A factory installs a new energy-saving machine. This technological change is most linked with which result?

Correct answer: Reduction in operating cost

The direct answer is option B: reduction in operating cost. A technological environment includes machines, methods, and tools used to produce goods. An energy-saving machine uses less electricity or fuel for the same work, so the factory spends less during daily production. That daily spending is part of operating cost. Option A, end of law, is unrelated: technology does not automatically abolish laws. Option B is correct because saving energy directly lowers a running expense and may also improve efficiency. Option C, increase in festival demand, depends on customers and seasonal buying, not on the machine itself. Option D, change in voting process, belongs mainly to the political environment, not the technological result described here. A good exam link is: efficient technology can reduce cost, save time, improve quality, and increase productivity. Memory cue: energy-saving equipment means lower use of energy and usually lower operating expense.
