Multiple choice

In the passage given, the two portions in boldface play which of the following roles?

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 first sentence draws a conclusion, and the second strengthens the conclusion.

  2. The second sentence draws a conclusion and the first sentence weakens the conclusion drawn.

  3. Both the sentences provide evidence about the inexactness of weather prediction.

  4. Both the sentences provide evidence about a conclusion that is not stated in the passage.

  5. The first sentence sets up a reason, and the second sentence explains that reason.

C Correct answer
Explanation

(1) Incorrect; the first sentence provides an alternate scenario, not a conclusion to the argument. (2) Incorrect; the first sentence provides an alternate scenario, not a conclusion to the argument. (3) Correct; both the sentences highlight how, due to a number of factors, weather prediction remains inexact. (4) Incorrect; the relation of the sentences with the conclusion cannot be predicted without knowing the conclusion. (5) Incorrect; both sentences elucidate different reasons for the inexactitude of weather prediction.
