Paragraph A
Saving lives Delivering medical supplies to hard-to-reach places has been an issue for years.
Worldwide, more than 2 billion people lack access to essential life-saving supplies, such as blood and vaccines.
In the African nation of Rwanda, for example, several remote health clinics do not have sufficient quantities of blood and other healthcare products.
Paragraph B
As a result, many people die of treatable illnesses.
A company called Zipline is trying to address this problem.
It uses drones to transport medical supplies around Rwanda.
In the past, it took hours for packages of medicine to reach some health clinics.
However, a drone could now deliver medicine in 30 minutes.

Around 75,000 people lost their homes, and at least 15 died.
After the storm, drones photographed the damage.

Paragraph F

As well as finding poaches, drones can be used to track animals.
