectly labeled. Whatever you picked up from here is the correct label.

SITUATION 1:

If you picked up a screw on the 3rd box, label this as “SCREWS”.

With box 3 confirmed as screw, you can move to box 1. Since we have eliminated screws on the option, box 1 can only be nails or nails and screw. However, it is incorrectly labeled so you cannot label it as nails, you can then conclude that box 1 should be labeled as “NAILS AND SCREWS”. The remaining label is “NAILS” so you can then conclude that this belongs to box 2.

SITUATION 2:

If you picked up a nail on the 3rd box, label this as “NAILS”.

With box 3 confirmed as nails, you can move to box 2. Since we have eliminated nails on the option, box 2 can only be screws or nails and screws. However, it is incorrectly labeled so you cannot lable it as screws, you can then conclude that box 2 should be labeled as “NAILS and SCREWS”. The remaining label is “SCREWS” so you can then conclude that this belongs to box 1.

This one's fairly easy.

If the labels are surely incorrect, just pick an item from the nails and screws. If its screws, then interchange it with the screw label. Then, put the nail label where it was previously screws. The previous nail box is the nail and screw.

Interchange it if you picked nails.

We know all the boxes are incorrectly labelled.

We know we can't shake the boxes, look into them or take out more than one item.

There is no rule, however, stating that we cannot feel around inside the chosen box when we reach inside it.

Reach into the box labelled "Screws". Since we know it's mislabelled, it would have to contain either Nails or Nails & Screws. Since the nails would be thinner, they would drift to the bottom of the box, & the screws would be on top. Ergo, if you reached in & were able to feel a number of nails, you would know it should be labelled "Nails". If you felt screws & knew the box was mislabelled, you would know to label it "Nails & Screws".

Taking the first case as an example, remove the Screws label from Box 2. Then take the Nails label from Box 1 and place it on Box 2. Since Box 3 is also incorrectly marked, and Box 2 is now OK, you just switch the label on Box 3 to Box 1 & put the Screws label on Box 3.

Ireally did this off the top of my head - hope I'm not missing something.
