Answer:
Option B. The following change needs to be made to the passage: The word "dont" should be changed to "don't".
Step-by-step explanation:
The word "dont" as it appears in the passage is written with a grammatical error, as the correct way of writing it is with an apostrophe before the t (don't). "Don't" is a contraction of the phrasal verb "do not", that is generally used in English in order to construct a negative sentence, like the one in the passage; "I don't really know how I wound up working for my dad." In order to correct the passage, the writer should change the word "dont" to the proper form that is "don't".
