I'm having a problem with 3:
"Diana will destroy those hostile to latona."
Key: Diana inimicos Latonae delebit.
Tim: Diana eos inimicae Latonae delebit.
When I first checked this I was surprised at how far I was from the key. When this happens I usually spend some time reviewing the material until I have a full explaination. But in this case I am having a cascade of questions and I'm getting a bit boloxed up. Here's my anaylsis and I hope someone can point out where I go wrong.
Divide and conquer
Break the sentence into it's basic parts:
"Diana will destroy those."
This closely resembles the sentence for §117.1
"He praises them."
The three genders are because the demonstrative pronoun "them" is indefinite and should match a antecedent noun to which it refers. Since we have no context here, all three are possible. Also, an alternate translation of them is those. I also note that all three are in the accusative case. This matches with the first dative example (§44) Nauta fugam nuntiat.
From this I get:
Diana delebit eos/eas/ea.
Adding the "hostile to Latona" is the dative with adjective,
Diana delebit eos/eas/ea inimicae Latonae.
The lesson rule §146 says to use the dative case of the adjective to denote the object to which the quality is directed. That would be Latona, also in the dative as the indirect object (§44). I matched genders as well, although I can't see any reason why I could not match it with the direct object, which in this case is "them." Ugh! Hence I picked the feminine.
I cannot explain the use of the masculine/neuter accusative inimicos. I thought it might be a match to Nauta fugam nuntiat, however, the match fails to me because the direct object here isn't "hostile", but "them". "Them" answers the question Who?
I also cannot explain the dropped "them" since we do have the demonstratives.
Again, it was because my answer was so far from the key (in some of the other questions as well) that I began to doubt whether I understood the lesson.
