Question

Which one of the following sentences is a sentence fragment?

Finishing all ten Units will be very challenging.


Wanting to finish Unit 6.


Work to finish at least Unit 6.


The Unit 6 writing prompt is challenging.

Answer 1

“Wanting to finish Unit 6.” is the sentence fragment as it lacks a subject.

You might think “Work to finish at least Unit 6.” does that too, but as it’s a command, there is an implied subject—that subject being “you”.
