Q1:

There are two kinds of molecules used to make some nano-robots: one that reacts positively to water and the other negatively.

Nano-Sentinel-like robots are likely to be used to inject people to convert them into robots, cell by cell.

Some hydro gels turn sticky when an electric current is passed through them; this potentially has very useful applications.

Robots made from smart materials are likely to become part of our everyday lives in the future

Q5:

If you go faster in a car, you will tend to consume more fuel, but the converse is not necessarily true. In the same way, increased entropy does not necessarily mean greater accuracy of a clock.

The further you go in a car, the more fuel you use. In the same way, the faster you go in a car, the less time you use.

If you measure the speed of a car with a grandfather clock, the result will be different than if you measured it with an atomic clock.

The further and faster you go in a car, the greater the amount of fuel you will use, the greater the amount of heat produced and, hence, the greater the entropy.

Q6:

The relationship between accuracy and entropy may not apply to all clocks.

Researchers found that the heat produced in a system is the price paid for increased accuracy of measurement.

There is no difference in accuracy between an inefficient grandfather clock and an atomic clock.

In designing clocks for quantum computers, both precision and heat have to be taken into account.

Q8:

CAT

Reading Comprehension

Medium

Q8:

the arrow of time has not yet been tested for atomic clocks.

quantum computers are likely to produce more heat and, hence, more entropy, because of the emphasis on their clocks' accuracy

grandfather clocks are likely to produce less heat and, hence, less entropy, because they are not as accurate.

a clock with a 50-nanometre-thick membrane of silicon nitride has been made to vibrate, producing electric currents.

Q17:

Economic reforms have benefitted many Brazilians, but they are unaware of the impending problems from rising inequalities in their society.

With rising incomes and falling unemployment, most Brazilians are being misled into thinking that their economy is doing well.

Good economic indicators have masked the unfair taxation of the poor that is likely to destabilise the Brazilian economy in the next few years.

Most Brazilians feel they have benefitted from recent economic events, but the poor continue to be dealt unfairly by the state.

Q21:

Despite some detractors, hard work is essential in today's world to enable economic progress, for education and health and to propel innovations that make life easier.

Some believe that hard work has been glorified to the extent that it has become meaningless, and led to greater idleness, but it has also had enormous positive impacts on everyday life.

Hard work has overtaken all aspects of our lives and has enabled economic prosperity, but it is important that people reserve their leisure time for some idleness.

While the idealisation of hard work has propelled people into meaningless jobs and endless activity, it has also led to tremendous social benefits from prosperity and innovation.

Q23:

Intuition draws from deep memory, and may not be related to data, but to decades of diverse qualitative experience.

Intuition is infinitely richer than big data which is based on rational thought and accomplishes more than what big data can.

Intuitions are neuro-chemical firings based on pattern recognition and draw upon a rich and vast database of experiences.

Intuitions are automatic processes and are therefore faster than rational thought, and so decisions based on them are better.
