Highlight the 2 complex sentences in the text below.

Response: The two complex sentences are:

Due to the inadequacy of general ventilation in maintaining control, we strongly advise that additional fans and vent systems be installed at all welding locations.

As individual team members will initially be accountable for their own safety, ensuring that welders receive proper instruction and training regarding these controls is essential.

Clarification:

A sentence is regarded as complex when it comprises one independent clause and at least one dependent clause. An independent clause is a set of words that can function autonomously as a complete sentence. Conversely, a dependent clause fails to communicate a complete thought and cannot exist independently.

In the aforementioned sentences, the second and last ones qualify as complex sentences. They both commence with a dependent clause incapable of being a standalone statement, followed by an independent clause.
