Rosa judges everything serena does based on the fact that serena is an only child. rosa is engaging in which attribution error?

I believe the answer is: overattribution

overattribution refers to a social occurence when people believe they could freely express everything that they  want and assumes it's true and other people would believe it. This occurence considered to be a form of bias, and make people constantly give false characteristic toward others without having enough evidence.

"social stratification refers to the way people are ranked and ordered in society. in western societies, stratification is primarily seen and understood as a result of socioeconomic status, which produces a hierarchy in which access to resources, and possession of them, increases from the lower to the upper strata"

the correct answer is option c. elenita versus "early puerto rican decor" is the best example, out of all the options, of a cultural conflict. a cultural conflict is defined as what happens when different cultures, that have different values and believes, clash. elenita not liking or accepting the puerto rican style of decoration, would represent that she does not identify herself with the puerto rican culture, therefore does not want to have decorations influenced by that culture.
