Hello. I don't know what evidence you mentioned in your previous assignment, which makes it impossible for me to answer your question efficiently. However, I will try to help you in the best possible way, showing you how to justify the chosen doubts.
you must justify the evidence based on the importance it has in the story you read. If you selected evidence where Douglass reflects on the importance of education, you can justify it by using the fact that education is liberating and would allow slaves to have enough knowledge to fight for themselves. If you used evidence about the misrepresentation that slavery imposes on society, you can justify how slavery is based on dominance and humiliation, generating results as depressing as the process itself.
False courage will be the answer<span />
I think the Arabs think that Santiago and the alchemist are spies. They allowed Santiago and the alchemist to keep the treasure because both have claimed that treasure doesn't have to be something material. The treasure can be something spiritual.
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.
