Answer:
I know its been 2 years, but its A
Step-by-step explanation:
If you read the excerpt you will see multiple mentions of what a fountain would be, for example, '' gushing, gurgling ''. If you didn't understand that, lets do process of elimination.
B) Song.
Read this. '' In the following lines, the author compares a bobolink to a ''Song'' to describe the liveliness of the bird's song. '' That wouldn't make sense.
C) Flood.
I could see this being my answer if fountain wasn't an answer, but fountain would make more sense due to the mentions of it.
D) Meadow.
I dont think meadows gurgle or gush.
Therefor, A) Fountain, would be the best answer. :)
