CAT 2022 Slot 3 — VARC Question 1
The passage below is accompanied by a set of questions. Choose the best answer to each question.
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.
None of the following statements is implied by the arguments of the passage, EXCEPT:
Answer & solution
- A
historically, philosophers have known that the laws of life can be abstracted and applied elsewhere.
- B
purposeful design represents the pinnacle of scientific expertise in the service of human betterment and civilisational progress.
- C
the biological realm is as complex as the mechanical one; which is why the logic of Bios is being imported into machines.
genetic engineers and bioengineers are the same insofar as they both seek to force evolution in an artificial way.
Easy
This is a "double-negative implied" question: "None... is implied... EXCEPT" means exactly one option is genuinely supported by the passage. Find the one statement the author actually argues; the other three either overstate, distort, or contradict the text.
The passage says philosophers in the past "suspected one could abstract the laws of life" but it "wasn't until the complexity of computers... that it was possible to prove this." So they suspected, they did not know. "Known" overstates a mere suspicion. Not implied.
"Purposeful design" is described as a faster, more precise tool of genetic engineers — never glorified as "the pinnacle of scientific expertise" serving "human betterment and civilisational progress." This is grand editorialising the author never makes. Not implied.
This reverses the cause. The passage says proof became possible once machines grew as complex as living things — it does not claim the biological realm is "as complex as the mechanical one" as the reason bio-logic is imported into machines. Distorted causation. Not implied.
The passage states genetic engineering "is precisely what cattle breeders do," differing only in precision/power, and that breeders relied on "diffuse organic evolution" while engineers use "directed artificial evolution." Both force evolution artificially — the difference is degree, not kind. Directly implied.
Option D — genetic engineers and bioengineers (cattle-breeders/herb-gatherers vs. modern engineers) both force evolution artificially; only their control differs.
