Transcript:

A team of physicists from the US has developed electricity-conducting, environment-sensing, shape-changing robots that are the size of a human cell. The robots are made from incredibly thin layers of graphene and glass. Known as biomorphs, the tiny machines bend when exposed to heat or electricity. They can change in a fraction of a second from 2-D patterns into complex 3-D forms. Team member Paul McEuen says that what he and his colleagues are trying to build can be called an 'exoskeleton' for electronics. Although the robots are tiny, the physicists say that they can carry significant loads. This opens up a whole range of opportunities. For example, the entire computational power of the spaceship Voyager could be placed onto an object the size of a cell.

* Click on the correct answer

US-based physicists have created new robots called biomorphs, and they can change into a variety of different forms and shapes. The US team hope that the robots will be used to create an exoskeleton for future electronics. Scientists from the US have developed tiny robots made from graphene and glass. About the size of a human cell, they can conduct electricity and change shape. The robots can carry a large amount of computing power and may have different applications in the future. Tiny robots have been developed by a team of physicists in the US. The robots can be made to bend by exposing them to heat or electricity. They can conduct electricity and sense the environment. They can also change from 2-D patterns into complicated 3-D shapes. Scientists have created some very small robots that are so powerful that the computing power of the spaceship Voyager could fit on a robot the size of a human cell. Paul McEuen says that they are attempting to build an exoskeleton for electronics.

Result:

A.I. Explanation:

Option 1: "US-based physicists have created new robots called biomorphs, and they can change into a variety of different forms and shapes. The US team hope that the robots will be used to create an exoskeleton for future electronics."
Explanation: This option incorrectly states that the robots are called biomorphs without mentioning their ability to conduct electricity and sense the environment. Additionally, it implies a future hope for the robots' application, which is not explicitly stated in the text. The text emphasizes current capabilities and potential applications rather than future hopes.
Option 2: "Scientists from the US have developed tiny robots made from graphene and glass. About the size of a human cell, they can conduct electricity and change shape. The robots can carry a large amount of computing power and may have different applications in the future."
Explanation: This option accurately summarizes the main points of the text. It mentions the development of tiny robots made from graphene and glass, their size, ability to conduct electricity, and change shape. It also correctly highlights their potential to carry significant computing power and suggests various applications, aligning well with the text's overall theme.
Option 3: "Tiny robots have been developed by a team of physicists in the US. The robots can be made to bend by exposing them to heat or electricity. They can conduct electricity and sense the environment. They can also change from 2-D patterns into complicated 3-D shapes."
Explanation: While this option contains some accurate details about the robots' capabilities, it lacks the broader context of their potential applications and the significance of their size. It focuses too much on specific functionalities without addressing the overall implications of their development, making it incomplete.
Option 4: "Scientists have created some very small robots that are so powerful that the computing power of the spaceship Voyager could fit on a robot the size of a human cell. Paul McEuen says that they are attempting to build an exoskeleton for electronics."
Explanation: This option misrepresents the text by suggesting that the robots are 'so powerful' without mentioning their size and material composition. It also implies a focus on the Voyager's computing power without adequately summarizing the robots' capabilities and potential applications, making it too narrow and not fully representative of the text.
