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.

This project was designed to bring back the jobless workers into work by providing employment in different sectors. It employed around 4 million unemployed workers during the Great Depression period in the constructions of tunnels, highways and also in the construction of the courthouses and the airports.

The correct answer is that Jane is more friendly and sociable than Denise. When we get a positive stimuli from a person, we are more likely to open up and feel happier which will lead to us being more sociable to other people. When we feel that the other person does not like us, we tend to close up, doubt ourselves and therefore look less friendly.
