OA is A.

The explanations above focusing on the subjunctive are correct.

Solution: The original sentence is grammatically and stylistically acceptable. The subjunctive verb "provide" is required because of the word "demand." Two independent clauses are correctly separated by a semicolon. Answer (B) is incorrect because the clause "an American adoptive parent...." must be introduced by the word "that." Answer (C) is incorrect because the "actions" referred to in this sentence are not as clearly defined as they are in the original sentence. Answer (D) is incorrect because the section after the semicolon is a phrase, not an independent clause. A semicolon cannot be followed by a sentence fragment. Answer (E) is incorrect because a subjunctive very is required after the word "demand." "an American adoptive parent provides" would be correct if it stood alone, but the correct subjunctive verb is "provide."
