Respuesta :
The underlined part of the passage is correct as is, as stated in option A, since the other options would actually make the passage wrong rather than correct.
Why is the passage correct?
The underlined part in the original passage is "who was made to understand." This part is correct as is because:
- "Who" must be used rather than "whom" since it is the subject of the clause.
- "Made" is the participle of the verb "make" while "maid" is a noun.
- There is no need for a comma to separate "who" from the rest of the clause.
With the information above in mind, we can select option A as the correct option.
