甲公司为房地产开发公司，自2011年3月开始销售其开发的住宅小区，并在媒体上发布销售广告。其广告内容大致如下：本公司开发建设的小区环境优美，绿化率为60%，设施齐全，并且设有托儿所”。由于绿化率和入学的便利条件，该小区房价虽然比一般楼盘高，但仍被抢购一空。2011年6月15日，该小区交付业主使用，业主们入住后发生了下列事件：
(1)乙的儿子刚刚3岁，夫妻两人要工作，孩子很需要人照顾。当初正是看中广告所称的托儿所，才买下该小区的房子，但是入住后，始终未找到该托儿所。乙多次催问无果后，终将儿子送入较远的托儿所，为此乙要求甲公司承担违约责任，甲公司以“设有托儿所”一事并未纳入购房合同，不具有约束力为由拒绝承担责任。
(2)丙将其所购房屋出租给丁使用，并签订了租赁合同，其合同中约定：房屋租金为3500元/月，按季预付，物业费由丁缴纳。丁租下该房屋后，由于对物业公司的服务不满，一直拒绝缴纳物业费。2011年9月，丁未经丙同意将该房屋转租给戊，丙得知后强烈反对，并主张解除与丁的租赁合同，要求戊腾退房屋。
(3)因甲公司原因，庚购下房屋后一直未能取得房屋产权证，经查，庚与甲公司购房合同总价款为180万元，双方约定甲公司应当自该小区交付使用之日起3个月内为庚办理房屋产权证，否则应当承担合同总价款20%的违约金。庚就该事项诉至人民法院，要求甲公司及时办理房屋产权证，并支付36万元的违约金。庚起诉后，甲公司于2011年10月5为其办妥房屋产权证，经查，由于迟延办理房屋产权证给庚造成的实际损失为10万元，甲公司向人民法院请求降低违约金。
(4)辛住后发现，所购房屋套内建筑面积比合同约定的套内建筑面积缩水5%，要求与甲公司解除商品房买卖合同。
根据上述内容，分别回答下列问题：

甲公司要求降低违约金的主张是否能够得到人民法院的支持说明理由。

间接观察法按观察对象来分，可以有店铺观察、（）和（）等几种。

Yawning sends out certain messages---either “Oh, this movie is boring”or I probably need to get some sleep”. But did you know that a yawn can also help your brain to cool down when it is so overheated?

A new study, led by a research team of Princeton University, has indicated that yawning could be the brain’s natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily.com.

The research team did an experiment on 160 people , 80 in summer and 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.

When people yawn, their jaw is also stretched, which increases blood flow and may also help cool the brain.

The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawn. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.

However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.

According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.
