Question

Which of the following statements is the best example of informal syntax •if you want to go fast,go alone.ifyou want to go far , go with others •everyone is wise until he speaks •the front don’t drink up all the pond where he’s living at •do not confine your children to your own education; they were born in another time

Answer 1

The correct answer should be - The front don’t drink up all the pond where he’s living at.
This sentence is informal because of two reasons: 
1. the front don't - this should be the front doesn't
2. where he's living at - in formal syntax, a sentence cannot end with a preposition
