Which method would you use to collect information about the actual and correct…

In research methodology, different techniques serve different purposes: the survey method is the tool used to collect standardized, factual information from a large number of people in a defined population, usually through structured questionnaires or interviews, so that a broad and comparable picture of everyone's current situation can be obtained.

Here, the requirement is to find out the actual, correct, current status of every earthquake victim across an area — a large population, not a single case. That calls for a structured way of reaching many people at once and recording comparable status information from each of them, which is exactly the role the survey method is designed for. So the survey method is the appropriate choice.

As a cross-check: does the task call for deep study of one unit, open-ended exploratory questioning, a hands-on constructive task, or a step-by-step fix to one difficulty? None of those match "systematically record status information from many people across an area" — only a structured, population-wide data-collection tool does, confirming the survey method.

• Inquiry method centers on open-ended, exploratory questioning to build understanding of a topic; it has no structured mechanism for uniformly canvassing a large population for status information.

• Project method involves an extended, hands-on investigation of a single theme or task carried out over time; it suits deep learning-by-doing, not quickly gathering status data from an entire population.

• Problem-solving method applies a structured reasoning process to resolve one specific difficulty; it targets fixing an issue, not canvassing many people to learn each one's current status.
