The first sentence: "Marco rode to school on his bicycle this morning, he arrived an hour early."

Reason: it joins two independent clauses with just a comma (a comma splice). Fixes: use a period, semicolon, or add a coordinating conjunction — e.g. "Marco rode to school on his bicycle this morning. He arrived an hour early." or "Marco rode to school on his bicycle this morning; he arrived an hour early."
