Investigators are working on a case where they need to know whether a watch will stop when it is dropped. In order to have a verified or reliable answer to this question, what should they do?

Call the manufacturer to ask whether it will stop under these circumstances

Drop a similar watch multiple times and record the results

Consult with more senior forensic scientists for their experiences

Take the watch apart and test the mechanism to see what causes failure

In order to have a verified or reliable answer to this question, they should take the watch apart and test the mechanism to see what causes failure.

Answer: Option D

Explanation:

For dropping a similar watch to record results, we need to buy another one. So, it becomes expensive. And, calling the manufacturer will give accurate results, but no knowledge. It is like getting multiple choices by luck.

Consulting senior faculty won't result in any progress, because they may not have conducted these. So, one should rip off the watch, and study the mechanism, and its limitations. The testing of mechanism gives the actual results.

Answer: B) Drop a similar watch multiple times and record the results.

Explanation:

In order to have a verified or reliable answer to this question, investigators must drop a similar watch multiple times and record the results. By doing this and repeatedly getting the same result (s), they are able to determine that their answer is in fact true.
