What is the analogy in the road not taken. Please explain I will mark branlist

The road less taken compares the choice that less people take typically because it is more difficult. The writer is saying he will not conform to what others are doing.

Hope this helps

everett ross tried the pasta but liked the soup more

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."
