Punctuation other than commas or semicolons (including hyphens and apostrophes)
Explanation:
The type of error this sentence contains would be the 'punctuation error.' The sentence exemplifies a complex sentence and therefore, it consists of a dependent clause immediately followed by the independent clause. According to the grammatical rules, the appropriate punctuation can a comma(,) or semicolon(;) after the introductory clause but the given sentence wrongly employs 'hyphens and apostrophes.' Thus this is a punctuation error.
