select one:

b. tended to support the organized workers.
c. usually remained strictly neutral, refusing to mediate the disputes.
d. sometimes supported the workers and other times supported the owners.

A) Usually supported the owners.

Explanation: In serious labour disputes which arose before 1900, the U.S. government usually supported the owners as it was the time of commercial revolutions and businesses were on the verge of closing down.

As factories were designed there was a need of staff and labour to keep the work in progress. Even in the low wages, the staff had to work and hence the owners were supported.

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.

lincoln presided over the union victory in the american civil war, which dominated his presidency. a former whig, lincoln ran on a political platform opposed to the expansion of slavery in the territories. his election served as the immediate impetus for the outbreak of the american civil war.
