Honestly this question doesn't make sense but if its a legit question then the answer would be A
The statement, which best describes the evidence that Group 3’s data are less valid than the data for the other two groups is this: GROUP 3’S pH VALUE FOR VINEGAR IS MUCH HIGHER THAN THE VALUES OF THE OTHER TWO GROUPS.
An experimental result is said to be valid, if it gives the true values of the parameters it has measure. Looking at the experimental results given in the question above, one will notice that, the pH value obtained by group 3 for vinegar is quite different from that of the other two groups. In addition, the value is wrong, this is because, vinegar is acidic in nature. The result obtained by group 3 indicates that vinegar is basic, which is wrong. This shows that the results obtained by group 3 is less valid than that of the other two groups.

To safeguard against ground water contamination, sanitary landfills are lined with plastic and clay. Ground water is the water beneath Earth's surface in soil pore spaces and in the fractures of rock formations.Water that falls as precipitation flows along the surface of the ground. This surface water infiltrates into the ground surface and is held in soil pore spaces and in the fractures of rock formations. To gain access to this water sources it requires digging or drilling the ground and into an aquifer.
