Passage A
In the philosophy of science, the traditional view maintains that scientific models represent physical reality by approximating fundamental laws of nature. However, a rigorous examination of model-building practices reveals a fundamental tension: the predictive success of a model almost invariably depends on deliberate distortion. To make complex physical systems mathematically tractable, physicists routinely introduce radical idealizations—such as frictionless planes, point masses, and perfectly isolated thermodynamic systems. These abstractions are not merely provisional simplifications awaiting eventual refinement; rather, they are structural fictions without which the explanatory apparatus of the theory cannot function.

Consequently, scientific laws derived within these idealized frameworks cannot be said to hold true of the messy, unconstrained world. When laws are formulated as universal claims, they describe how objects would behave in artificial, counterfactual environments rather than how they actually behave in concrete reality. Therefore, scientific models are best understood not as literal descriptions of physical systems, but as self-contained fables that demonstrate causal mechanisms under strictly specified, non-actual conditions.

Passage B
Critics of scientific realism frequently cite the ubiquity of idealization as evidence that scientific models fail to depict objective reality. This skepticism, however, misconstrues the epistemic function of abstraction. Scientists rarely rely on a single, all-encompassing model to explain a complex phenomenon. Instead, they employ an array of distinct, partially idealized models, each accentuating different physical parameters while disregarding others.

Crucially, when multiple independent models—each incorporating distinct simplifications—converge on the same underlying invariant relationship, this convergence provides robust empirical justification for the reality of that relationship. Far from obscuring the world, deliberate idealization functions as a cognitive filter, isolating relevant structural dependencies from background noise. The target of scientific realism is not the literal accuracy of isolated model assumptions, but the network of relational structures that persist across varied modeling frameworks. Thus, model distortion is an intentional representational strategy that illuminates, rather than negates, genuine physical structure.

Based on the passages, which of the following statements represent points on which the authors of BOTH Passage A and Passage B would agree? (Select all that apply.)

  1. Scientific models routinely incorporate assumptions and simplifications that do not literally describe physical reality.Answer
  2. An individual scientific model typically does not capture every physical factor operating in a real-world system.Answer
  3. C
    The primary justification for scientific realism rests on the convergence of multiple independent models on invariant relationships.
  4. D
    The idealized assumptions used in constructing scientific models represent temporary flaws that should be eliminated as theories advance.
  5. E
    Scientific models fail to provide genuine insights into the objective structure of the physical universe.

Answer

The statements establishing that models routinely incorporate non-literal simplifications and that an individual model does not capture every physical factor operating in a real-world system represent shared views between both authors.
Both passages share the baseline descriptive premise that scientific modeling fundamentally relies on non-literal abstractions (idealizations) and that individual models purposefully emphasize selected parameters while disregarding other elements of complex real-world phenomena.

Step-by-Step Solution

1
Analyze Passage A's central claims regarding the nature and structure of scientific models.
Passage A establishes that models rely inherently on deliberate distortions and abstractions (such as frictionless planes and point masses) to make systems mathematically tractable, meaning individual models do not describe concrete reality in an all-encompassing, literal way.
Identify the foundational premises accepted by the first author.
2
Analyze Passage B's concessions and foundational claims regarding idealization.
Passage B agrees that idealizations and model distortions are ubiquitous and that single models focus on specific parameters while disregarding others, even though Passage B reaches a more optimistic conclusion about structural realism.
Identify the overlap in baseline descriptive assumptions between both texts.
3
Evaluate each answer choice against textual evidence from both passages.
Both authors agree that models routinely use non-literal simplifications and that individual models omit certain physical factors. The other claims reflect points raised exclusively by one author, rejected by one author, or explicitly contradicted by the text.
Isolate statements that require no unstated assumptions and are definitively affirmed by both authors.
