When writing a claim you need to take a stance on a particular issue. In this case the issue is whether or not "standardized tests are the proper measuring sticks for student performance." This stance should be the first part of your claim. Then follow it up with "because..." and your three reasons. For example, Standardized tests are a proper measuring stick for student performance because they can test a student's knowledge on a wide range of subjects, they are the same for everyone, and they are an accurate indicator of how well a student will do in their future studies especially for fields like medicine and law.
C is definitely correct, but i’m not sure if any of the others apply because i can only find an excerpt of “what is apartheid?”. I hope that helps at least a little
i believe that the source that would best help students build background knowledge about bullying to better understand the news articles about bullying is a play about a girl who is creully teased. I believe this because if srudents wacthed it then they would realize that bullying or teasing someone is mean and rude and they wouldnt like it if they got bullied or teased
