According to anthony platt, author of the child savers: the invention of delinquency, the progressives were not children, but denying them what?

Civil liberties.

Explanation:

Anthony Platt's classic work (1977), The Child Saver The Invention of Delinquency is a study that describes the "child-save movement" advocated by progressives, not as an attempt to liberate and dignify children, but as a form of denying the civil liberties of these children. According to the author, child-save movement is a punitive, romantic, and invasive effort to control the lives of poor urban children and adolescents to perpetuate the dependency status of subordinate classes.

The child-save movement consisted of the creation of reformatory systems, the practice of juvenile offenders, and the juvenile court system. According to Platt, using this discourse of victimization, this movement was not a humanitarian enterprise in favor of children, but was a form of social control, idealized by elites, aiming to subject a population to the demands of the emerging capitalist system.

light-year  

the distance that light travels in a vacuum in one year, equal to about 9.46 trillion km (5.88 trillion mi). light-years are used in measuring interstellar and intergalactic distances.  

parsec  

a unit of distance used in astronomy, equal to about 3.25 light years (3.08 × 1016 meters).  

parallax  

the apparent angular displacement of a celestial body due to its being observed from the surface instead of from the center of the earth (diurnal parallax or geocentric parallax) or due to its being observed from the earth instead of from the sun (annual parallax or heliocentric parallax)  

absolute magnitude  

the magnitude (brightness) of a celestial object as it would be seen at a standard distance of 10 parsecs.  

apparent magnitude  

the magnitude of a celestial object as it is actually measured from the earth.  

redshift  

an increase in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect.  

the great thing about your imagination is that it doesn't have to make sense! if i were you i would be stuck in space, no communication with earth travelling around and around, you can only guess how long its been since your communication broke down. you land on an undiscovered planet, you do a scientific investigation examining the elements and conditions. you come across alien lifeforms.  

best of luck!
