<u>Explanation</u>:
The text was written in <u>Catalan language</u>. A clearer rendering of the text reads;
<em>"Like so many other animals, humans are capable of emitting sounds through the interaction of various physiological organs, which also participate in other primary functions such as breathing or the swallowing. The founding apparatus is that complex system by which air is transformed into sound and sounds into emotions."</em>
You now probably required to make inferences or deductions from the statement above.
