We use information from which two sources in order to determine whether an author uses a word or phrase differently than we use it now? A) a dictionary and a thesaurus
B) a usage dictionary and a dictionary
C) the reading itself and a thesaurus
D) the reading itself and a dictionary

I strongly believe that this questions answer is B

We need to check a usage dictionary and a dictionary to get vocabulary which one used in the past. Some words means are same and some words look like same but they haven't same means for this we should check dictionary.
