Question

should demonstrate significance rather than simply restate a task. which revision best meets that goal? advancing renewable energy research will determine how societies meet future energy needs while balancing environmental and economic demands. technology keeps changing, so people will probably invent new tools for energy in the future. renewable energy is useful, but some people still prefer traditional sources of power for their homes. there are many opinions about renewable energy, and more people should discuss them openly.

Explanation:

The goal is to demonstrate significance, not just restate a task. The first option, "Advancing renewable energy research will determine how societies meet future energy needs while balancing environmental and economic demands," explains the importance of renewable energy research by linking it to meeting future energy needs and balancing demands, showing significance. The other options either state a fact (technology changing, people preferring traditional sources) or suggest discussion (opinions on renewable energy), which don't demonstrate significance as well.

Answer:

A. Advancing renewable energy research will determine how societies meet future energy needs while balancing environmental and economic demands.
