Question

read the excerpt from the constitution of the united states, article 1, section 8
congress shall have power to regulate commerce with foreign nations, and among the several states.
this excerpt reinforces the idea of
○ federal supremacy
○ habeas corpus
○ balance of powers
○ judicial review.

Explanation:

首先分析每个选项：“federal supremacy（联邦至上）”指联邦政府权力高于州政府，美国宪法规定国会有权管理州际和对外贸易，体现联邦在商业调控上的至上权力；“habeas corpus（人身保护权）”与公民人身自由相关，和商业调控无关；“balance of powers（权力制衡）”强调三权分立制衡，此条款未体现；“judicial review（司法审查）”是法院审查法律合宪性，也不相关。所以该条款强化联邦至上理念。

Answer:

A. federal supremacy
