Which claim is not defensible a. we should make owning more than one car illegal. b. the price of oil is linked to the stability of a country government. c. housing costs can be reduced by increasing real estate development. d. making health insurance more available drives down the costs of health care.

The correct answer is A. The claim that states that owning more than one car shoud be made illegal is not defensible, as it is contrary to the constitutional right on property.

Private property is protected by the Fifth Amendment to the Constitution of the United States, and should not be violated neither by individuals nor the government. If having more than one car was made illegal, the law that made it would be illegal, as it would be contrary to this amendment.

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
