Final answer:
The most appropriate answer to describe thorough research is Option d). 'Comprehensive'. Terms 'reliable' and 'valid' are vital for research measurements, and using secondary data should be 'nonreactive'. Avoiding confirmation bias and making 'economically sensible' choices are also important considerations in research and democratic governance.
Step-by-step explanation:
The question asks to select the word that best describes research that covers every aspect of an issue comprehensively. From the given options, the most suitable term to describe such thorough research is 'comprehensive'. Therefore, the answer to 'The research is noteworthy in that it leaves no part of the issue unexamined' would be d) Comprehensive.
A measurement in research must reflect what it's supposed to and consistently provide the same results under the same conditions, thus the relevant terms here are a) reliable and c) valid. In discussing different aspects of using secondary data, a) nonreactive generally describes a method that doesn't influence or alter the subject being studied.
When examining evidence in research, it's crucial to avoid confirmation bias, which means individuals should not 'D. look only for evidence that supports the idea' but rather should consider all relevant data, regardless of whether it supports or refutes an idea. In evaluating governance, there is no guarantee a democratic government will always make decisions that are economically sensible. This means choices should be wisely considered and substantiated, but there is no certainty that they will always be economically sensible.
