Comprehension

Different sciences exhibit different science cultures and practices. For example, in astronomy, observation– until what is today called the new astronomy– had always been limited to what could be seen within the limits of optical light. Indeed, until early modernity the limits to optical light were also limits of what humans could immerse themselves with their limited and relative perceptual spectrum of human vision. With early modernity and the invention of lenses for optical instruments– telescopes– astronomers could begin to observe phenomena never seen before. Magnification and resolution began to allow what was previously imperceptible to be perceived– but within the familiar limits of optical vision.  Galileo, having learned of the Dutch invention of a telescope by Hans Lippershey, went on to build some hundred of his own, improving from the Dutch to nearly 30x telescopes– which turn out to be the limit of magnificational power without chromatic distortion. And it was with his own telescopes that he made the observations launching early modern astronomy (phases of Venus, satellites of Jupiter, etc.). Isaac Newton’s later improvement with reflecting telescopes expanded upon the magnification-resolution capacity of optical observation; and, from Newton to the twentieth century, improvement continued to the later very large array of light telescopes today– following the usual technological trajectory of “more-is-better” but still remaining within the limits of the light spectrum. Today’s astronomy has now had the benefit of some four centuries of optical telescope. The “new astronomy,” however, opens the full known electromagnetic spectrum to observation, beginning with the accidental discovery of radio astronomy early in the twentieth century, and leading today to the diverse variety of EMS telescopes which can explore the range from gamma to radio waves. Thus, astronomy, now outfitted with new instruments, “smart” adaptive optics, very large arrays, etc., illustrates one style of instrumentally embodied science– a technoscience. Of course astronomy, with the very recent exceptions of probes to solar system bodies (Moon, Mars, Venus, asteroids), remains largely a “receptive” science, dependent upon instrumentation which can detect and receive emissions.
Contemporary biology displays a quite different instrument array and, according to Evelyn Fox-Keller, also a different scientific culture. She cites her own experience, coming from mathematical physics into microbiology, and takes account of the distinctive instrumental culture in her Making Sense of Life (2002). Here, particularly with the development of biotechnology, instrumentation is far more interventional than in the astronomy case. 
Microscopic instrumentation can be and often is interventional in style: “gene-splicing” and other techniques of biotechnology, while still in their infancy, are clearly part of the interventional trajectory of biological instrumentation. Yet, in both disciplines, the sciences involved are today highly instrumentalized and could not progress successfully without constant improvements upon the respective instrumental trajectories. So, minimalistically, one may conclude that the sciences are technologically, instrumentally embodied. But the styles of embodiment differ, and perhaps the last of the scientific disciplines to move into such technical embodiment is mathematics, which only contemporary has come to rely more and more upon the computational machinery now in common use.

Question: 1

To which one of the following instruments would the characterisations of instruments in the passage be least applicable?

Show Hint

In understanding the use of instruments in scientific inquiry, consider their role in testing hypotheses or gathering data directly related to the subject matter.
Updated On: Jul 4, 2026
  • Milestone
  • Scalpel
  • Saxophone
  • Kitchen oven
Show Solution

The Correct Option is A

Solution and Explanation

Every instrument the passage discusses does something through a working mechanism, a telescope's lenses gather light, a scalpel's blade cuts, a gene-splicing tool edits. A saxophone and an oven fit that same mould, one shaped by keys and reeds to make sound, the other controlled to heat food. A milestone has no working parts at all, it is just a marker someone reads, so the passage's description of instruments as things that observe or intervene simply has nothing to attach to it, which is why milestone is the least applicable.

Question: 2

Which one of the following observations is a valid conclusion to draw from the statement that “the sciences involved are today highly instrumentalised and could not progress successfully without constant improvements upon the respective instrumental trajectories”?

Show Hint

Instrumental progress is crucial in scientific fields, as tools directly affect the capacity to make new discoveries and improve existing knowledge.
Updated On: Jul 4, 2026
  • In both astronomy and microbiology, progress has been the consequence of improvements in the instruments they use.
  • Highly instrumentalised work in the sciences has resulted in the progressive improvement of scientific constants.
  • The growth of scientific technologies has led to the embodiment of progress in the trajectories of improvement.
  • The use of instruments in scientific trajectories must be respected in order to see successful progress in them.
Show Solution

The Correct Option is A

Solution and Explanation

The quoted line simply says progress in these sciences depends on their instruments getting better. Option (1) says exactly that about astronomy and microbiology, the two fields the passage actually discusses, so it just restates the claim. The other three options each swap in something the quote never mentioned, constants improving in option (2), progress being embodied in trajectories in option (3), and an obligation to respect instruments in option (4), none of which appear in the original statement. Since only option (1) sticks to what was actually said, it is the valid conclusion.

Question: 3

None of the following statements, if true, contradicts the arguments in the passage EXCEPT:

Show Hint

Scientific progress often relies on the development of new technologies, and fields such as mathematics can develop new cultures of discovery with the help of computational machinery.
Updated On: Jul 4, 2026
  • Some scientific instruments may be classified as both receptive and interventional in their functions.
  • Isaac Newton’s discovery of gravity was accomplished without the help of instruments.
  • Like telescopes, microscopy has also sought to move beyond the visible spectrum to be able to detect objects that are invisible in that spectrum.
  • Because of the relatively recent entry of computational machinery in mathematics, the field is only now beginning to develop a scientific culture.
Show Solution

The Correct Option is D

Solution and Explanation

A statement only contradicts the passage if the passage actually rules it out, not merely stays quiet on it. The passage never says receptive and interventional traits are mutually exclusive, never discusses whether Newton needed instruments for his work on gravity, and explicitly parallels microscopy's push into invisible ranges with the telescope's own expansion, so options (1), (2) and (3) all sit comfortably with the text. Option (4) is the exception because it mixes up two different ideas, mathematics only recently relying on computational tools does not mean mathematics only recently gained a scientific culture, and the passage clearly treats mathematics as an established science that has simply become tool-dependent later than the others. That mix-up is what the passage's own framing contradicts, making option (4) the answer.

Question: 4

All of the following statements may be rejected as valid inferences from the passage EXCEPT:

Show Hint

When reading comprehension passages, identify the key distinctions the author makes between different concepts, such as the uses of instruments in scientific inquiry.
Updated On: Jul 4, 2026
  • The author distinguishes between the receptive and interventionist uses of instruments in the sciences by comparing astronomy and biology, respectively.
  • Interventionist instruments, or instruments that intervene directly in scientific inquiry, are different from embodied instruments, or instruments that embody scientific inquiry.
  • Isaac Newton’s experiments with reflecting telescopes were the earliest versions of the “new astronomy” referred to in the passage.
  • The advances in telescope made by Newton with reflecting telescopes allowed early modern astronomers to observe the phases of Venus and the satellites of Jupiter.
Show Solution

The Correct Option is A

Solution and Explanation

The passage's central comparison is stated almost word for word, astronomy is receptive while biology, through biotechnology, is interventional, and option (1) simply repeats that comparison, so it holds up as a genuine inference. The other three do not survive a check against the text, option (2) makes up a difference between interventionist and embodied instruments that the passage never draws, option (3) wrongly credits Newton's reflecting telescope with starting the new astronomy when the text ties that to twentieth-century radio discovery, and option (4) wrongly credits Newton's telescopes with observations that the passage assigns to Galileo. With three inferences unsupported and one directly matching the text, option (1) is the answer.
