Answer:
1. c) the mountain and a squirrel.
2. b) the squirrel.
3. False.
4. c) big.
Explanation:
From the passage we can deduce the following points;
1) The quarrel was between the mountain (former) and a squirrel (latter).
2) Little Prig' is the squirrel. According to the passage, the latter is the squirrel.
3) The mountain didn't say, ''If I cannot carry forest on my back." This phrase wasn't stated in any part of the passage.
4) You are doubtless very big. The adjective in this sentence is big because it qualifies a noun such as the mountain.
