Identify the error in the given sentence and select the option that correctly rectifies the error.
PIEZO2 plays an critical role along with Piezo1 to regulate a important physiological process for brain to understand.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2, i.e. “PIEZO2 plays a critical role along with Piezo1 to regulate an important physiological process for the brain to understand.'
There are two errors in the original sentence related to article usage:
- “an critical role” – “an” should be “a” because “critical” begins with a consonant sound.
- “a important physiological process” – should be “an important physiological process” because “important” begins with a vowel sound.
Option 2 corrects both errors:
PIEZO2 plays a critical role along with Piezo1 to regulate an important physiological process for the brain to understand.
This version uses the correct articles and makes the sentence grammatically sound.
