The sentence provided has multiple clauses including at least two independent clauses and one or more dependent clauses. "When I arrived at the office," is a dependent clause, "I found that the principal was out" is an independent clause, and "apparently, he had contracted the same sickness as half the school" is another independent clause. This makes the sentence a compound-complex sentence.
