All of these choices are correct. US Government posters during World War II often displayed slanted language, ethnic biases and nationalistic biases.

Explanation:

The posters placed by the federal government on public roads, transportation and other places of high circulation of people during World War II had as their main and fundamental objective the creation of a united and strong domestic front, where all citizens collaborated with the effort of the thousands and thousands of Americans on the battlefront through the production of food, medicine, supplies, and weapons, and the rationing of their own consumption in order to allocate most of the resources to these soldiers. In addition, these posters attempted to encourage many young Americans to join the ranks of the military, by spreading nationalist (such as Uncle Sam and his "I Want You" message) and ethnicists slogans (such as posters depicting Japanese and Germans as sadistic and evil beings).

All this propaganda was effective in its initial purposes, since it generated a feeling of union and collaboration that allowed a greater allocation of resources for the armed forces that were fighting in Europe and the Pacific.

in a biology class, the teacher started explaining a new lesson about the dna structure. personally, i found this lecture hard to understand. so i decided to use my critical thinking skills to be able to understand it. i analysed the different ideas, and broke them down into smaller parts to assimilate each. then i started evaluation and tried to link what i am learning with real life experiences so that i can make sure that i know how everything i am learning relates. finally, i started questioning by researching more what i learned and asking more questions that can me through my learning process. reflecting on the information meant that i should review it. all this me greatly understand what i previously found hard to understand.

hope it !
