Correct sentence: 'The study of French requires patience because the grammar rules are different from those of the English language.'
Explanation:
A fragment is defined as a 'part broken off or detached from a sentence that expresses an incomplete thought.' The given sentence exemplifies a fragment as it unncessarily employs a full stop(.) in the middle of a complex sentence which misleads the overall meaning of the sentence. In order to rectify this error, <u>the full stop can be removed so that the dependent clause 'because...language' accomplishes its meaning by linking with the principal clause</u>.
