Can someone please HELP ASAP!!!!
I have 2 questions !!

QUESTION 1:
Read the following selection and answer the question.

Children under five years of age are among the most vulnerable groups affected by malaria. There were an estimated 660,000 malaria deaths around the world in 2010, of which approximately 86% were in children under five years of age. In high transmission areas, partial immunity to the disease is acquired during childhood. In such settings, the majority of malarial disease, and particularly severe disease with rapid progression to death, occurs in young children without acquired immunity. Severe anemia, hypoglycemia and cerebral malaria are features of severe malaria more commonly seen in children than in adults.
