背景材料：
一个施工项目，材料费往往是占了施工成本的绝大部分，如果加上预算材料费以外材料消耗，则材料费占工程成本的比重更大。因此，对材料费的控制就成为公路施工成本控制的重点。在工程的整个实施期间，必须有严格的材料计划和管理制度，确保料费成本得到有效控制。某特大桥梁施工项目部拟定了如下两条材料计划的原则和要求：
1．根据施工生产实际情况编制，做到经济合理、切实可行；
2．各部门对材料严格审核。并拟定了材料需要量计划，并由此确定了材料采购计划。
问题：
1．请指出项目部编制材料计划的做法中的不妥之处，并予以改正。
2．编制材料计划的原则和要求是否齐全？如不齐全，请予以补充完善。

A.正确 B.错误 [单项选择]Firefighters are often asked to speak to school and community groups about the importance of fire safety, particularly fire prevention and detection. Because smoke detectors reduce the risk of dying in a fire by half, firefighters often provide audiences with information on how to install these protective devices in their homes.
Specifically, they tell them these things: A smoke detector should be placed on each floor of a home. While sleeping, people are in particular danger of an emergent fire, and there must be a detector outside each sleeping area. A good site for a detector would be a hallway that runs between living spaces and bedrooms. Because of the dead-air space that might be missed by hot air bouncing around above a fire, smoke detectors should be installed either on the ceiling at least four inches from the nearest wall, or high on a wall at least four, but no further than twelve inches from the ceiling. Detectors should not be mounted near windows, entrances A. install smoke detectors in residents’ homes B. check if smoke detectors are properly installed C. develop fire safety programs for schools D. speak to residents about how to prevent fires 我来回答: 提交
