<p>Until It<a href="A">/U</a> can be replaced by a faster<a href="B">/U</a>, more efficient, and more economical means of transportation, trucks will carry most<a href="C">/U</a> of the freight within and through<a href="D">/U</a> metropolitan areas. (E) No Error
The answer is A, can someone explain to me why?</p>
<p>I think it’s because ‘Trucks’ is the subject so you would need a plural pronoun. ‘It’ doesn’t correctly refer to ‘Trucks’.</p>
<p>Wait till Silverturtle or someone makes an appearance though because grammar isn’t my thing.</p>
<p>(A) should be “Until they”.</p>
<p>oh ic now, that makes sense haha. thanks</p>
