Question : Select the most appropriate option to fill in the blank.
The researcher team took air ______ from the room every five minutes to rule out the possibility of a virus.
Option 1: instances
Option 2: slices
Option 3: samples
Option 4: droops
Correct Answer: samples
Solution : The correct option will be the third option.
In the context of scientific research and testing for the presence of a virus, samples refer to a small portion or representative selection of air that can be analysed.
Instances, slices, and droops do not convey the idea of collecting a portion of air for testing in the same way that samples do.
Therefore, the right word to fill in the blank is samples.
