The error with the subject-verb agreement is "Here is the directions," since the singular verb "is" is incorrect, and the correct verb would be the plural "are".
<h3>What is subject-verb agreement?</h3>
Subject-verb agreement refers to the verb following the person and number of the subject. For example, the subject "I" is first person singular. Therefore, we cannot use "are," second person singular with "I". We must use the verb "am", which is first person singular as well.
That is why the section "Here is the directions" contains an error. The verb "is" is singular, but the subject "directions" is plural. The correct verb to be used is the plural "are".

Answer:
Experimental or treatment group
Explanation:
In science, researchers use different variables to test the cause or effect of a specific treatment or phenomena. These variables could be dependent or independent.
In these experiments, the control group refers to a group that does not receive any type of treatment or, in other words, does not receive any variable. On the other hand, the experimental group receives the treatment or variables and is the one that would show the results.
These two groups - control and experimental - are subsequently compared.
