Read the following passage and determine the text structure. When a river receives a lot of extra water it may flood. During a flood there is plenty of water, and most people wouldn’t think that dehydration was a serious risk, but flood waters are mostly polluted and not safe to drink. People who drink the contaminated water may suffer from illnesses or diseases such as typhoid. You can prepare for flooding by filling many containers with fresh clean drinking water. You can also use sandbags to protect your house and to soak up the water. Be prepared and be safe.
