Final answer:
The claim about Carrier Ethernet services is false. High-voltage wires are not wrapped in insulation, making that statement false. The statement about refraction being useful in fiber optics is true and the description of electric field lines from a positive point charge is also true.
Step-by-step explanation:
The statement regarding Carrier Ethernet services is false. Carrier Ethernet services are known to include options such as E-line, E-LAN, and E-tree, but there are no standard services known as E-asymmetric or E-motive in Carrier Ethernet. Instead, other services exist, but the names provided are incorrect in the context of widely recognized Carrier Ethernet services.
Referring to the additional information: High-voltage wires are indeed supported by insulating connectors but they are not wrapped in insulating material; they are typically bare. Thus, that statement is false. Furthermore, refraction is an essential principle for fiber optic cables as it allows signals to be transmitted via light, showing that the statement concerning refraction being useful in fiber optic cables is true. Lastly, the electric field lines from a positive point charge do spread out radially and point outward, so that statement is also true.
