B. Read the informational text below. Identify the sentences that show cause and effect: The rainy season is here again. Although some people wel- come the coming of rain, some will agree that the rain also brings with it a lot of problems. For one, streets will again be flooded when the strong rains come. Why do the streets get flooded when it rains? There are several reasons for this. First, most of the canals and sewerage systems are clogged. So when it rains, the flow of water is ob- structed. This clogging is caused by another factor: the improp- er disposal of waste. Another reason for the flood is that there are not enough trees and plants to absorb the water. The once- upon-a-time green forests and mountains have been replaced by tall buildings and other business establishments. When the floods come, other problems arise. There is traf- fic jam, the onset of diseases, especially among children, and damage to properties. ​
