Multiple choice

Increase in errors in our weather computing patterns is most parallel to which of the following:

Directions: Answer the given question based on the following passage:

Numerical weather prediction was a field initiated by Lewis Richardson in 1920s to forecast weather prediction. However, with the calculation of the weather pattern of one day took him more than fifteen weeks of preparation! It was in the 1950s, after the development of supercomputers, that the science of numerical weather prediction gained ground. With technology evolving at breakneck speed, the more powerful supercomputers are now able to compute millions of inputs and datasets to further increase the odds of weather prediction. However, because the formulae used in such calculations have innate imperfections, the errors resulting from the increasing inputs and datasets also grow along with our knowledge of the weather patterns.
Atmosphere is always in a state of flux, and that, in itself lengthens the odds of weather predictions being spot on. The atmospheric predictions are based upon a process that takes a sample of the fluid and by using thermodynamics equations, fluid dynamics, and millions of databases, estimates the state of the fluid at a time in the future. Since the sample of the fluid is taken as, but mathematically is not, the perfect representative of the state of the entire fluid, the long shot becomes an even longer shot.

 

  1. The area of a cake wedge increasing with the distance from the centre

  2. The growth rings in a tree growing in number with passing years.

  3. The number of insects hitting the windscreen of a car and dying on a road trip.

  4. A bacterium getting mutated into a more virulent organism.

  5. A student wrongly attempting a jumbled paragraph question, which in turn affects at least one other answer.

A Correct answer
Explanation

(1) Correct; even though the angle of the cake wedge as a part of the whole circle (cake) remains constant, the size keeps increasing. Similarly, even though the number of errors remains constant, their effect keeps increasing. (2) Incorrect; the number of the rings of a tree grows in a linear manner, not exponentially. (3) The number of insects hitting a windscreen will vary, and as such may or may not increase with every trip. (4) Incorrect; a bacterium's mutation is not analogous in any way to the exponential growth in the errors in weather prediction. (5) Incorrect; one mistake necessarily messes up another answer, but not the whole test.
