Question 10.

Which one of the following scenarios, if false, could be seen as supporting the passage?
A
Robots made from smart materials are likely to become part of our everyday lives in the future.
B
There are two kinds of molecules used to make some nano-robots: one that reacts positively to water and the other negatively.
C
Some hydrogels turn sticky when an electric current is passed through them; this potentially has very useful applications.
D
Nano-Sentinel-like robots are likely to be used to inject people to convert them into robots, cell by cell.

Question Explanation

Text Explanation

We will check which option when proven false will support the passage:

A: Robots becoming a part of everyday life is neither supported nor opposed in the passage. Thus, Option A is not the answer.

B: Instead of gears and wires, it’s assembled from two kinds of molecules - some that love water and some that avoid it - which interact to allow the bot to skate on top of a pond.

Option B has been clearly mentioned in the passage. Hence, if it is proven false, it will contradict the passage. Option B is not the answer.

C: One team of researchers, for example, has developed a different kind of hydrogel that becomes sticky when exposed to a low-voltage zap of electricity and then stops being sticky when the electricity is switched off.

Option C has been mentioned in the passage. Hence, if it is proven false, it will contradict the passage. Option C is not the answer.

D: No, they won’t be invading our bodies and turning us into Sentinels...

Option D is just the opposite of what has been given in the passage. Hence, if Option D is false, it would support the passage.
