Explanation:

First Question (Ebola Outbreak Term)

• Epidemic: Defined as a disease outbreak affecting many people in a specific region (here, West Africa countries in 2014 - 2016).
• Pandemic: Requires global spread (Ebola was regional, not global).
• Idiopathic: Means unknown cause (not about outbreak scope).
• Endemic: Refers to a disease regularly found in a particular area (Ebola outbreak was a sudden, widespread event in the region, not regular). So "Epidemic" fits.

• Indirect contact: Involves intermediate objects (fomites), not a living carrier.
• Direct contact: Requires direct person - to - person or close contact (mosquito is a carrier, not direct contact).
• Vector - borne: Transmission via a vector (living organism like a mosquito) that transmits the pathogen. A malaria - infected mosquito biting a person is vector - borne transmission.

Answer:

A. Epidemic

Second Question (Malaria Transmission)
