Many schools have their art programs removed in an effort to improve test scores and save money. However, some researchers believe that this is not correct. Students can master some basic skills in art class that they cannot find in a normal classroom.
Allow me to share why you have to take art class.
First and most important, it stimulates creativity（激发创造力）.Art schools encourage you to think outside the box and be creative enough to create something artistic. It can be used not only in art but in life, too.
Besides, it helps you make the right choice. In art class, you are usually free to do what you want. In every art class, you are required to make decisions that can determine what your painting will turn out to be.
In addition, students can learn the art of critical（批判性的）thinking as a skill of observation（观察）. For example, art students find ways to imagine. That is a skill they need to become better readers and problem settlers.
What is more, it is noted that the company's bosses are actively looking for employees who can think creatively. Creative thinking is one of the most important skills that students can learn in art courses.
Finally, students who are trained in art class have interesting mental habits. They learn how to work on a task for a long time and how to continue to work even if they are discouraged. They are better for creating a link between the classroom and the outside world. In addition, children who do art work are able to look back on their work and make judgments about themselves.
What is the most important quality students develop in art class?（ ）
事实细节题。由第三段第一句可知，首先且最重要的一点是艺术课可以激发创造力。故C正确。
把10gMgCl2和MgSO4的混合物溶于适量水中，滴加2mol／L的BaCl2溶液至沉淀完全，共消耗BaCl2溶液25mL。求混合物中MgCl2和MgSO4的质量各是多少克
