The answer key gives:
"Sī illī quattuor mīlitēs nōs secūtī essent, arma in nāve pōnere nōn ausī sumus."
Wait a sec. "Ausī sumus"? Since the condition uses the imperfect subjunctive, surely the conclusion should as well, making it "ausī essēmus"? I can't think of any way the indicative makes sense here.
This must be a pretty big blunder if even I can spot it...
Now I'm beginning to wonder about the quality of the other English -> Latin sentences in the answer key...
