Final answer:
The sentence in question is not a simple sentence but a compound sentence because it contains two independent clauses joined by a coordinating conjunction.
Step-by-step explanation:
No, the sentence "Fabio has worked so hard over the last four years; however, he's also had his share of shortcomings" is not a simple sentence. A simple sentence consists of only one independent clause, which means it has a subject and a predicate and expresses a complete thought.
The given sentence contains a coordinating conjunction (“; however,”) which connects two independent clauses, making it a compound sentence.
The given sentence 'Fabio has worked so hard over the last four years; however, he's also had his share of shortcomings.' is not a simple sentence because it contains a semicolon and a coordinating conjunction ('however').
A simple sentence consists of a single independent clause, which means it must have a subject and a predicate and express a complete thought.
An example of a simple sentence is 'Fabio has worked so hard over the last four years.'
