Identifying Protectionism-Changing Actions Steps:

• Define protectionism as policies restricting imports or subsidizing domestic industries to shield them from competition.
• Analyze "imposing an embargo": This bans imports, increasing protectionism by blocking foreign goods.
• Analyze "reducing subsidies to domestic producers": This cuts financial support, decreasing protectionism by exposing locals to more competition.
• Confirm A pairs an increasing action first with a decreasing one second, matching the question's structure.

Why A is correct:

• Embargo imposition restricts imports, increasing protectionism under trade barrier definitions; subsidy reduction eliminates domestic aid, decreasing it per economic policy standards.

Why the others are wrong:

• B: Both voluntary export agreements and lowering quota levels tighten import restrictions, so both increase protectionism.
• C: Option is incomplete and lacks specified actions for analysis.
• D: Removing quotas decreases protectionism first, while introducing embargoes increases it, reversing the expected order.

Final answer: A
