Question

Fast-forwarding to modern times, the heyday of the human-powered flight is far from over. Lucrative prizes still abound for rotor-driven craft, whilst experimental versions of helicopters and ornithopters (flying machines with flapping,bird-like wings)are both on the drawing board and leaping off it with great abandon. The dream of human-powered flight has been an official reality now for more than 50 years, but the limits of their ingenuity are boundless- especially when inventors and engineers are spurred on by prizes as large as the $250,000 on offer from the American Helicopter Society Igor Sikorsky Prize Fund. And who knows, perhaps one day his commute to work will take place not on a bicycle but on a bicycle-powered craft. Does your office have a landing pad on the roof or a runway nearby? The day when she does might just be closer than they think!

Answer 1

The four pronoun-related errors in this paragraph are,

1. Limits of their ingenuity -- its, replace by their (the dream)

2. one day his commute -- our, replace by his

3. when she does -- it, replace by she

4. closer than they think -- we, replace by they

What are pronoun-related errors?

Pronoun errors happen when a pronoun does not agree with its antecedent, which can create confusion in your writing. Pronouns are generic noun replacements such as him, her, it, and them. An antecedent is the noun that the pronoun replaces.

Some of the most common grammar mistakes are pronoun errors. They occur when pronouns do not agree in number with the nouns to which they refer.
