I was studying pronouns from MGMAT SC guide and had a doubt in below:
the GMAT insists that any “New Copy” that or those agree in number with the previous
version. If you must change number, repeat the noun.
Wrong: Her company is outperforming THOSE OF her competitors.
Right: Her company is outperforming THE COMPANIES OF her competitors.\
In the corrected version "company" and "the companies" do not agree in number.
Can you please explain this.
