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.
Answer:
The dairymaids possessed immunity against the more extreme smallpox as due to getting exposed to cowpox, the body of the dairymaids generated certain kinds of substance to defend against the cowpox, which also helped in defending smallpox.
When Edward Jenner found that the dairymaids suffering from cowpox possessed immunity towards smallpox, he concluded that the emergence of cowpox at the same time developed immunity towards smallpox. To ensure, Jenner collected a fluid sample from the pustule of cowpox and administered it within a boy's body, and thus, discovered the principle of immunity.
