Answer:

7

Step-by-step explanation:

in 5 and 6 there are few flaws in their experiment, so there is no way to disprove the information they find. However in 7, the biologist can't prove that having 4 tagged fish out of 50 means there are 1,800 fish in that quarry. Therefore it is inaccurate and biased.
