A student did an experiment with two identical fish tanks, Tank 1 and Tank 2. About 10 ml water purifier was added to Tank 1. The water purity of each tank was tested every day in
particles per liter. The purity was recorded over a period of 5 weeks in the table shown below.

The conclusion that is correct about the experiment with two tanks, is adding water purifier keeps fish tanks clearer for longer.

What is an experiment?

An experiment is a practical task that is done to get to know the result. Experiment is performed with proper equipments, chemicals, subjects, and everything is note down to summarize the result.

Given that the data for 10 ml and 20 ml water purifiers are equivalent, it is advised to use 10 ml purifier for fish.

The data initially showed no change, but when the following week's data was recorded, it revealed a little increase in tank 2's value while both tanks had the same value the previous week.

Accordingly, we may infer that employing a 10 ml purifier is sufficient for the fish to survive.

Thus, the correct option is A, adding water purifier keeps fish tanks clearer for longer.
