This question asks about the stated purpose of the "science of law" as the passage frames it, distinguishing the theoretical science of law from the practical science of law.
Reading the option set against the opening sentence of the passage, only one option tracks the express purpose assigned to the science of law rather than to its practical counterpart.
Hence, the correct answer is Pure knowledge based on reality.
The question is looking for the method that the passage attributes to the practical science of law, as opposed to methods associated with other branches of jurisprudence.
Only the option tied to judicial application of law reflects what the passage actually says about the prevailing method.
Hence, the correct answer is Employed by judges for application of law.
This question asks what dominates judicial thinking according to the passage's account of the jurist's mindset.
The passage's own language about the jurist's thinking being conditioned by practical purposes leaves only one option standing.
Hence, the correct answer is Practical purposes followed by judicial science.
The question asks for the reason the passage gives for juristic science losing its scientific character, so the answer should trace back to the specific sentence addressing that loss.
Since the passage explicitly links the loss of contact with reality to the abstractions and deductions of juristic science, that is the stated cause of its declining scientific temperament.
Hence, the correct answer is Judicial abstractions and deductions are different from reality.
This question tests recall of how the passage describes the formulation of legal propositions that juristic science supplies to judges.
The passage's own description of legal propositions being cast in the most general terms to cover as many cases as possible points to generality, not exclusivity or any external interest, as their basis.
Hence, the correct answer is Generalised possibility.
This question asks what judges expect of ordinary people's conduct according to the passage's closing lines.
The passage's explicit statement about what judges expect of men's conduct matches only the option tying conduct to court-decided rules.
Hence, the correct answer is The conduct of man be based on rules decided by courts.
