Subsidies vs. Trade Barriers

Steps:

• Define government subsidy as financial aid to lower production costs for domestic firms.
• Review choices: Identify direct financial supports versus import restrictions.
• Classify A as a quantity limit on imports, not financial aid.
• Confirm B, C, D provide monetary benefits to producers.

Why the others are wrong:

• B: Interest-free loans reduce borrowing costs, directly subsidizing producers.
• C: Profits tax reductions lower fiscal burdens, acting as indirect subsidies.
• D: Transfer payments deliver direct cash support to domestic industries.

Final answer: A
