某工程项目施工采用了包工包全部材料的固定价格合同。工程招标文件参考资料中提供的用砂地点距工地4km。但是开工后,检查该砂质量不符合要求,承包人只得从另一距工地20km的供砂地点采购。而在一个关键工作面上又发生了几种原因造成的临时停工:4月20日至4月26日承包人的施工设备出现了从未出现过的故障;应于4月24日交给承包人的后续图纸直到5月10日才交给承包人;5月7日到5月12日施工现场下了该季节罕见的特大暴雨,造成5月11日到5月14日该地区的供电全面中断。 [试问] 由于供砂距离的增大,必然引起费用的增加,承包人经过仔细认真计算后,在业主指令下达的第3天,向业主的监理工程师提交了将原用砂单价每吨提高5元人民币的索赔要求。作为一名监理工程师您批准该索赔要求吗为什么

Passage Seven It is hard to track the blue whale, the ocean’s largest creature, Which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 43 days monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of a exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second--slower than through land but faster than through air. What is most important, different layers of. ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low- frequency ones can often travel thousands of miles. It can be inferred from the passage that ______.
A. new radio devices should be developed for tracking the endangered blue whales
B. blue whales are no longer endangered with the use of the new listening system
C. opinions differ as to whether civilian scientists should be allowed to use military technology
D. military technology has great potential in civilian use
