Answer:
Step 1: Identify which options are accurate
What will the economic situation look like in the future?
- Option A: too broad
How might virtual reality be applied in healthcare?
- Option C: effective
How many gallons of water will be consumed in 2025?
- Option B: too narrow
What are the optimal strategies for enhancing food production looking forward?
- Option C: effective
For the first question, it is deemed too broad as predicting the economy’s future is an expansive subject that cannot be sufficiently explored in a single inquiry. For the second question, it is considered effective since it's a well-defined research question within a broad area. The third query is viewed as too narrow because understanding the gallons of water usage in 2025 lacks relevance. Lastly, for the fourth query, it is effective as it also specifies a research inquiry within a particular topic.
