Question

after the 2010 earthquake in haiti, many public health officials predicted a cholera outbreak would occur. why did they make this prediction?
people were drinking contaminated water.
people were inhaling dust from crumbled buildings.
people were eating near contaminated dump sites.
people were boiling their water before use.

Explanation:

Cholera is typically transmitted through contaminated water. After an earthquake, water sources can be disrupted and contaminated. Boiling water would help prevent cholera (so that option is incorrect). Inhaling dust (related to other issues like respiratory problems) and eating near dump sites (not the main cholera transmission route) are less relevant.

Answer:

People were drinking contaminated water.
