B Korea

C Japan

D Thailand

6. What are the two ways of producing flexible and transparent electronics?

II. Decide whether the following statements are true or false and prove your answer by citing the article.

1. Further development of unconventional electronic devices does not depend on commercial requirements.

2. All-carbon electronic devices are highly flexible and adhesive.

3. Carbon nanotubes enhance the efficiency of gas sensors.

4. Interfacing electronics with plants and insects will help detect chemical weapons, pollution and infections.

5. The electronics attached to animals and plants cannot function after the death of the animal or plant.

III. Make up a summary of the article using special expressions from appendix on p. 47.

IV. Divide into two teams. One team are the researchers that want to implement integrating nanoelectronic devices onto live plants and insects. The other team are the environmentalists who are against it. Have a debate providing your arguments.

V. Think of possible ways to use nanoelectronic devices integrated onto live plants and animals at home. Discuss these ways with your partner.
