Final answer:
Jose's action of using his thumb and forefinger to show the thinness of his iPhone serves to complement and illustrate his verbal message. This form of nonverbal communication enhances understanding of the iPhone's design, which is a culmination of physics, technology, and international collaboration.
Option 'a' is the correct.
Step-by-step explanation:
When Jose is describing his new iPhone and uses his thumb and forefinger to demonstrate how thin it is, his action functions to complement and illustrate. This nonverbal communication is used to visually demonstrate the thinness of the iPhone, complementing his verbal description.
By using a common gesture, which is the opposition movement of the thumb toward the fingers to show dimension and size, he provides a clearer understanding of his verbal message.
Nonverbal communication can serve various purposes in conversation, including complementing verbal communication, substituting verbal messages, regulating interactions, and contradicting the spoken word. In the context provided, since there is no indication that Jose's gesture is replacing words or controlling the interaction, nor is it contradicting his message, the most appropriate option is that it serves to complement and illustrate his verbal description of the iPhone's thin profile.
The Apple iPhone is known for its sophisticated design and advanced features, such as a GPS function. The iPhone's slender build is just one of the many aspects meticulously engineered, combining physics, technology, and design aesthetics. iPhones, created using global resources, illustrate how comparative advantage influences global production, with countries like the United States, China, and Korea specializing in design, assembly, and component manufacturing, respectively.
