From this passage we can infer that ________.

The passage begins with Amy shouting Blue's name and bounding through the meadow. This suggests that she is looking for him. Amy is out of breath and her voice is becoming hoarse, which suggests that she has been running for a while. Amy says that her mom and dad said not to venture to the meadow, which suggests that she was not supposed to be there.
The passage does not explicitly state that Amy lost Blue, but all of the clues above suggest that this is the case. It is also likely that she is frantically shouting for Blue because she is worried about him, and she knows that she is in trouble for being in the meadow.
