In the medieval times, AKA the feudal system trade was very high because it was needed to get goods the kingdoms were more like places you were forced to live and without trade, you would never get food or clothes. You made less than a penny a day this could pay for a loaf of bread at the end of the week you got one pair of shoes a year and 2 pairs of clothes. When the trade went up it eventually ratified the need for all the work in the kingdoms.

NARA [144]

Answer:

<h3>d. extraneous.</h3>

Explanation:

Extraneous variables are variables which occur unintentionally while doing a research. When a researcher tries to find if an independent variable has an effect on a dependent variable, they may be chances that unexpected variable might occur which may affect the results of the research.

Here, the researcher who measured aggressive responses by people when exposed to violent and non-violent movies did not take into account the room temperature.

The room temperature may act as an extraneous variable which may have an effect on the result of his experiment.
