The excerpt from <span>"The Enigma Machine” that supports the idea that Allied forces expected the Germans to complicate their coding system is the following: </span>
"The Germans
knew their enemies were listening to their secret radio com<span>munications,
but they were confident their messages were undecipherable.</span>
The ENIGMA
machine so enciphered the messages that the Germans assumed <span>the contents
could be deciphered only by duplicate ENIGMA's set according </span><span>to precise and frequently changed settings."</span>
The question is a bit vague, but I'd say D because a monster who saves a child and then gets shot by the father would surely contribute to "monsters' hatred of humans"
