Researchers have created electronic devices that become soft when implanted inside the body and can grip 3-D objects, such as large tissues, nerves and blood vessels. The device is stiff at room temperature so the surgeon can implant the device, but soft and flexible enough to wrap around 3-D objects so the body can behave exactly as it would without the device. Scientists from the University of Texas at Dallas and the University of Tokyo said the biologically adaptive, flexible transistors might one day help doctors learn more about what is happening inside the body, and stimulate the body for treatments.
Conclusion: Scientists from the University of Texas at Dallas and the University of Tokyo said the
biologically adaptive, flexible transistors might one day help doctors learn more about what is happening inside the body, and stimulate the body for treatments. Which of the following, if true, would most strengthen the conclusion drawn by the researchers?
1. It takes a few weeks for the rigid devices to become soft after they are implanted in the body.
The statement does not affect the conclusion. Incorrect
2. The polymers used in the device do not respond to the body’s environment.
This statement mentions that the device is not biologically adaptive and weakens the conclusion. Incorrect
3. The device morphs with the living tissue.
This statement strengthens the conclusion since if the device morphs (adapts or mixes completely like a living organ) with the living tissue, this will help doctors learn more about what is happening inside the body, and stimulate the body for treatments. Correct
4. The device sometimes loses its electronic properties after it is implanted in the body.
This statement weakens the conclusion since the device sometimes loses its electronics properties and hamper the study of scientists. Incorrect.
5. By using an organic semiconductor, the researchers were able to cut the cost of the device.
The conclusion is not about the cost of the device. Incorrect
