(简答题)A市甲公司向B市乙公司购买10台专用设备，双方于7月1日签订了买卖合同。买卖合同约定：专用设备每台10万元，总价100万元；乙公司于7月31日交货，甲公司在收货后10日内付清款项；甲公司在合同签订后5日内向乙公司交付定金5万元；双方因合同违约而发生的纠纷，提交C市仲裁委员会仲裁。

7月3日，甲公司向乙公司交付了5万元定金。

7月20日，甲公司告知乙公司，因向甲公司订购该批专业设备的丙公司明确拒绝购买该批货物，甲公司一时找不到新的买家，将不能履行合同。

7月22日，乙公司通知甲公司解除合同，定金不予返还，并要求甲公司赔偿定金未能弥补的损失。甲公司不同意赔偿损失，乙公司遂向C市仲裁委员会申请仲裁。

对于乙公司的仲裁申请，甲公司认为：(1)只有当合同履行期满甲公司未履行合同，乙公司才可以解除合同，所以，乙公司于7月22日主张解除合同不合法，应承担相应法律责任；(2)即使合同可以解除，那么合同被解除后，合同中的仲裁条款即失去效力，所以，乙公司应向A市法院提起诉讼；(3)甲公司愿意承担定金责任，但乙公司不能再要求甲公司赔偿损失。据查，甲公司不履行合同给乙公司造成10万元损失。

要求：

根据上述内容，分别回答下列问题：

(1)乙公司7月22日通知解除合同是否符合法律规定?简要说明理由。

(2)甲公司主张乙公司应向A市法院提起诉讼是否符合法律规定?简要说明理由。

(3)甲公司认为乙公司不能要求赔偿损失是否符合法律规定?简要说明理由。

【简答题】Re-Entry Students Re-Entry students have a positive effect on college students, instructors, and the community. They are called “re-entry” students because they have been out of school for a period of time and have come back. Often students take college courses and then leave school for a variety of reasons: jobs, military training, family obligations, indecision about careers. No longer are college classes primarily made up of 18- to 20-year-old recent high school graduates. In many colleges, the average age of all students is approaching 30 years. Occasionally a student graduates from college for the first time at the age of 70 years or older. For younger students, re-entry students are often models of dedication and hard work. Returning men and women help set a mature tone in the classroom, and their life experiences add to the enjoyment of class discussions. Instructors often notice improved student interaction in a class with a wide variety of ages and backgrounds. Students who have had careers in the workplace, the military, or as homemakers add a wealth of information and perspective to a class. Finally, the community benefits from better-educated citizens of all ages. Private businesses and government agencies get workers with better skills and the community gets better-informed citizens and voters. When students re-enter college to improve their lives, they also improve the lives of countless others.
