Answer to Question 1

Ans: A, C, D, E
Feedback:
Changes to water supplies and increased flooding may make some areas more vulnerable to diarrheal diseases. Experts predict that common vector-borne diseases such as malaria and dengue fever will affect larger geographic areas as the vectors that carry the diseases find agreeable climates in expanding areas. Climate change will also affect air quality. The WHO estimates that 300,000 million people have asthma and will face increased disease burden from climate change. There is no association of increased incidence of lung cancer with climate change.
