Scientific Applications of Sensor Technology

What is one of the main challenges of air conditioners in the 21st century?

• They are too expensive to produce.

• They contribute to global warming.

• They are not energy efficient.

• They are difficult to install.

How do air conditioners contribute to the warming of cities?

• By releasing cold air into the atmosphere.

• By using solar energy inefficiently.

• By moving heat from inside to outside.

• By increasing humidity levels.

What was an unintended consequence of aggressive wildfire suppression policies?

• Increased biodiversity in forests.

• Denser and more flammable forests.

• Reduction in forest area.

• Decrease in forest wildlife.

What strategy can help make wildfires cooler and less destructive?

• Building more roads in forests.

• Increasing the number of fire stations.

• Planting more trees.

• Controlled burns and selective logging.

How did agriculture contribute to the spread of malaria?

• By reducing the number of mosquitoes.

• By creating more breeding grounds for mosquitoes.

• By decreasing human population density.

• By increasing the use of pesticides.

What is Plasmodium falciparum?

• A vaccine for malaria.

• A pesticide used to control malaria.

• A strain of malaria that spread from gorillas to humans.

• A type of mosquito.

What was the original purpose of the global network of sensors?

• To detect nuclear tests.

• To track whale migrations.

• To study volcanic activity.

• To monitor weather patterns.

How have the sensors used for detecting nuclear tests benefited other scientific fields?

• By providing data on whale locations.

• By increasing the number of nuclear tests.

• By reducing the cost of scientific research.

• By improving agricultural practices.

What is one of the benefits of the data collected by the global sensor network?

• It helps in predicting volcanic eruptions.

• It reduces the cost of building sensors.

• It increases the number of nuclear tests.

• It provides data on agricultural yields.

What is the main focus of the promotional segment?

• Promoting online courses for learning math and science.

• Introducing a new wildlife documentary.

• Selling air conditioners.

• Advertising a new book on climate change.
