Difficulty: MediumSubordination and Coordination

In 1915, chemist Alice Ball developed the first successful treatment for leprosy by isolating the active ingredients of chaulmoogra oil. Although her method became the standard of care for decades, but she did not receive immediate recognition for her breakthrough due to her untimely death and a colleague's attempt to claim the work.

Which of the following choices is the best replacement for the underlined portion of the sentence?

  1. A
    NO CHANGE
  2. Although her method became the standard of care for decades, she did not receiveAnswer
  3. C
    Her method became the standard of care for decades, she did not receive
  4. D
    Although her method became the standard of care for decades; she did not receive

Answer

Although her method became the standard of care for decades, she did not receive
The correct option removes the redundant coordinating conjunction 'but' from the second clause. This allows the subordinating conjunction 'Although' to properly introduce a dependent clause, which is correctly joined by a comma to the main independent clause that follows.

Step-by-Step Solution

1
Analyze the structure of the clauses in the original sentence.
The clause starting with 'Although' is dependent, while the clause starting with 'she did not receive' would normally be independent. However, the insertion of 'but' at the start of the second clause makes it coordinate, leaving the sentence without a main independent clause.
Every complete sentence must contain at least one independent clause to be grammatically correct.
2
Evaluate the choices to find one that correctly coordinates or subordinates the clauses.
The option that removes 'but' and keeps the comma correctly structures the sentence as a dependent clause followed by an independent clause. The option that uses a comma to join two independent clauses creates a comma splice. The option with the semicolon incorrectly separates a dependent clause from an independent clause.
Choosing the option that removes the redundant coordinating conjunction 'but' establishes a proper subordinate relationship between the clauses.
