Arrange the following words: rainy season/ dirty water/ the/ during the/ pools of/ become/ they
I think a word is missing in your question.Also think 'they' doesnot fit in this phrase. then it can be-
During the rainy season, the_________, they become pools of dirty water.
During the rainy season, the _________become pools of dirty water.
the word should probably be potholes. I suggest u clarify this with ur eng. tr.
