VOICED : Rats with nose for trouble train to save lives in Tanzania

The video discusses the innovative use of rats by the Belgian NGO APOPO to detect landmines and tuberculosis. In Tanzania, rats are trained to sniff out explosives, helping to neutralize over 80,000 landmines in various countries. These rats are lightweight, making them ideal for mine detection without triggering explosions. Additionally, in laboratories, rats are used to detect tuberculosis, significantly increasing detection rates compared to traditional methods. Despite these successes, APOPO is looking to expand their mission to include cancer detection, showcasing the potential of rats in various health and safety applications.

What is the primary reason rats are effective in landmine detection?

• They can dig up the mines.

• They have a strong sense of sight.

• They are too light to trigger the mines.

• They are faster than humans.

How many landmines have been neutralized by the rats according to the transcript?

• Over 30,000

• Over 100,000

• Over 80,000

• Over 50,000

In what way do rats outperform lab technicians in tuberculosis diagnosis?

• They require less training.

• They can screen samples faster.

• They are more accurate.

• They are cheaper to maintain.

What percentage increase in positive TB patient identification is achieved by using rats?

• 20%

• 50%

• 30%

• 40%

What is the next potential mission for the rats as mentioned in the transcript?

• Detecting illegal drugs

• Detecting cancer

• Detecting counterfeit money

• Detecting chemical weapons
