The control variable is the factor that remains fixed in an experiment. It is not changed, ensuring observed effects are caused by the independent variable and not another factor. Examples include time, temperature, and location, depending on the experiment.
In an experiment, the factor that remains fixed is known as the control variable. It is the element that is not changed throughout the experiment, ensuring that the observed effects are caused by the manipulated variable - the independent variable - and not another factor. For example, if you were conducting an experiment to see the effect of sunlight on plants growth, the type of plant used would be a control variable, as you would use the same type of plant in all instances. Other examples of control variables could include time, temperature, and location, among others, depending on the specifics of the experiment.

Answer:
Abuse of power
Explanation:
The major condition that was responsible for the rapid growth of railroad industry was that the government started granting massive land easements to the railroads for free.
This was the most important part of the equation. Without the land grants all the other technological points were mere points of interest. Railroad owners sold stock to investors to finance the construction of railroads.
Caste and feudal system are social hierarchies which means people are based on social significance.
Explanation:
Both caste and feudal systems have four categories. Caste system has Brahmins, Kshatriya, vaishyas and shudras. Feudal systems has kings, nobles, knights and peasants. Persons class determined the occupation he took up and he attains pride based on the job he does. people who do menial jobs are treated in a different manner. Power was based on the class which the individual belong to.
There was no improvement of the people moving to the next strata in the society. Caste system was based on religion while feudal system was based on the Catholic church belief. Feudal system ended but the caste system still prevails in India.
The feudal social structure and the Hindu caste system entail rigid hierarchies based on birth, predetermined social roles, and limited opportunities for social mobility.
Both the feudal social structure and the Hindu caste system are hierarchical systems that determined an individual's social status, rights, and roles within society. In the feudal system, the hierarchy was based on birthright, loyalty, and military service from serfs at the bottom to the king at the top. Similarly, in the Hindu caste system, individuals are born into a specific caste, such as Brahmins (priests and scholars) at the top and Shudras (servants) at the bottom, determined by birth.
Another similarity is that both systems were remarkably stable and rigid, with little chance of movement between levels. In both the feudal structure and the Hindu caste system, social mobility was limited and your status in the hierarchy often dictated your profession, social ties, and even your spouse.
