Hmm, being pedantic, that study is not even correct.

Editing slightly:

Dave takes an Italian dictionary weighing a certain weight
He also takes a French dictionary
In total, he is carrying 14 kg of books
Anna takes Dave's French dictionary and a German dictionary
The German dictionary weighs 2 kg less than the Italian dictionary
How many kilograms of books is Anna carrying?


We know Dave is carrying 14 kg of books, but we do not know whether he is carrying any other books, so all we know is the Italian and French dictionary combined weigh less then or equal to 14 kg.

We also do not know how many books Anna is carrying, so anywhere from grams (dictionaries in microfiche) to however much you can cram into a backpack and still carry.
