Explanation / Answer

Hi Answer:

Q.1.frame the article in an appropriate context.

Answer: In the present article the presence of harmful algal bloom is discussed. the excessive rise in these blooms in the Erie like is due to mismanagement of the agricultural practices which increases the phosphorous content in the lake and which increases the nutrient concentration in the lake. This all increases the algal blooms in the lake and disturb the normal cycle of the lake. If there will be not the scientific management of this problem then the lake becomes the permanent site of algal blooms.

Q.2.identify the main question or hypothesis in the article
