34. read the following paragraph and complete the statement. choose the best answer based on the information in the paragraph.\n\nthin, flexible electronics can now be incorporated into textiles. optical fibers can be woven into the fabric, connected by conductive thread. a t - shirt with a microphone and a series of colored leds could become a mobile real - time noise level indicator. a motion sensor attached to a running suit threaded with fiber optics would provide night visibility for joggers. tech - integrated textiles are in their infancy, and the early applications are largely runway novelties or simple electronics projects.\n\nthe fabrics have ______ properties.\n\na luminous b insulating\nc corrosive d volatile
Answer
Brief Explanations:
The text mentions a T - shirt with colored LEDs and a running suit with fiber optics for night visibility, indicating the fabrics can emit light or be related to light - emitting features. Luminous means giving off light. There is no mention of insulating (resisting heat flow), corrosive (able to eat away at materials), or volatile (easily changing to a gas) properties.
Answer:
A. luminous
