The passage
Nature has all along yielded her flesh to humans. First, we took nature's materials as food, fibers, and shelter. Then we learned to extract raw materials from her biosphere to create our own new synthetic materials. Now Bios is yielding us her mind-we are taking her logic.
Clockwork logic-the logic of the machines-will only build simple contraptions. Truly complex systems such as a cell, a meadow, an economy, or a brain (natural or artificial) require a rigorous nontechnological logic. We now see that no logic except bio-logic can assemble a thinking device, or even a workable system of any magnitude.
It is an astounding discovery that one can extract the logic of Bios out of biology and have something useful. Although many philosophers in the past have suspected one could abstract the laws of life and apply them elsewhere, it wasn't until the complexity of computers and human-made systems became as complicated as living things, that it was possible to prove this. It's eerie how much of life can be transferred. So far, some of the traits of the living that have successfully been transported to mechanical systems are: self-replication, self-governance, limited self-repair, mild evolution, and partial learning.
We have reason to believe yet more can be synthesized and made into something new. Yet at the same time that the logic of Bios is being imported into machines, the logic of Technos is being imported into life. The root of bioengineering is the desire to control the organic long enough to improve it. Domesticated plants and animals are examples of technos-logic applied to life. The wild aromatic root of the Queen Anne's lace weed has been fine-tuned over generations by selective herb gatherers until it has evolved into a sweet carrot of the garden; the udders of wild bovines have been selectively enlarged in a "unnatural" way to satisfy humans rather than calves. Milk cows and carrots, therefore, are human inventions as much as steam engines and gunpowder are. But milk cows and carrots are more indicative of the kind of inventions humans will make in the future: products that are grown rather than manufactured.
Genetic engineering is precisely what cattle breeders do when they select better strains of Holsteins, only bioengineers employ more precise and powerful control. While carrot and milk cow breeders had to rely on diffuse organic evolution, modern genetic engineers can use directed artificial evolution-purposeful design-which greatly accelerates improvements.
The overlap of the mechanical and the lifelike increases year by year. Part of this bionic convergence is a matter of words. The meanings of "mechanical" and "life" are both stretching until all complicated things can be perceived as machines, and all self-sustaining machines can be perceived as alive. Yet beyond semantics, two concrete trends are happening: (1) Human-made things are behaving more lifelike, and (2) Life is becoming more engineered. The apparent veil between the organic and the manufactured has crumpled to reveal that the two really are, and have always been, of one being.
Question 5
- A"Bios" and "Technos" are both convergent forms of logic, but they generate meanings about the world that are mutually exclusive.
- BA bionic convergence indicates the meeting ground of genetic engineering and artificial intelligence.
- C"Mechanical" and "life" are words from different logical systems and are, therefore, fundamentally incompatible in meaning.
- D"Mechanical" and "life" were earlier seen as opposite in meaning, but the difference between the two is increasingly blurred.
Answer: (D) "Mechanical" and "life" were earlier seen as opposite in meaning, but the difference between the two is increasingly blurred. RC · Science & Technology MCQ
Solution
- The next lines explain: the meanings of 'mechanical' and 'life' are 'stretching until all complicated things can be perceived as machines, and all self-sustaining machines can be perceived as alive'.
- So two once-opposed words now overlap, as D says. A and C claim incompatibility, the opposite of convergence, and B brings in AI as a meeting ground, which is not the point.
Question 6
- AComplex systems; Carrots; Milk cows; Convergence; Technos-logic
- BNature; Bios; Technos; Self-repair; Holsteins
- CNature; Computers; Carrots; Milk cows; Genetic engineering
- DComplex systems; Bio-logic; Bioengineering; Technos-logic; Convergence
Answer: (D) Complex systems; Bio-logic; Bioengineering; Technos-logic; Convergence RC · Science & Technology MCQ
Solution
- The passage moves from complex systems needing bio-logic, to technos-logic imported into life through bioengineering, to the convergence of the two.
- D captures all of these. A, B and C include illustrative details (carrots, milk cows, Holsteins, self-repair) instead of the central ideas.
Shortcut. Keyword sets that contain examples (carrots, Holsteins) are rarely right.
Question 7
- Apurposeful design represents the pinnacle of scientific expertise in the service of human betterment and civilisational progress.
- Bthe biological realm is as complex as the mechanical one; which is why the logic of Bios is being imported into machines.
- Cgenetic engineers and bioengineers are the same insofar as they both seek to force evolution in an artificial way.
- Dhistorically, philosophers have known that the laws of life can be abstracted and applied elsewhere.
Answer: (C) genetic engineers and bioengineers are the same insofar as they both seek to force evolution in an artificial way. RC · Science & Technology MCQ
Solution
- 'Genetic engineering is precisely what cattle breeders do... only bioengineers employ more precise and powerful control', using 'directed artificial evolution'. So genetic engineers and bioengineers both push evolution artificially: C is implied.
- D fails because philosophers only 'suspected' it; proof came later. A is an unsupported superlative. B misstates the reason: Bios logic is imported because mechanical systems became as complicated as living things.
Question 8
- AScientific advances are making it increasingly difficult to distinguish between organic reality and manufactured reality.
- BApparent reality and organic reality are distinguished by the fact that the former is manufactured.
- COrganic reality has crumpled under the veil of manufacturing, rendering the apparent and the real as the same being.
- DThe crumpling of the organic veil between apparent and manufactured reality reveals them to have the same being.
Answer: (A) Scientific advances are making it increasingly difficult to distinguish between organic reality and manufactured reality. RC · Science & Technology MCQ
Solution
- The sentence closes the 'bionic convergence' argument: made things are becoming lifelike and life is becoming engineered, so the line between them has vanished.
- A restates this: scientific advances make organic and manufactured hard to tell apart. B, C and D garble the metaphor, putting 'apparent' versus 'organic' reality or treating the organic as the veil.
