wouldn’t the independent variable be just the student who are asked to sign in? Because, isn’t the independent the one that is being changed and the dependent variable is the one responding to the change? 
- A dependent variable is the variable that changes as a result of the independent variable manipulation. It's the outcome you're interested in measuring, and it “depends” on your independent variable.
 
 
        
             
        
        
        
This questions seems to be a question where you are required to mention more than one point. The question has two options of course, I'll tell you my personal answer to the question in broken up points.
I disagree with this statement because I believe that Physical Education (PE) is a very important subject for each individual. 
It has been proven that any sort of physical education improves the activity of your brain, if an individual's level of brain activity is higher, it means he learns more from other education and performs better on his tests. 
Physical Education is also a practical lesson that relieves stress off students from all the other core subjects that do not that involve as much practical activity.
Physical Education makes you healthier, the healthier you are the better your life style and (technically) life time will be.
Physical Education is also now proven to wake up students, this means students are less lazy and goes back to one of my previous points mentioning a students activity and performance in a lesson or a test.
I hope this helped, any other questions let me know. :3
        
             
        
        
        
According to Shondra's personal assessment, the most suitable career cluster for her would be:
Shondra is passionate about Justice and ensuring that people stay safe and treat each other fairly, so a career in law and safety would be relevant, as these career groups are activities that require a lot of responsibility, empathy and a sense of collectivity, for dealing with issues related to life, safety and factors that directly impact all areas of an individual's life.
A career as a physical educator would also be a good choice for Shondra, as she enjoys physical fitness and knows how to deal with high pressure situations, which are important characteristics in a physical educator, who needs to enjoy physical activities, be determined and handle with pressure to motivate and direct their clients.
Therefore it is essential that the choice of a career is based on the professional profile of an individual, there are several tests and competent institutions for the best career direction for students.
It is essential to carry out in-depth career research, talk to other professionals in the field, as this is a decision that will impact your life and can positively impact the lives of other people as well.
