One of the foundations of scientific research is that an experimental result is credible only if it can be replicated—only if performing the experiment a second time leads to the same result. But physicists John Sommerer and Edward Ott have conceived of a physical system in which even the least change in the starting conditions—no matter how small, inadvertent, or undetectable—can alter results radically. The system is represented by a computer model of a mathematical equation describing the motion of a particle placed in a particular type of force field.
Sommerer and Ott based their system on an analogy with the phenomena known as riddled basins of attraction. If two bodies of water bound a large landmass and water is spilled somewhere on the land, the water will eventually make its way to one or the other body of water, its destination depending on such factors as where the water is spilled and the geographic features that shape the water’s path and velocity. The basin of attraction for a body of water is the area of land that, whenever water is spilled on it, always directs the spilled water to that body.
In some geographical formations it is sometimes impossible to predict, not only the exact destination of the spilled water, but even which body of water it will end up in. This is because the boundary between one basin of attraction and another is riddled with fractal properties; in other words, the boundary is permeated by an extraordinarily high number of physical irregularities such as notches or zigzags. Along such a boundary, the only way to determine where spilled water will flow at any given point is actually to spill it and observe its motion; spilling the water at any immediately adjacent point could give the water an entirely different path, velocity, or destination.
In the system posited by the two physicists, this boundary expands to include the whole system: i.e., the entire force field is riddled with fractal properties, and it is impossible to predict even the general destination of the particle given its starting point. Sommerer and Ott make a distinction between this type of uncertainty and that known as “chaos”; under chaos, a particle’s general destination would be predictable but its path and exact destination would not.
There are presumably other such systems because the equation the physicists used to construct the computer model was literally the first one they attempted, and the likelihood that they chose the only equation that would lead to an unstable system is small. If other such systems do exist, metaphorical examples of riddled basins of attraction may abound in the failed attempts of scientists to replicate previous experimental results—in which case, scientists would be forced to question one of the basic principles that guide their work.
Which one of the following most accurately expresses the main point of the passage?
  • a)
    Sommerer and Ott’s model suggests that many of the fundamental experimental results of science are unreliable because they are contaminated by riddled basins of attraction.
  • b)
    Sommerer and Ott’s model suggests that scientists who fail to replicate experimental results might be working within physical systems that make replication virtually impossible.
  • c)
    Sommerer and Ott’s model suggests that experimental results can never be truly replicated because the starting conditions of an experiment can never be re-created exactly.
  • d)
    Sommerer and Ott’s model suggests that most of the physical systems studied by scientists are in fact metaphorical examples of riddled basins of attraction.
  • e)
    Sommerer and Ott’s model suggests that an experimental result should not be treated as credible unless that result can be replicated.
Correct answer is option 'B'. Can you explain this answer?

To determine the main point of the passage, let's analyze each option:
(A) Incorrect. This option suggests that many fundamental experimental results are unreliable, which is too broad. The model focuses on non-replicable results, not all results.
(B) Correct. This option accurately captures the essence of Sommerer and Ott's model, which explains that scientists may fail to replicate results due to the nature of physical systems, making replication nearly impossible.
(C) Incorrect. This option is too extreme by saying experimental results can never be truly replicated.
(D) Incorrect. This option overgeneralizes by saying most physical systems are riddled basins of attraction, which is too strong a claim.
(E) Incorrect. This option incorrectly states the opposite of the model's suggestion.
The best choice is (B) because it accurately reflects the idea that non-replicable results may be due to the nature of the physical systems being studied.

The basin of attraction for a body of water is the area of land that, whenever water is spilled on it, always directs the spilled water to that body.In some geographical formations it is sometimes impossible to predict, not only the exact destination of the spilled water, but even which body of water it will end up in. This is because the boundary between one basin of attraction and another is riddled with fractal properties; in other words, the boundary is permeated by an extraordinarily high number of physical irregularities such as notches or zigzags. Along such a boundary, the only way to determine where spilled water will flow at any given point is actually to spill it and observe its motion; spilling the water at any immediately adjacent point could give the water an entirely different path, velocity, or destination.In the system posited by the two physicists, this boundary expands to include the whole system: i.e., the entire force field is riddled with fractal properties, and it is impossible to predict even the general destination of the particle given its starting point. Sommerer and Ott make a distinction between this type of uncertainty and that known as “chaos”; under chaos, a particle’s general destination would be predictable but its path and exact destination would not.There are presumably other such systems because the equation the physicists used to construct the computer model was literally the first one they attempted, and the likelihood that they chose the only equation that would lead to an unstable system is small. If other such systems do exist, metaphorical examples of riddled basins of attraction may abound in the failed attempts of scientists to replicate previous experimental results—in which case, scientists would be forced to question one of the basic principles that guide their work.Which one of the following most accurately expresses the main point of the passage?a)Sommerer and Ott’s model suggests that many of the fundamental experimental results of science are unreliable because they are contaminated by riddled basins of attraction.b)Sommerer and Ott’s model suggests that scientists who fail to replicate experimental results might be working within physical systems that make replication virtually impossible.c)Sommerer and Ott’s model suggests that experimental results can never be truly replicated because the starting conditions of an experiment can never be re-created exactly.d)Sommerer and Ott’s model suggests that most of the physical systems studied by scientists are in fact metaphorical examples of riddled basins of attraction.e)Sommerer and Ott’s model suggests that an experimental result should not be treated as credible unless that result can be replicated.Correct answer is option 'B'.
