Select the most appropriate option that can substitute the underlined segment in the following sentence.
Although he was exhausted from working all day, John continues to study for his upcoming exam.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. continued to study for his upcoming exam.
The sentence starts with "Although he was exhausted," indicating past tense.
The phrase "continues to study" is in the present tense, which creates a tense inconsistency.
The correct past form should be "continued to study" to match "was exhausted."
Corrected sentence: Although he was exhausted from working all day, John continued to study for his upcoming exam.
Hence, the chosen option is correct.
