The primary focus of the passage is on which of the following?
The primary focus of the passage is on which of the following?
The correct option is B Describing new theoretical model and noting that it explains the nature of observations made of a particular natural phenomenon.
The most appropriate answer is Describing new theoretical model and noting that it explains the nature of observations made of a particular natural phenomenon. The author describes the new theoretical model in the first paragraph; in the final paragraph the author states that the data obtained from actual observations, which are discussed in the second and third paragraphs, is consistent with the new theoretical model.
Comparing two scientific theories and contrasting the predictions that each would make concerning a natural phenomenon is not correct; the computer model confirmed the astronomers' hypothesis that meteor streams broaden with time, and although the model yielded an unexpected result, the passage does not contrast the predictions yielded by competing theories.
Analyzing recent data derived from observations of an actual phenomenon and constructing a model to explain the data is not correct because it reverses the order of events. The model yielded a prediction that was subsequently confirmed by observational data, the model was not constructed to explain the data.
The remaining options are not correct because the passage makes no reference to further areas for research, and only a single phenomenon is described in the passage.
