1.) "Time is but the stream I go a-fishing in..."

2.) "The intellect is a cleaver..."

Includes them to give comparisons and examples.

Explanation:

The metaphors that Thoreau employs during the lines '99-105' of his book titled 'Walden' include the comparison of 'time with a stream' and the 'intellect  with a cleaver.' These metaphors not only help in making his experiences at Walden more lively through instances but also emphasizes his message of individualism, transcendentalism, the significance of nature, and self-reliance. It also highlights the leisure of living a simple and self-sufficient life and how one can understand the social world around him by introspecting himself from within.

the answer that is correct is the last option.
