Answer:
1. Vaguely
2. Happily
3. Willingly
Step-by-step explanation:
Vaguely means the opposite of specific, which doesn't go with the other words that basically mean specific.
Bled happily doesn't make sense, bleeding isn't happy. The other three words are negative
People can laugh bitterly, touchingly, and sadly, but I haven't seen "laughed willingly" in a sentence before
