<h2>Answer: D The management of publicity</h2><h2></h2>
The correct answer is; Plank.
Further Explanation:
North Carolina started building plank roads in the late 1840's. These roads were easier to maintain and easier to drive on. Before the plank roads were built, the roads had long muddy roads and large holes and ruts that drivers had to navigate through.
The crews could only lay an estimated 40 miles of plank roads per year and this did cause issues. North Carolina had the largest plank road with a total of 500 miles built. The rods failed after a few years because it took so long to build.
Citizens were then using the railroad system since it was faster than traveling by horse and buggy. The people also did not like having to stop at the toll booth that had been set up on the road. The money collected at the toll booth was used to pay for maintenance of the plank road.

Answer:
The answers are:
a. dependent
b. independent
c. test
d. control
Explanation:
In scientific research, investigations are done to study whether certain factors change while changing others, and the following terms are associated with scientific research:
a. dependent variable: These are factors or outcomes that are being investigated in a research experiment, and they are not under the direct control of the researcher. They are factors that vary as a result of other changes made in the process. In our example, the heart rate and blood pressure are proposed to vary with the type of film watched hence these factors are dependent variables.
b. independent variable: Independent variables are variables that are under the direct manipulation of the researcher, and the predetermined variation of these variables cause certain effects on the dependent variables. In our example, the type of film is the independent variable, because the researcher has complete control over the type of film watched.
c. Test group: These are the group of participants/individuals in research, who will potentially be affected by the change in the dependent variable to cause an effect that deviates from the normal. In our example, the group that views the violent film is the test group, because there is a tendency that they might have altered heart rate and blood pressure as a result of the type of film viewed.
d. control group: The control group is the group of individuals whose effects at the end of the experiments will serve as baseline effects, to serve as a means of measuring the magnitude of variation in the test group. These groups serve to eliminate any other effects that might cause similar changes as the factor being investigated in all test participants.
