Article: Environmental health is defined as the control of the factors in the environment that may have harmful effects on people's physical, mental, or social well-being . Because natural disasters expose people to danger by bringing up or threatening their immediate environment, effective management of environmental health after a natural disaster is of great importance. The environmental health measures that must be considered after a natural disaster include the supply of appropriate shelter for individuals or groups of people left homeless, the distribution of safe and accessible water, and the protection and distribution of safe food products and so on. To effectively manage environmental health during and after a disaster, it is important that a state of preparation is in effect before the event actually occurs. During an emergency, success largely depends on making good, rapid judgment and appropriate response measures. High-level decision makers, therefore, must be familiar with sound measures beforehand and should be given an accurate judgment of the disaster's specific effects as quickly as possible. This book is intended to serve as a guide for those who may be called upon to make emergency decisions after disaster strikes. The recommended environmental health measures have been listed in the order of priority in which they should be taken during an emergency. However, each natural disaster is unique in the degree or type of emergency. In response to any given disaster, decision makers may find it necessary to change the priority assigned to any particular measure. Question: We can't do just as the recommended environmental health measures because _ . Options: A: some of the measures have not been taken before B: they are not the same according to different degrees or types of emergency C: they are probably made up by someone without experience D: they can't be changed once they are taken by the experts

Article: A story tells that a senior villager led some other villagers carrying salt day and night to a town in order to trade rice as food the winter.One night they camped in a wilderness with a starry sky above.The senior villager,obeying the tradition passed down from forefathers,took out three blocks of salt and threw them into the campfire,probably to predict the changes of weather in the mountains. All eagerly waited for the old man's"weather report":if the salt in the fire produced crackling sound,they would have good weather in store;if no sound was produced,it then meant the good weather would soon end and a storm would come at any moment. The senior villager looked serious.The salt in the campfire made no sound at all.Convinced by this bad sign,he urged the whole team to set out immediately after daybreak.A young man in the group,however,insisted that they should not start in such a hurry,considering it superstitious to"forecast weather by using salt. It was not until the next afternoon that the young man caught up on the wisdom of the old man when the weather suddenly changed,with cold winds blowing and a snowstorm raging.In fact,the method used by the clan head could be well explained by modem science:whether or not salt produces sound in campfire depends on air humidity .That is to say,when a storm approaches,due to high humidity,the dampened salt blocks will not produce any sound in fire. Question: The senior villager predicted the changes of the weather _ while camping in a wilderness that night. Options: A: by taking out salt B: by burning salt in fire C: in a superstitious way D: depending on his wisdom
