Good job! I would recommend you tweek the first sentence, because its a run on sentence. Try divided up the sentence. Also, add a concluding sentence.
It is easy to identify a main idea that is directly expressed in the text. Main ideas are often found at the beginning of paragraphs. The first sentence often explains the subject being discussed in the passage. Main ideas are also found in the concluding sentences of a paragraph. hope that helped
