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.
The answer is false because if you do it is called plagerism
1. I am not sure why I can't go to the movies.
I don't eat ice cream because I am lactose intolerant.
2. The book's cover was blue and white.
3. The students' grades were at an all-time low.
The children's toys were across the room.
4. She got three A's on her report card.
Hope this helps and hope you have a great day!!
