The sentence conveys that the policy was designed to be wide-ranging and cover all necessary aspects, indicating that it was meant to be thorough and inclusive in scopeThe word ``comprehensive'' aptly describes such a policy because it means complete and covering all or nearly all elements or aspectsThis makes ``comprehensive'' the best choice for the first blank
However, despite the policy’s broad and thorough intentions, the sentence goes on to mention difficulties encountered during its implementationThis suggests that putting the policy into practice was not smooth or easyThe word ``problematic'' fits well here, as it describes something that causes problems or difficultiesUsing ``problematic'' in the second blank effectively highlights the contrast between the policy’s ambitious design and the challenges faced during execution
Therefore, the sentence as a whole expresses that while the policy aimed to be all-encompassing, it was met with significant obstacles in practice
Hence, the correct choices are (A) comprehensive for the first blank and (B) problematic for the second
