Question

read the sentence carefully. which revision corrects the error?
practicing every day in the opinion of most teachers improves the chances of becoming a professional musician.
○ practicing, every day in the opinion of most teachers, improves the chances of becoming a professional musician
○ practicing every day in the opinion of most teachers, improves the chances of becoming a professional musician
○ practicing every day, in the opinion of most teachers, improves the chances of becoming a professional musician
○ practicing every day in the opinion of most teachers, improves the chances, of becoming a professional musician

Explanation:

The original sentence has a misplaced parenthetical phrase "in the opinion of most teachers" that disrupts the main clause flow. This phrase is a non-essential comment, so it should be set off with commas from the main clause "Practicing every day improves the chances of becoming a professional musician". The correct revision places commas around the parenthetical phrase to separate it properly without breaking the main sentence structure.

Answer:

Practicing every day, in the opinion of most teachers, improves the chances of becoming a professional musician.
