Question

question 1-54
core technologies, which are the building blocks of technology, are embedded within larger
mechanical, structural, and electrical systems
political, ethnical and moral systems not related to technology
technological, social, and environmental systems
optical, thermal and fluid systems

Explanation:

Core technologies are fundamental in technology and are integrated into various systems that are related to technology - mechanical, structural, and electrical systems are common larger systems where core technologies are embedded. Political, ethnic, and moral systems are non - technological. Technological, social, and environmental systems are too broad and not the most specific. Optical, thermal, and fluid systems are more specific sub - systems and not as general as mechanical, structural, and electrical systems for core technology embedding.

Answer:

A. mechanical, structural, and electrical systems
