Answer:
a.
Explanation:
The validity of a personality test is best indicated by the correlation between test scores and some other relevant measure. This is because, like any other test, the validity of something is determined by whether or not the test actually measures what is is meant to measure correctly. Therefore to determine the validity of the personality test, test scores must be compared alongside another type of measurement regarding personality.

If dichloromethane is swapped out and ethyl acetate is used in its place, the extracts then obtained would be highly anti-radical and would be more efficient than dichloromethane.
Since "like dissolves like," ethyl acetate is a polar molecule that works well as a solvent to extract the polar caffeine molecules from coffee beans. The ethyl acetate molecules bind to the caffeine molecules, which then move through the bean cells' cell membranes. After all, the ethanol:water (1:1) solvent combination has been demonstrated to be the best for recovering catechins and delivering extracts with the highest antiradical activity.
Dichloromethane is a volatile colourless liquid used as an organic solvent in many industries. One of its main application is that it used to extract caffeine because of its highly effective solvent nature. Because DCM is a non-polar solvent and caffeine is readily soluble in DCM, it can easily be extracted without losing its aroma.

Answer:
anxiety and novelty seeking
Explanation:
Anxiety will create a general discomfort that can happened in many instances (maybe in social situations, when learning something that they're not comfortable with , etc.) In some cases, they responded to this anxious behavior by seeking novelty as new source of excitement to replace their anxiety.
Among children, novelty seeking (excitement seeking) probably carried out by running around, pulling their friends' hair, screaming, etc.
But if this type of behavior is carried out until adolescence, the novelty seeking that they seek to address their anxiety could developed into things such as vandalism and substance abuse.
