Final answer:
Both conservatives and liberals seek to free the U.S. from harmful events and ideas, such as war and poverty, through different approaches; hence, the correct answer is d. Both of the above.
Step-by-step explanation:
The question of which group is characterized by a policy of wanting to free the U.S. from harmful events and ideas, such as war and poverty is indicative of a general desire to improve societal conditions, which is a goal shared to varying degrees and through different means by many political groups. However, it doesn't pinpoint a specific political orientation, since both conservatives and liberals aim to protect the U.S. from what they each consider harmful, through their own respective policies.
Historically, liberals have supported a larger government role in providing social welfare programs and addressing issues like poverty and inequality, which they argue can prevent harmful societal events. On the other hand, conservatives have argued for smaller government with a focus on personal responsibility and economic freedom but tend to favor increased spending in areas such as military and law enforcement. Both groups look to policies they believe will secure safety and prosperity for the country, though they disagree significantly on the means to achieve these ends.
Given this context, the answer is d. Both of the above, since both conservatives and liberals seek to protect the nation from what they see as harmful, though through different approaches.
