Question

how do embargoes differ from other trade barriers such as quotas and tariffs?
a. embargoes can have a negative effect on domestic production.
b. embargoes lead to reductions in foreign economic investments.
c. embargoes cause an end to all trade across a range of goods.
d. embargoes are often used to protect domestic industries.

Explanation:

The question is about how embargoes differ from other trade barriers (quotas, tariffs). Option C states embargoes cause an end to all trade across a range of goods. Embargoes are a complete ban on trade with a country (or for certain goods), while quotas limit quantity and tariffs are taxes on imports—so embargoes stop trade for a range of goods, unlike quotas/tariffs which restrict rather than end. Other options: A and B are about effects (not differences), D is about protecting industries (true for tariffs/quotas too, not a difference).

Answer:

C. Embargoes cause an end to all trade across a range of goods.
